- Below is the question I am having a problem with as well as the portion of the answer I have come up with. I do not know if I am right or not, but I need an explanation to understand this, please. What information does the F ratio on the SPSS output for an independent sample T test provide? That is, what assumption does it test. A researcher might use the independent sample t test when he assumes that there will be equal mean populations between to variances. To calculate the independent sample t test, one would use this formula: t = m1-m2 SEm1-m2Using the following table: 1. Determine a hypothesis to test the relationship between students enrolled 12 months or less and sleep of students, use descriptive statistics to describe the variables both numerically and graphically, identify the appropriate type of statistical test using alpha = 0.05, perform the statistical test (please show steps).
