Analyze why there are two different versions of the t test on the SPSS printout and how you decide which one is more appropriate.

Solution

1. One Sample t Tests,

One sample t-tests can be used to determine if the mean of a sample is different from a particular value.

2.Independent Sample Tests.

Sometimes you want to perform a t-test but the groups are defined by a variable that is not dichotomous (i.e., it has more than two values.) For example, you may want to see if the number of older siblings is different for students who have higher GPAs than for students who have lower GPAs. Since there is no single value of GPA that specifies \"higher\" or \"lower\", we cannot proceed exactly as we did before. Before proceeding, decide which value you will use to divide the GPAs into the higher and lower groups.
