Question

Using SPSS Find the: Test statistic, critical value, P Value, and state your conclusion. Create a Ho and a Ha.

Two different groups of 15 students were given two types of music while they worked on a quiz. Group A was given Type 1 musics and Group B was given Type 2 music. Scores on the quiz were recorded. Based on the results, is there evident of a significant different between the two types of music and the effect on the quiz performance.

Group A 26,21,22,26,19,22,26,25,24,21,23,23,18,29,22

Group B 18,23,21,20,20,29,20,16,20,26,24,25,17,18,19

( I need help also a detailed explaination of what tests to run is ssps and how to do it.)

Answer 1

This is an Independent Samples t-test.

Enter the data into SPSS.

Name the variables.

Go to Group variable values and name the groups.

Enter Value = 1 & Label = Group A.

Enter Value = 2 & Label = Group B.

Go to the Independent-Samples T Test.

Go to Define Groups.

Click Continue and click OK.

The output is:

The hypothesis being tested is:

H₀: µ₁ = µ₂

H₁: µ₁ ≠ µ₂

The test statistic is 1.716.

The df is 26.774.

The critical value is 2.056.

The P-value is 0.098.

Since the p-value (0.098) is greater than the significance level (0.05), we cannot reject the null hypothesis.

Therefore, we cannot conclude that there is a significant difference between the two types of music and the effect on quiz performance.
