Question

The distribution of heights (in cm) of 96 children is given below. Construct a histogram
a)what is the class width ?

Answer 1

Answer:

To draw the less than type ogive, we plot the points (124,0), (128,5), (132,13), (136,30), (140,54), (144, 70), (148, 82), (152, 92), (160, 95), (164, 96), (164, 96) and join all these point by free hand. Here, N/2 = 96/2 = 48 We take, y = 48 in y - coordinate and draw a line parallel to X - axis, meets the curve at A and draw a perpendicular line from point A to the X - axis and this line meets the X - axis at the point which is the median = 141.17Read more on Sarthaks.com - https://www.sarthaks.com/889279/the-distribution-of-heights-in-cm-of-96-children-is-given-below
