horizontal axis
ordinate
IV
abscissa
11
P = .05 really means that
five subjects were not included in the study
no significance level has been set
the significance level is .01
5% chance: difference between control & experimental group due to chance
12
When a researcher wants to measure one variable at 3+ levels, what statistical measure is most appropriate?
Factorial ANOVA
MANOVA
One-way ANOVA
ANCOVA

A researcher wants to run a true experiment but will not use a random sample. You could safely say that
she could accomplish this using systematic sampling
her research will be correlational
she absolutely cannot run a true experiment
her research will absolutely be causal comparative research
21
If a researcher changes the significance level from .05 to .001, then
alpha errors increase but beta errors decrease
there's no impact on alpha or beta errors
alpha errors decrease but beta errors increase
alpha and beta errors will increase
22
The Kruskal-Wallis test is used when
you collect data from 2 independent samples and scores aren't evenly spread
you have nominal data that don't fall along a normal curve
you have scores for 2 samples and the scores are correlated
you have more than 2 mean scores on a single variable
23
