Show answer & explanation
Correct answer: B
Parametric tests require specific conditions to be met for valid analysis. The data should follow a normal distribution (Option B). Additionally, the dependent variable must be measured on an interval or ratio scale (Option D), and there should be homogeneity of variance across groups (Option E). Option C is incorrect because parametric tests estimate population parameters rather than requiring them to be known beforehand.
