Question

Find the value of lambda if the mode of the following data is 20:
15,20,25,18,13,15,25,15,18,17,20,25,20,lambda,18


Please it's urgent

Answer 1

Answer:

lambda = 20

Step-by-step explanation:because mode is the observation reapeated the most number of times

if lambda is not 20 then the mode will not be 20 therefore it contradicts the question

hence lambda = 20

Answer 2

Arranging the data in ascending order

we get ,

13,15,15,15,17,18,18,18,20,20,20,25,25,25

But , here the mode is 20 (given)

therefore, value of lambda is 20 Ans ...
