Maria used a non-parametric analysis to analyze survey responses on a Likert scale. What does this imply?
A) Mariah is treating the data from Likert scales to be on an ordinal scale.
B) Maria is using tests like ANOVA to compare mean differences on Likert scales.
C) Mariah is wrong - Likert scales should always be analyzed on an interval scale, and she should use parametric methods.
D) None of the above are correct.

Non-parametric tests are used when the assumptions of parametric tests cannot be met. Likert scales are considered ordinal data, meaning that they have a ranking order but do not have a consistent distance between response options, which violates the assumptions of interval data required for parametric tests. Therefore, non-parametric methods, which do not rely on assumptions about the distribution of the data, are more appropriate for analyzing survey responses on a Likert scale.
