Question

Find the MEAN, MEDIAN and MODE of the following numbers:
40 61 95 79 9 50 80 63 109 42

Answer 1

Answer:

hey your answer is as follows

so pls mark it as brainliest

Step-by-step explanation:

so first arranging these numbers in ascending order

we get

9,40,42,50,61,63,79,80,95,109

so here there are total 10 terms

thus N=10

so we know that

Mean=sum of all terms of given data/total terms

=9+40+42+50+61+63+79+80+95+109/10

=628/10

=62.8

thus the mean of given data is 62.8

now as here there are total 10 terms

and 10 being an even number

we would be using formula

ie median=(N/2+1)th term

=(10/2+1)th term

=(5+1) term

=6th term

so here 6th term is 63

so median=63

thus our median is 63

now here as no number is repeated more than once here there is no mode possible

but 109 being the highest number in the given data can be considered as modal number

but mode is not possible

thus mode of above data=phi ie null
