Question

Quizplus · Accepted Answer

Parametric statistical tests assume a specific distribution of scores, usually a normal distribution. Nonparametric tests do not require assumptions about the distribution of scores. Robust statistics refer to methods that are not sensitive to outliers or violations of assumptions, while distributional statistics focus on the shape of the distribution of the data. Therefore, C (parametric) is the correct answer.
