#### The distribution of heights (in cm) of 96 children is given below :                Height (in cm) Number of children 124-128 128-132 132-136 136-140 140-144 144-148 148-152 152-156 156-160 160-164 5 8 17 24 16 12 6 4 3 1 Draw a less than type cumulative frequency curve for this data and use it to compute median height of the children.

Solution.

 Height Number of children less than 124 less than 128 less than  132 less than 136 less than  140 less than  144 less than  148 less than  152 less than  156 less than  160 less than  164 0 5 13 30 54 70 82 88 92 95 96

$\frac{n}{2}= \frac{96}{2}= 48$
Hence the median is = 139
