TS EAMCET 6-Aug-2021 Shift 1 Question Paper

Given data in ascending order is 4,4,7,12, 14,15,15,23
Here, number of terms, n=8, which is even. So, median
‌‌=‌

( n 2 )‌ th term ‌+( n 1 +1)‌ th term ‌

2

‌‌=‌

4‌ th term ‌+5‌ th term ‌

2

=‌

12+14

2

=13
Calculation of mean deviation about median

xi	|di|=|xi−13|
4	9
4	9
7	6
12	1
14	1
15	2
15	2
23	10

∑|di|=40
Hence, mean deviation about median
=‌

∑|di|

n

=‌

40
