Before selecting a statistical procedure for a dataset, we need to be clear with the parameter we need to analyze and develop the hypotheses corresponding to them. This will help us narrow down our choices based on the sampling distribution of the dataset provided to us. The narrowing down of options might include whether to use a parametric test or non-parametric test and can further narrow down according to the categorical and continuous variables.
Thus, Option A. is correct.
