I have two research focuses: law/psychology and social/personality psychology. I conduct social/personality psychology research into factors influencing the perceptions of intergroup/interpersonal conflict, and in conjunction with my J.D. degree I conduct law/psychology research into legal decision making and how jurors/judges reach judgments. In each arena my thematic focus is on “Person x Situation” interactions and how the basic aspects of the ''person'' (e.g., affect, behavior, cognition, etc.) interact with the different aspects of ''situations'' to influence human nature.<br />

I am also interested in developing tools to help people better understand and use psychology. [[PsychWiki_-_A_Collaborative_Psychology_Wiki_:About| PsychWiki]] was developed initially as a companion project to the [[USC | Professional Development meetings]] I started at the USC Psychology Department. No single person can master all the different aspects of professional life so PsychWiki is a way to share our unique experiences and skills for the collective benefit of everyone in the field. Hopefully, PsychWiki will be of benefit to our field as a way to create active collaboration and pool our collective resources. <br />
<br />
Based upon the Person x Situation concept, I developed an organizing framework that articulates the components of individual differences and situational constraints upon affect, behavior, and cognition in order to integrate psychological research. Excerpts from a manuscript about the framework can be found [[Organizing Framework | here]]. The framework is useful to researchers as a way to generate research ideas and unify research projects, and I am planning on using the framework as an organizing structure for a psychology textbook.<br />

<hr />
<div>'''How do I determine whether my data are normal?'''<br />
*There are three interrelated approaches to determine normality, and all three should be conducted.<br />
*#Look at a histogram with the normal curve superimposed. A histogram provides useful graphical representation of the data. [[Image:Fe40.png]] - To provide a rough example of normality and non-normality, see the following histograms. The black line superimposed on the histograms represents the bell-shaped "normal" curve. Notice how the data for variable1 are normal, and the data for variable2 are non-normal. In this case, the non-normality is driven by the presence of an outlier. For more information about outliers, see [[What are outliers?]], [[Detecting Outliers - Univariate | How do I detect outliers?]], and [[Dealing with Outliers | How do I deal with outliers?]]. Problem -- All samples deviate somewhat from normal, so the question is how much deviation from the black line indicates “non-normality”? Unfortunately, graphical representations like histogram provide no hard-and-fast rules. After you have viewed many (many!) histograms, over time you will get a sense for the normality of data. <center><table><td>[[Image:V1hn0.png|350px]]</td><td>[[Image:V2hnn0.png|350px]]</td></table></center><br><br><br />
*#Look at the values of Skewness. '''Skewness''' involves the symmetry of the distribution. Skewness that is normal involves a perfectly symmetric distribution. A positively skewed distribution has scores clustered to the left, with the tail extending to the right. A negatively skewed distribution has scores clustered to the right, with the tail extending to the left. Skewness is 0 in a normal distribution, so the farther away from 0, the more non-normal the distribution. The question is “how much” skew render the data non-normal? This is an arbitrary determination, and sometimes difficult to interpret using the values of Skewness. [[Image:Fe40.png]] - The histogram above for variable1 represents perfect symmetry (skewness) and perfect peakedness (kurtosis); and the descriptive statistics below for variable1 parallel this information by reporting "0" for both skewness and kurtosis. The histogram above for variable2 represents positive skewness (tail extending to the right); and the descriptive statistics below for variable2 parallel this information. Problem -- The question is “how much” skew render the data non-normal? This is an arbitrary determination, and sometimes difficult to interpret using the values of Skewness. Luckily, there are more objective tests of normality, described next. <center><table><td>[[Image:V1d5tm.PNG|350px]]</td><td width=50></td><td>[[Image:V2d5tm.PNG|350px]]</td></table></center><br><br><br />
