Final Answer :
C
Explanation :
Inferential statistics provide a way to determine the likelihood of obtaining an observed difference between two research samples by chance. This allows us to determine the significance of the difference and make conclusions about the population from which the samples were drawn. Skewed distributions, percentile scores, and bar graphs do not provide this level of statistical analysis.
