Abbreviated as EFA.
What is [the abbreviation for] Exploratory Factor Analysis?
100
This individual, former head brewer of the Guinness Brewing Company, came up with a statistic. Guinness wouldn't allow employees to publish, so he published under the pseudonym "student."
Who is William Gossett
100
This statistical test works best with normally distributed data. It works by comparing two continuous means.
What is the t-test
100
This assumption is often tested using the histogram with this specific curve. 
What is the normal distribution?

N
What is [the symbols for] sample size?
200
Abbreviated as CFA.
What is [the abbreviation for] Confirmatory Factor Analysis
200
Ensures that results obtained from your sample should approximate what would have been obtained if the entire population had been measured.
What is random sampling?

X̄ or M
What is [the symbol for] sample mean?
300
Abbreviated as MLM
What is [the abbreviation for] Multi Level Modeling

μ
What is [the symbol for] population mean?
300
Rejecting the null hypothesis when it is in fact true.
What is a Type 1 Error?
400
Abbreviated as GLMM
What is [the abbreviation for] Generalized Linear Mixture Models.
400
This statistician, who wrote about "Statistics and Causal Inference," learned to play banjo from Jerry Garcia of the Grateful Dead.
Who is Paul Holland?
400
Helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment. Thus, any differences between groups recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment. Hint: the opposite of placing participants in a specific group.
What is random assignment?

What is [the symbol for] sample variance?
400
Not rejecting the null hypothesis when in fact the alternate hypothesis is true
What is a Type II error?
500
Abbreviated as LCGA
What is [the abbreviation for] latent class growth analysis?
500
This psychologist was to receive a lifetime achievement award from the American Psychological Association before they withdrew it at the last minute after realizing he was supported a eugenicist movement called "beyondism."
Who is Raymond Cattell, inventor of the scree plot.
500
Underlies both t-test and F tests. The distribution, or “spread,” of scores around the mean of two or more samples are considered equal.
What is homogeneity of variance or Heteroskedasticity ?
500
r
What is [the symbol for] linear correlation coefficient?
600
Abbreviated as MSEM
What is [the abbreviation for] multilevel structural equation modeling?
600
This statistician coined the term "bit" that is commonly used in computer science to describe "binary digits," as well as having the earlies known usage of the term "software."
Who is John Tukey?
600
A type of discrete time structural equation model used to analyze panel data in which two or more variables are repeatedly measured at two or more different time points. This model aims to estimate the directional effects that one variable has on another at different points in time. Here is a drawing
What is a cross lag panel model?
600
The occurrence of high intercorrelations among two or more independent variables in a multiple regression model
What is multicollinearity?

σ2
What is [the symbol for] population variance?
700
Abbreviated as LTA
Latent Transition Analysis
700
This statistician told the military during World War II that they should reinforce areas of planes that had no holes rather than those that did as the military was previously doing. He argued that the area that being shot in the areas that had holes did not cause planes to fall from the sky, whereas being shot in other areas did, thus illustrating one of the first named cognitive biases.
Who is Abraham Wald?
700
The condition where the variances of the differences between all combinations of related groups (levels) are equal. Particularly important for ANOVAs with repeated measures (within-subject factors).
Hint: Mauchly was really worried about this.
What is sphericity?

η2
What is an effect size for the Analysis of Variance?
700
I am a researcher who published an article stating that most published research findings are false. I am really interested in the replication crisis.
Hint: I share my first name with. Dr. Calamari.
