Final Project Scenario

A researcher has administered an anxiety survey to students enrolled in graduate level statistics courses. The survey included three subscales related to statistics anxiety: (a) interpretation anxiety, (b) test anxiety, and (c) fear of asking for help. The survey also included three subscales related to attitude toward statistics. For the items that comprised the scales, students were asked to respond using a 5 point likert-type scale. Higher scores on the anxiety subscales implied higher levels of anxiety, and higher scores on the attitude subscales implies a more positive attitude toward statistics.

In addition to the statistics anxiety subscales, the survey contained a subscale related to the use of statistical software and a subscale related to self-perceived confidence concerning general computer use. Students responded to items on the statistical software subscale using a response range from (1) Strongly Disagree to (7) Strongly Agree. For the computer confidence subscale, students responded to items using a range from (1) Strongly Disagree to (5) Strongly Agree. For each of these subscales, higher scores implied higher levels of confidence.

The researcher determined the score for each subscale by computing the mean response for the items associated with the subscale. This technique resulted in subscales that had the same possible range and the items that made up the subscale.

A subsample of the researcher's dataset contains the following variables that should be used for completing the four final projects. The variables included in the dataset are:

Final Project 1

One of the researcher's questions involved the difference between males and females on the Test and Class Anxiety subscale. Use SPSS to conduct the analysis that is appropriate for this research question and answer each of the following questions. If a statistical significance test is used, you should use .05 as the critical level of significance.
