Question

I cannot understand this can you guys help

A student points for a test in a lower math class were 85,81,87,78. what is the student mean & median test points
Mean is
Median

Answer 1

the mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median
