Question
As an international development researcher, you have already tested whether perceptions about the current levels of democracy differ from a value of 6. Given recent social change mo vements in North Africa, you now want t o determine whether there is a statistical difference in these perceptions between North Africa and Southern Africa. Using the data from the 2015 Afrobarometer , p lease provide: a 1 – 2 APA style paragraph statement that furnishes an answer to this question, note the relevant statistics, comment on meaningfulness , and include your relevant SPSS output.
Explanation / Answer
This study will formulate both the null hypothesis and the alternative hypothesis that will be used in this study to come up with a conclusion and comment about the said claim of interest. Therefore, the null hypothesis and the alternative hypothesis will be,
The current levels of democracy differs from the value of 6
The current levels of democracy does not differs from the value of 6
From this context, we will carry out the analysis of variance in order to come up with a conclusion whether there exist a significant difference in the levels of democracy between North Africa and South Africa. The anova table is as below,

The independent sample t-test is the best t-test approach that can be used in this scenario as you are able to see if there is any normality that isoccurring. From the above table, we can see that the f value is greater than the critical, value and therefore, we fail to reject the null hypothesis and conclude that there is no significant difference at level of significance. This therefore implies that the levels of democracy between the North Africa and the South Africa do not differ.
