- Three groups of students involved in the same curriculum are obliged to study for 15 minutes, 30 minutes, or 90 minutes a night for 8 weeks before taking a mathematics test. Their scores are as follows:
15 Minutes: 43, 39, 55, 56, 73
30 Minutes: 55, 58, 66, 79, 82
90 Minutes: 61, 66, 85, 86, 91
-
- Are the differences statistically significant? (You MUST show the F-value and write up as your evidence. Do not simply reply yes or no)
-
- If the F is significant, which group(s) is(are) significantly different from which? (Again, you must show the significant post hoc value as evidence)
-
- How much of the difference in mathematics performance can be explained by how long students study?

A study was designed to compare the attitudes of two groups of
nursing students towards computers. Group 1 had previously taken a
statistical methods course that involved significant computer
interaction. Group 2 had taken a statistic methods course that did
not use computers. The students' attitudes were measured by
administering the Computer Anxiety Rating Scale (CARS). A random
sample of 11 nursing students from Group 1 resulted in a mean score
of 56.1 with a standard deviation of 5.5 A...
