In this case, does the median represent the heights of the families. Class 7
Question 1.
In this case, does the median represent the heights of the families better than the average? Class 7
Solution:
No. Because the height of one member is very high.
Question 2.
Find the mean and median in Poovizhi’s data without the outlier value 118. What change do you notice? Class 7
Solution:
Without 118, the data is :
165, 170, 173, 175
So, mean = [latex]\frac {165+170+173+175}{4}[/latex]
= [latex]\frac {683}{4}[/latex] = 170.75
Median = [latex]\frac {170+173}{2}[/latex] = [latex]\frac {343}{2}[/latex] = 171.5
They are nearly the same.
