Mean = 630/10 = 63
Median = (60+50)/2 = 55
scores greater than 55 but less than 63, There is only one score i.e. 60
Hence answer is 1.

Mean is just adding the numbers and dividing by the total number of numbers present
Mean = 630/10 = 63
Median
Always arrange the numbers in order(ascending if thats easier)
before you find the median. This problem gives the numbers in ascending order already One less thing to do
Case 1: If the total number of numbers is even(like this case)
Median = average of the middle 2 terms
40,45,45,50,50,60,70,75,95,100
Median = 50+60/2 = 52
We have already found the mean to be 63
>52 <63 in the list is just one which is 60
Case2: If the total number of numbers is odd this case)
Let say 1,2,3 for example
Median is 2(middle number in the arranged order)
Hope this helps!
