Question

9) The marks in maths of 12 students of class VII are given below.
29,20,22,30,29,27,25,26,29,21,22,19. Find
(i) Range of data (ii) Median
(iii) Mode
(iv) Mean of the Median and Mode

Answer 1

Answer:

Answer is given below....

Step-by-step explanation:

(i) Range = maximum value - minimum value

maximum value= 30-19 = 11

(ii) Median = for median order the smallest number from highest number.then find the middle number.

19,20,21,22,22,25,26,27,29,29,29,30

median =25 and 26

(iii) Mode = number which is repeated Moro times,in this 29 is repeated three times and 22is repeated two times, so mode is 29.

(iv) Mean = sum of observation ÷ number of observation

so sum of observation = 299

number of observation = 12

=24.9
