Construct a cumulative relative frequency plot, Basic Statistics

Examine the distributions of weight and height. Are there any outliers? If so deal with them appropriately.

Create a new variable that divides weight into groups. Produce a table showing the frequency distribution and cumulative relative frequency distribution of the new grouped variable. Produce a histogram of weight to illustrate this frequency distribution and comment on the histogram.

Construct a cumulative relative frequency plot (by hand or otherwise) of the new variable and use it to estimate the median weight. Why may this estimate differ from the median of the recorded values for weight? Which estimate would be preferred and why?
