As part of a larger study, Dana collected data from 20 college students on their emotional responses to classical music. Students listened to two 30-second segments from “The Collection from the Best of Classical Music.” After listening to a segment, students rated it on a scale from 1 to 10, with 1 indicating “Makes me very sad” and 10 indicating “Makes me very happy.” Dana computes a total score (hap_sad) for each student by summing the student’s two ratings. Dana conducts a one-sample t test to evaluate whether classical music makes students sad or happy.

Conduct the analysis of these data, and write the results section for it. Make sure to include some descriptive statistics (i.e. mean and SD).

PS: There is no prior mean or population mean given to compare to so you should use the value of 11 which is the median of the possible scoring values. A score of 11 would equate to an average of the 2 scores and would represent neither sad nor happy from a combination of the two music pieces. The midpoint of 1 to 10 = 5.5 to represent the Ho. Since we summed up values of 2 test scores, the midpoint = 5.5*2 = 11.

Here is the SPSS output from the data.
