Question

write in ascending order :- 28, 35, 32, 26, 27, 35, 36, 28, 29, 32, 37, 24, 33, 26, 25, 31, 22, 36, 27​

Answer 1

Rearranging the data into ascending order, we get
17,18,23,25,29,31,35,35,35,37,38,42

Here,
(a) Range = greatest observation − lowest observation
=42−17=25

(b) Mean = Sum of observations ÷ number of observations
=
12
17+18+23+25+29+31+35+35+35+37+38+42
​

=
12
365
​
=30.41

(c) Since the total number of observations is even
Median =
2
31+35
​
=
2
66
​

=33

(d) The mode is 35 because it occurs most frequently i.e., 3 times