*#Look at established tests for normality that take into account both Skewness and Kurtosis simultaneously. The Kolmogorov-Smirnov test (K-S) and Shapiro-Wilk (S-W) test are designed to test normality by comparing your data to a normal distribution with the same mean and standard deviation of your sample. If the test is NOT significant, then the data are normal, so any value above .05 indicates normality. If the test is significant (less than .05), then the data are non-normal. [[Image:Fe40.png]] - See the data below which indicate variable1 is normal, and variable2 is non-normal. Also, keep in mind one limitation of the normality tests is that the larger the sample size, the more likely to get significant results. Thus, you may get significant results with only slight deviations from normality when sample sizes are large. <center>[[Image:V1v2tn.PNG]]</center><br><br><br />
*#Look at normality plots of the data. “Normal Q-Q Plot” provides a graphical way to determine the level of normality. The black line indicates the values your sample should adhere to if the distribution was normal. The dots are your actual data. If the dots fall exactly on the black line, then your data are normal. If they deviate from the black line, your data are non-normal. [[Image:Fe40.png]] - Notice how the data for variable1 fall along the line, whereas the data for variable2 deviate from the line. <center><table><td>[[Image:V1nqp0.png|350px]]</td><td width=50></td><td>[[Image:V2nqp0.png|350px]]</td></table></center><br><br><br />

<hr />
<div>'''What is a correlation?'''<br />
* Correlation is the measure of the <u>strength</u> and <u>direction</u> of the relationship between the variables<br />
* Direction of the relationship can be either positive or negative. Correlations can vary between -1 and 1. A positive relationship is indicated by a positive value (e.g., ranging from 0 to 1). A negative relationship is indicated by a negative value (e.g., ranging from 0 to -1). [[Image:Fe40.png]] - An example of a positive relationship is the relationship between height and weight. The higher the outcome on one variable, the higher the outcome on the other variable. [[Image:Fe40.png]] - An example of a negative relationship is the relationship between exercise and weight. The higher the outcome on one variable, the lower the outcome on the other variable.<br />
* Strength of the relationship is measured from 0 to 1/-1. The farther the value is away from 0, the stronger the relationship. The approximate criteria for strength is 0 for no effect, .1 for a small effect, .3 for a medium effect, and .5 for a large effect. Notice those values can be either positive or negative, depending upon the direction of the relationship, so a .2 and -.2 relationship indicate the same strength, but different direction<br />
<br />
'''What is a partial correlation?'''<br />
* Partial correlation is the relationship between two variables while controlling for a third variable. The purpose is to find the unique variance between two variables while eliminating the variance from a third variables. <br />
* You typically only conduct partial correlation when the third variable has shown a relationship to one or both of the primary variables. In other words, you typically first conduct correlational analysis on all variables so that you can see whether there are significant relationships amongst the variables, including any "third variables" that may have a significant relationship to the variables under investigation. <br />
* In addition to this statistical pre-requisite, you also want some theoretical reason why the third variable would be impacting the results. <br />
* You can conduct Partial Correlation with more than just 1 third-variable. You can include as many third-variables as you wish.<br />
<br />
<br />
'''Example of partial correlation:''' [[Image:Fe40.png]]<br />
* Output below is for the relationship between "commit1" and "commit3" while controlling for "prosecutor1". "Commit1" measures the participants beliefs about what percent of people brought to trial did in fact commit the crime. "Commit3" measures the participants beliefs about what percent of people convicted did in fact commit the crime. You would predict a positive relationship between those two variables. The top part of the output below represents the bivariate [[What is a correlation? | correlation]] between those two variables, r = .352, p = .000<br />
* "Prosecutor1" measures how well the participants trust/like Prosecutors. "Prosecutor1" is entered as the controlling variable because: (1) statistically, it shows significant relationship to both commit1 and commit3. You can see that significant relationship in the top part of the "Correlations" box below which presents the correlations without controlling for a third variable, (2) theoretically, it is possible that the reason why commit1 and commit3 are connected is because if participants like/trust Prosecutors they may thus be more likely to believe that the Prosecutor is correct and the defendants are guilty. <br />
