The Independent Samples t-Test compares the means of two
independent groups to determine whether there is statistical
evidence that the associated population means are significantly
different. The Independent Samples t-Test is a parametric test.
Give an example of two variables you would compare, what your
theory is and the hypothesis, and how you would find the
independent samples t-test in SPSS.

Problem 1: Independent Samples T In a study of jury behavior,
two samples of participants were provided details about a trial in
which the defendant was obviously guilty. Both groups received
common details. However, group two was also told that some evidence
had been withheld from the jury by the judge. Participants were
asked to recommend a sentence. The table below summarizes the
average sentence (in years) for each group. Is there a difference
in recommended sentence between the two...

Chapter 10) Several factors influence the value obtained for the
independent-measures t statistic. Some factors affect the numerator
of the t statistic and others influence the size of the estimated
standard error in the denominator. For each of the following,
indicate whether the factor influences the numerator or denominator
of the t statistic and determine whether the effect would be to
increase the value of t (farther from zero) or decrease the value
of t (closer to zero). In each...
