A) Present the frequence distribution of each of the variables WEIGHT, EDU, WAGE and FOODEXP in an appropriate vivid way.

WEIGHT To present the frequency of the quantitative variable WEIGHT, bins of 5kg have been created with Statplus for mack using statistics-basic statistics and tables-histogram and are shown in a bar graph.
