why is the median net worth a more useful measure than the average net worth.

Question

this is the answer i put:

Median net worth is a more useful measure than the average networth because its gives you the exact number quality total of each product we are graphing. But the average will provide us information of the total divided by the amount of the products and not the exact amount. When graphing, it is easier to compare when you have the exacts amount for each product than the average net worth.
