Sample size helps determine the size and probability of obtaining better statistical significance given the value of P of less or equal to the rationally set value.

Since the one-sample t-test determined statistical difference between citizens’ perceptions about the present state of democracy to differ from a value of 6, we can further compare and contrast perceptions between North Africa and Southern Africa. Using the 2015 Afrobaromater, we can use independent-samples t-test to associate means for two groups of subjects. In this […]
