When data for two samples relates to the same group of respondents, it is best to use paired samples, making choice C the correct answer. This allows for the comparison of the same individuals before and after an intervention, treatment, or exposure, which can help control for individual differences and increase the statistical power of the analysis. Univariate techniques are used for analyzing a single variable, which can be either metric (measured on a numerical scale) or nonmetric (categorical or qualitative data). However, the fact that the data comes from the same group of respondents does not necessarily mean that the samples are dependent, as the data can be collected at different times or under different conditions. Therefore, the best choice is to use paired samples, which are dependent by definition.
