Another of the researcher’s questions involved the difference in scores on the Asking for Help subscale based on the respondents’ reported number of online courses completed. Use SPSS to conduct the analysis that is appropriate for this research question and answer each of the questions. If a statistical significance test is used, you should use .05 as the critical level of significance.

Anxiety associated with asking for help during a statistics course
Questions:
1. Based on the scenario, what is the appropriate analysis for examining differences among the Asking for Help subscale scores based on the number of online courses completed?
2. Based on the results of the Scheffe post hoc test, which groups are significantly different?
3. Present the results as they might appear in an article. This must include a table that reports the results of the analysis and narrative statement that reports and interprets the results of the analysis and Scheffe post hoc test.

Explanation / Answer
1. Based on the scenario, what is the appropriate analysis for examining differences among the Asking for Help subscale scores based on the number of online courses completed?
Solution:
Here, we have to use the one way analysis of the variances or ANOVA test for examining the differences among the asking for help subscale scores based on the factor number of online courses completed. The descriptive statistics and ANOVA table for this test by using SPSS is given as below:
Descriptive Statistics

The p-value for the above ANOVA table is given as 0.001 which is less than the given level of significance or alpha value 0.05, so we reject the null hypothesis that there is no any significant differences in the help subscale scores based on the factor number of online courses completed. This means, there is sufficient evidence to conclude that there is a significant differences in the help subscale scores based on the factor number of online courses completed.
2. Based on the results of the Scheffe post hoc test, which groups are significantly different?
Solution:
The SPSS output for the Scheffe post hoc test is given below for checking the significant differences in the help subscale scores as per given number of online courses completed.

Means for groups in homogeneous subsets are displayed.
a. Uses Harmonic Mean Sample Size = 30.000.
There is no significant difference in the help subscale scores for the 3 to 7 online courses completed and 8 or more online course completed. All other differences in the help subscale scores are statistically significant.
3. Present the results as they might appear in an article. This must include a table that reports the results of the analysis and narrative statement that reports and interprets the results of the analysis and Scheffe post hoc test.
Solution:
According to the ANOVA test for comparing the help subscale scores for the different number of online courses completed, we found the significant p-value as 0.001. so we reject the null hypothesis that there is no any significant differences in the help subscale scores based on the factor number of online courses completed. This means, there is sufficient evidence to conclude that there is a significant differences in the help subscale scores based on the factor number of online courses completed. The results are given in the following table:

Also, according to Scheffe post hoc test, there is no significant difference in the help subscale scores for the 3 to 7 online courses completed and 8 or more online course completed. All other differences in the help subscale scores are statistically significant.
