Answer 2

Step-by-step explanation:

Mean

mean =∑x/N

Here,

∑ represents the summation

X represents observations

N represents the number of observations .

mean = 13+14+15+13+15+14+13+13+15/ 9

= 125/9

= 13.89

Median

arrange given observations in ascending order

13,13,13,13,14,14,15,15,15

If the total number of observations (n) is an odd number, then the formula is given below:

Median=(n+1/2) th observation

= 9 + 1 / 2

= 10/ 2

=5 th

5th observation is 14. this is median of data.

Mode

The mode is the most frequently occuring observation or value.

mode = 13
