The mean is 70/7, the sum over the number=10
The mode is the most common, also 10.
The median is the middle of this ordered set=10
mid range is the mean of the largest and the smallest, and that is 19/2=9.5

given nos are 7,9,10,10,10,12,12
sum = 7+9+10+10+10+12+12
=70
no of numbers =7
mean = sum / no of numbers
= 70/7
=10
Mean =10
middle no of the above series = 10
so median = 10
mode = the no which repeated most no of times
= 10
mid range = mean of max and min values
=
=
= 9.5
Mid range = 9.5
