Question

(50 points) (with explanation)
find the mean of following data. 80,85,100,60,71,90

Answer 1

to find mean we have to add up all the numbers and divide by the number of values....so 1st we will add up 85+80+100+60+71+90=486...now u have six values ie 80(1)....85 (2)...100(3)....60(4)....71 (5)...90 (6)....now we have to divide 486 by 6..ie 486÷6 we get 81!! hence the mean of 80,85,100,60,71,90 is 81....hope this helped pl mark as brainliest

Answer 2

Hello !!

Here is your answer!


Formula for calculating mean -

Sum of observations/ total number of observations

So,


85+80+100+60+71+90=4n

You have given
six values ie
80(1)
85 (2)
100(3)
60(4)
71 (5)
90 (6)

Now we will divide 486 by 6..ie 486÷6 we get 81! hence the mean of 80,85,100,60,71,90 is 81.


Answer - Mean of observations is

81