* Thus, given this plausible (statistical and theoretical) third-variable relationship, it is interesting to note that controlling for "Prosecutor1" did not lower the strength of the relationship between commit1 and commit3 by that much because the outcome while controlling for prosecutor1 was r = .341, p < .001. In other words, the relationship between commit1 and commit3 is NOT due to subjects trusting/liking the prosecutor.<br />

<hr />
<div>== <center> Step 2 - Locating Studies </center> ==<br />
=== How long should searching for articles take? ===<br />
:It is to your advantage to conduct the searching for articles (Step 2) in a compact period of time because you will invariably come across the same abstract over and over again when using different search terms, so if you conduct the search in a compact period of time it will be easier to remember which abstracts you have already read (and decide to pass or keep)<br />
<br />
=== Why should I email listservs? ===<br />
:Emailing the relevant listserv for articles that are unpublished is another good way to update your search and find relevant works. Plus, you are in a sense “marking your territory” for that topic so it lets other researchers avoid wasting their time conducting the same meta analysis. Conversely, emailing the listserv will tell you if someone else is already doing the meta analysis.<br />
<br />
<br />
<br />
== <center> Step 3 - Finding ES </center> == <br />
<br />
=== What to do about the issue of dependence of effect sizes? ===<br />
:Should you compute more than one ES per study? Best solution is to compute both ways. In some cases you might want to have data from same Ss be in two or more effect sizes. For example, if want to look at different types of DVs in relation to overall effect sizes, then if same Ss in same study filled out two or more DVs, then AFTER doing normal independent overall ES (where you only take 1 ES per study), do a second stage test of non-independence and coding more than one ES per Ss. (See Johnson and Eagely, 2000, page 519<br />
<br />
=== If only taking 1 ES per study, how to choose which one? ===<br />
:Either pick the one that is most common across the studies. Or, pick the average of the ES within the study.<br />
<br />
=== What if the primary study reports the effect size directly? ===<br />
:Should you use it, or should you try to compute the ES yourself based upon the statistical information from the article? First, try computing the ES yourself, and see how it compares to the ES reported in the study. Are they similar? However, keep in mind that some articles do not report enough statistical information to calculate the ES yourself, in which case you have to use the ES reported by the authors. Also, sometimes when computing the ES yourself from the statistical information in the article you encounter situations where you have imprecise statistical information, such as the authors reporting p < .05, in which you case must treat that as p = .05. In such a case, the ES you compute will be imprecise, and thus you may want to use the ES reported by the authors.<br />
<br />
<br />
<br />
== <center> Step 4 - Analyzing Data </center> == <br />
<br />
=== Should I use fixed or random? ===<br />
:Start by looking at the output for “fixed. If “random” is significant, then means that there is variation not explained by moderators.<br />
<br />
=== How to interpret the Effect Sizes? ===<br />
:See Johnson and Eagley (2000) Quantitative synthesis.. page 520. see also Lipsey and Wilson (2001) Practical meta-analysis, page 146-<br />
<br />
<br />
<br />
== <center> Step 5 - Moderators </center> ==<br />
<br />
=== How many moderators can I anlayze? ===<br />
:Meta is exploratory, so you can code for as many variables as you wish. Here is citation to support that statement (Guzzo, Jackson, and Katzell, 1987). Guzzo, R.A., Jackson, S.E., & Katzell, R. A. (1987). Meta-analysis analysis. In L. L. Cummings and B. M. Staw (eds.), Research in Organizational Behavior, Vol. 9, pp. 407-442. Greenwich, CT: JAI Press.<br />
<br />
=== Should the moderators be categorical or continuous? ===<br />
:Ideally, continuous. Why? Continuous scale ranges contain more data, so more power. Plus, you can convert a continuous variable into a categorical variable, but you can't do the reverse. Sometimes the variable itself dictates whether it is categorical or continuous. For example, gender as a moderating variable is categorical by design.<br />
<br />
=== Why should the coding sheet be in excel? ===<br />
:When creating the “coding sheet” that you give to coders and upon which they enter their codes, it is easiest for you if the coding sheet is an e-copy, such as excel, because the data is therefore already entered. <br />
<br />
=== Why would there be inconsistency in coders ratings? ===<br />
