Question

find the range ,median and mode of given data. 31,37,29,41,35,38,44,32,29,36 and 29​

Answer 1

31,37,35,38,42,23,17,18,35,25,35,29

For the given data, find the

(a) Range (b) Mean (c) Median (d) Mode

Medium

Answer

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.

Answer 2

Answer:

range is 44-29= 15

median is (31+37+29+41+35+38+44+32+29+36+29)/11= 381/11=34 7/11

mode is 29
