In his famous 1938 text, the so-called "Columbia bible," R. S. Woodworth
Distinguished between independent and dependent variables in experiments

PREDICTION
Also called regression
Mathematical rules constructed to predict peoples
scores on one variable from knowledge of their score on
another variable (predicting college grades from SAT
scores)

ONE-WAY ANOVA
SOME BACKGROUND
INFORMATION
ANOVA = Analysis of Variance
Variance = tells us how much variability there is around the mean
Higher variance = more variability within a dataset
Can affect the outcome of a statistical procedure as well

How can a group of scores be summarized in a single
number?
Symbols to keep in mind:
N = Number of subjects in a population
n = Number of subjects in a sample
M = Mean (average) of a sample; c

INFERENTIAL STATISTICS
Involves making inferences about populations based on
information from samples
Remember, descriptive statistics just summarize known
information
Why are inferential statistics important?
