Question

Following are the observation of throwing a dice 15 times
5, 3, 4, 1, 6, 2, 2, 4, 3, 2, 1, 5, 1, 6, 2
Find the mean, mode and median of this data,​

Answer 1

Answer:

Rearranging the data into ascending order, we get

1,1,1,2,2,2,2,3,3,4,4,5,5,6,6

We know that,

Mean=

number of observations

sum of observations

⇒ Mean=

15

1+1+1+2+2+2+3+3+4+4+5+5+6+6

=

15

47

=3.13

Now, total number of observations =15, which is odd.

∴ Median =8

th

term =3

Now, the observation 2 occurs the most i.e., 4 times

∴ Mode =2

Hence, Mean =3.13, Median =3 and Mode=2

Answer 2

Given : observation of throwing a dice 15 times

5, 3, 4, 1, 6, 2, 2, 4, 3, 2, 1, 5, 1, 6, 2

To Find :  mean, mode and median of this data,​

Solution:

5, 3, 4, 1, 6, 2, 2, 4, 3, 2, 1, 5, 1, 6, 2

arranging data in order

1  1  1  2  2  2 2 3  3 4 4 5 5 6 6

there are total 15 datas hence 8th data will be median

Hence 3 is the MEDIAN

2 has maximum frequency as 4

so 2 is the MODE

Mean = (1 + 1 + 1 +2 + 2 + 2 + 2+ 3 + 3 +4 + 4 + 5 + 5 + 6 + 6)/15

= 47/15

= 3.13

Mean is 3.13
