Quizplus · Accepted Answer

Before selecting the appropriate test of significance, Cristos should first decide if he will be using a parametric or nonparametric test based on the distribution of the data and the level of measurement of the variables. Parametric tests assume the data is normally distributed and the variables are measured at a continuous or interval level, while nonparametric tests do not make these assumptions and can be used for ordinal or categorical data. Once this decision is made, Cristos can then move on to consider other factors such as power analysis, effect size, and level of significance to select the appropriate test.
