Question

find the median of the following date set:

74,52,28,31,49,54,32,66,59,86​

Answer 1

arrange following numbers in small number to big number order

28, 31 ,32 , 49 ,52 , 54 , 59 ,66 ,74 , 86

median is 52 and 54

add the both 52 + 54 / 2

106 / 2 = 53

Answer 2

Step-by-step explanation:

Question:-

Find the median of the data:-

74,52,28,31,49,54,32,66,59,86

Answer:-

Given : 74,52,28,31,49,54,32,66,59,86

To find : The median of above data

Process:-

Data arranged in ascending order :-

28,31,32,49,52,54,59,66,74,86

Total No. of whole data = 10 numbers (even)

∴ We know that in median for even frequency :-

➔ Median = (n/2) term + (n/2+1) term /2

⇒ Median = (10/2) term + (10/2+1) term /2

⇒ Median = 5th term + (11/2) term /2

⇒ Median = 5th term + 5.5 (round off to 6) /2

⇒ Median = 5th term + 6th term/2

⇒ Median = 52+54/2

⇒ Median = 106/2

⇒ Median = 53 (Ans)

∴ The median of above data is 53.
