Explanation / Answer

ok , we need to read the boxplots here to get the answers

a)the middle line in the box is the median in a box plot , which is 6 here

b) The upper and the lower quartile are given by the left and the right boundaries of the box plot

hence lower quartile = 5

Upper quartile = 8

c) The IQR of the data is the difference between the upper quartile and the lower quartile , or the space between the outer boundaries of the region

hence 8 - 5 = 3 , is the IQR

d) If the median is in the exact middle of the box then the data is not skewed . If it is towards the left then the data is right skewed , if the middle line is towards the right , then the data is left skewed . So correct naswer is a
