Lecture 12
Two-way ANOVA
We have discussed experiments with one independent
variable
Experiments can have multiple independent variables,
allowing us to simultaneously examine:
The effect of each IV, independent of other variables
Analysis of variance
(ANOVA)
Lecture 11
Comparing means
Testing single sample mean: z test or t-test
Comparing means of 2 groups: related-samples t-test or
independent-samples t-test
What if we want to run an experiment where we compare means for
more
Single-sample tests
Lecture 9
Sampling distributions
We evaluate the probability of obtaining a score from an
underlying sampling distribution
Sampling distribution assumes the H0 is true
Recall logic of hypothesis test: need to know probability

BINOMIAL EXPERIMENTS
Binomial distribution
A binomial experiment is one that meets all of the
following requirements:
1. The experiment must have a fixed number of
trials.
2. The trials must be independent.
3. Each trial must have all outcomes classified
