A researcher calculates an F-ratio comparing the GPAs of three different SJSU majors: Major A (M = 2.70) , Major B (M = 2.87) and Major C (M = 3.01) . If she makes the decision to NOT reject the null hypothesis, what is the most specific and appropriate conclusion she can draw?
A) The SAT scores for the three groups are all different from each other.
B) The analysis supports the research hypothesis.
C) The GPAs of the three majors are not significantly different.
D) No conclusion can be determined without conducting further analyses.
Null Hypothesis
The default hypothesis that there is no significant difference or relationship between specified populations, any observed effect is due to sampling or experimental error.
GPAs
Grade point averages, numerical calculations that represent the average performance of a student across all completed courses.
F-ratio
A statistical measure that is used to compare the variance among group means in a sample.
