Compute the independent samples t on the data set below. Assume a standard deviation of 1.67 for Condition 1 and 1.92 for Condition 2, a two-tailed test, and an alpha level of .05. What is tobt?

Condition 1 Condition 2
8 3
6 2
10 5
7 7
6 4

Answer #1



Since the p-value is less than the 0.05 alpha level, we reject the null hypothesis of the non-significant difference between the two samples. We conclude that there is enough evidence to suggest that there is a significant difference between the two samples.

1. A researcher is comparing scores from two treatment groups using independent samples t test. Use a Hartley’s F-max 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?
