Question

find the following observations. 17,10,18,22,13,26,9,13,19

please answer me fast​

Answer 1

Answer:

Therefore , the total observations are 147

__

9

Step-by-step explanation:

Total number given = 9

Observation = Total no ÷ by Total given no

= 17 + 10 +18 +22+ 13 +26 +9+ 13+ 19

___________________________

9

= 147

___

9

Answer 2

Mean=16.33

Mode=13

Median=17

Mean=addition or all observations/Total no of

observations

Mode=The number which comes maximum times

in given observation

Mode = Firstly we have to arrange all the

observations in ascendung order and

calculate the number of observations if

number of observations is odd then the

formula is (n+1)/2 where n=number of

observations and if the number of

observations is even then formula

we uses is (n/2)+(n+1)/2 whole upon 2

But for median please arrange all the observayions in ascending order otherwise u will get wrong answer

and after applying formula the number which comes as your answer start counting your observation and suppose if your (n+1)/2=5 then the observation on number 5 will be your median

Hope it will helps you...