:Why would there be inconsistency? It may be a coding mistake. It may be because the coders are misunderstanding how to code the variable. You may want to have a third-party tie-breaker decide the issue. Try to not let the coder with the most dominant personality dictate how the issue is resolved. Some inconsistency is expected, which is why there are multiple coders.<br />
<br />
=== How to increase quality of coders/codings? === <br />
:Since coding can be boring, and there is a temptation to rush through the coding too quickly, impress upon the coder the seriousness of their impact on the study (because garbage-in garbage-out). You may also try impressing upon them the consequences of poor performance and how you are double checking their work (somehow?)</div>Doughttp://aggression.psychwiki.com/wiki/Analyzing_DataAnalyzing Data2016-11-22T02:34:36Z<p>Doug: </p>

<div>'''Descriptive Statistics''' are a group of procedures that summarize data graphically and statistically. Descriptive statistics are designed to describe a sample, and is contrasted with Inferential Statistics which is designed to draw conclusions from the sample to the larger population. [[Image:Fe40.png]] - Imagine you conduct a study to determine whether males or females are happier. After collecting data on 1000 subjects you could use "Descriptive Statistics" to identify characteristics of the sample, such as the mean happiness levels, ranges of scores, standard deviation, and so forth; and you could use "Inferential Statistics" to identify if your sample of data generalizes toward the larger population of males and females beyond those in your study.<br />
<br />
'''Inferential Statistics''' are designed to draw conclusions about a population from a sample of data, and is contrasted with Descriptive Statistics which is designed to describe only the sample. [[Image:Fe40.png]] - Imagine you conduct a study to determine whether males or females are happier. After collecting data on 1000 subjects you could use "Descriptive Statistics" to identify characteristics of the sample, such as the mean happiness levels, ranges of scores, standard deviation, and so forth; and you could use "Inferential Statistics" to identify if your sample of data generalizes toward the larger population of males and females beyond those in your study.<br />
<br />
<br />
<br />
'''What is the theory behind Inferential Statistics?''' If Inferential Statistics allow you to draw conclusions from a sample to the larger population, how do we know the conclusions are accurate? How researchers address that question is the heart of statistical reasoning: <br />
*We will never know with 100% confidence that the results of the study can generalize toward the intended population (unless and until we study the entire population) but we can determine the probability or percentage of our confidence in the accuracy of the study results by using probability distributions.<br />
*A probability distribution describes the frequency or probabilities that an event can take. [[Image:Fe40.png]] - If you flip a coin, there are two possible outcomes – Heads and Tails. So the probability of each one occurring is 1/2 or 50%. If you asked someone how likely it is that a flipped coin would come up heads, the answer is 50%. For a more complex example, think of a distribution of IQ scores. How likely is it that someone would score a 160? By using a probability distribution of IQ scores, such as the example one below, you could calculate the frequency of people who score 160 (or who score above 160, or who score below 80, and so forth). <center>[[Image:OUTPUT0.png|400px]]</center><br />
*Using probability distributions, statisticians have created a process for establishing the probability that the results from a sample are accurate of the population. Statisticians have created all possible probability distributions for every possible statistical situation. The process involves comparing your sample to the appropriate probability distribution. If there is a low probability that the results of your sample are due to chance, then we accept the results of the study as accurate to the population. <br />
*How low does the probability have to be? In the social sciences, researchers have agreed as a field upon a '''5% or less''' probability level. In other words, if there is less than a 5-percent probability that your results were due to chance, then we deem the results as "significant". Probability is written as "p", so significance is written as "p<u><</u>.05". <br />

<div>General tips...<br />
<br />
* Helpful to run data in multiple ways to look for converging evidence of your results. When inconsistencies arise, track down the source.<br />
<br />
* Its appropriate to test for simple effects even if no omnibus interaction.<br />
<br />
* Data analysis should be planned BEFORE the study is conducted so as to ensure that the methodological design of the study permits the type of data analysis of interest to the investigator.<br />
