Answer 1

Question ⤵️

what is the range of the data given below

31,38,27,28,36,25,35,40.

Solution ⤵️

Given ⤵️

Observations:- 31, 38, 27, 28, 36, 25, 35, 40

 

Arranging given numbers in ascending order:

= 25 , 27 , 28 , 31 , 35 , 36 , 38 , 40

Number of observations, (n) = 8 (even)

Median = ½[value of (n/2)th + (n/2 +1)th observations]

Median = ½ [value of (8/2 th + (8/2 + 1 th) observations]

Median = ½ [value of (4th + 5th) observations]

Median = (31 + 35)/2  

Median =  66/2 th  

Median = 33  

Therefore, the median of the given data is 33.

 

Answer:- The median of the data is 33.
