Explanation / Answer

Solution:- Scatter method is superior than the Bar method.

The bar chart is particularly appropriate for displaying discrete data with only a few categories, as in our example of BMI among the freshman class.

So in this question we have continuous data so scatter plot is more appropriate as comparative to bar charts.
