You need to remember that the mean is equal to median if the distribution is symmetrical.

The graph has a bell shape and the portions above and below a fixed point (vertex of the bell) are mirror images.

For the numbers you've given, the mean is:

mean = (2+3+5+7+8)/5 = 25/5 = 5

median = the middle number of the five given values = 5

ANSWER: The median=mean=5, therefore you may obtain a symmetric distribution of the numbers.

Just add another 5 in the middle



5 +5=10/2=5

mean= 2+3+5+5+7+8=30/6=5

mode=5 because it appears the most
