Question

|. Find the mean, median, and mode of the
following marks (in ascending order) secured by
16 students in a clase test of 10 marks.
0,0,2,2,3,3,3,4,5,5,5,5, 6, 6, 7,8​

Answer 1

Answer :- Mean = 6.4,  Mode = 5,  Median = 4.5

Step by step explanation :-

Finding Mean -  

Sum of observations/ No. of observations

0 + 0 + 2 + 2 + 3 + 3 + 3 + 4 + 5 + 5 + 5 + 5 + 6 + 6 + 7 + 8 / 10

= ​64/10

= 6.4

Finding Mode -

The most occured number = 5

Finding Median -

( Note :- if the sum of numbers are odd then the center number is median. if the sum of numbers is even then we have to add the two middle terms and divide by 2. )

Here, the set is even, so we have to add the two middle terms and divide by 2.

= 4 + 5 / 2

= 9/2

= 4.5

Answer 2

Answer:

Step-by-step explanation:

Solution :-

Mean = Sum of observations/ No. of observations

Mean =0 + 0 + 2 + 2 + 3 + 3 + 3 + 4 + 5 + 5 + 5 + 5 + 6 + 6 + 7 + 8 / 10

Mean = ​64/10

Mean = 6.4

Mode = The most occured number

Mode = 5

Median = Here, the set is even, so we have to add the two middle terms and divide by 2.

Median = 4 + 5 / 2

Median = 9/2

Median = 4.5
