Instructions: Please enter the data below into SPSS and calculate a one-sample t-test for the two (both) scenarios below.  

1.    SPSS Scenario: A group of health researchers wanted to evaluate the anxiety levels of college students. Scores on the Beck Anxiety Inventory can range from 0 to 63. The scores below are from the Beck Anxiety Inventory on the same 10 individuals included in the study above. The population mean is 42.

2.    SPSS Scenario: A group of health researchers wanted to understand the inner strength of college students who were diagnosed with anxiety. The Inner Strength Questionnaire (ISQ) developed by Roux, Lewis, and Dingley (2004) was administered through an online survey system to a sample of 248 students studying at a mid-size university. The scores on the ISQ range from 0 to 27 (0 is no inner strength). The scores of 25 of the students are listed below. The population mean is 19.

Answer 1

I have attached a video on using JASP, an SPSS like free program, to show how to do a one sample t test based on a column of data.

The results for the first sample, with a test mean of 42 is as follows

t df p-val

1.611 9 0.142

We do not reject the null Hypothesis that there is no difference between the

sample mean and the given test mean of 42

The results for the second sample for ISQ scores, with a test mean of 19 is as follows

t df p-val

-1.685 9 0.126

We do not reject the null Hypothesis that there is no difference between the

sample mean and the given test mean of 42
