Problem #3
1) Conduct a relatedsample ttest using the following data set.
Each row represents a pair of scores.
A: 18, 35, 31, 30, 40, 25, 11, 30, 28, 20
B: 4, 40, 13, 18, 30, 27, 17, 18, 12, 20

2) Determine the critical values (for an alpha of .05) that you
should use to evaluate this tscore.

3) Compute r2 for this ttest.

1. A researcher is comparing scores from two treatment groups
using independent samples t test. Use a Hartley’s
Fmax test to examine this assumption (each group has 6
participants, s2 in group 1 is 20, and s2 in
group 2 is 15, set alpha level at .05). Also, how should this
researcher estimate the standard error in the independent samples
t test?

samples, 1way ANOVA

Researchers wanted to explore different treatment methods to
effect memory skills in high school freshmen. Subjects were given a
memory test (under multiple conditions) these were the results:
Group 1
10, 8, 9, 11,
8, 9, 7, 6,
9, 8
Group 2
12, 10,
11, 9, 13, 8, 9, 12, 11, 11
