Answer -

To find the mean deviation from the median, firstly let uscalculate the median.

We know, Median is the Middle term,

So, Median = 61

Let xi =Heights in inches

And, fi = Number of students

xi

fi

Cumulative Frequency

|di| = |xi – M|

= |xi – 61|

fi |di|

N = 197

Total = 336

N=197

MD=

= 1/197 × 336

= 1.70

Themean deviation is 1.70.
