Please note that my name is Ms. Sue.

Your first two answers are right. However, without commas or a list, I can't really determine what your problems are.

It looks as though you have the right idea for solving these mean and median problems.

3)there are two medians -2 and 3 , so the median is the mean of -2and 3, thats (-2+3)/2 = 1/2=0.5
mode is an average , you can not say there is no average for a given data , so here any value can be taken as the mode
8) the mean = -1.25
median = mean of -1 and 0= -1/2= -0.5
5) median = 72
and some more mistake are there i hope MARKO you will be able to correct it
bye :)
