Regression |
look at the ability for the IV to predict the DV |
|
|
R2 |
variance accounted for |
|
|
T-Test (t) |
nominal variable of 2 categories -Outcome (DV) is interval or ratio level variable |
|
|
ANOVA (F) |
nominal variable of 3 or more categories -Outcome (DV) is interval or ratio level variable |
|
|

a systematic, replicable technique for compressing many words of text into fewer content categories |
|
|
"N" |
people in the sample |
|
|
degrees of freedom |
amount of variables that are allowed to vary ex.) sample minus the number of variables you're looking at -> (N-2) |
|
|
Chi-Square |
2 nominal level variables |
|
|

odds between 2 nominal variables |
|
|
Spearman's Rho |
2 ordinal level variables |
|
|
reporting a correlation |
r(324)= -0.50, p<0.05 R2= 0.25 "r"- correlation/test we run "p<0.05"- significant bc its less than .05 "R2"- square the -0.50 |
|
|
T-tests use IV's of ___ level of measure, and DV's of ___ level of measure. |
nominal ; interval/ratio |
|
|
ANOVAS use IV's of ___ level of measure, and DV's of ___ level of measure. |
nominal ; interval/ratio |
|
|
Descriptive |
Describes the sample. -uses measures of central tendency ex.) mean, med., mode |
|
|
What statistical test uses 2 interval/ratio level variables, measures the degree to which the 2 variables are related, and is represented by an "r" value? |
Pearson Correlation |
|
|
What statistical test uses 2 interval/ratio level variables, uses the IV to predict the DV, is represented by "R," provides you immediately with an R2 value, and measures the change in the DV brought on by the change in the IV? |
Regression |
