Question

he median of 11 observations is 10. The number of possible observations in the data which are less than 10 is ?

Answer 1

Answer:

5 observations

Step-by-step explanation:

Since the median is 10, the middle most term of the observations, when they are arranged in ascending order, is 10.

Middle term = ( 11 + 1 ) / 2 = 12 / 2 = 6th term

Hence, when arranged in ascending order, the 6th term is 10.

Thus, the first 5 terms can be less than 10.

Therefore, ANS = 5 observations

Answer 2

Answer:

5

Step-by-step explanation:

number of observations =11 (odd)

therefore, median= value of (n+1)/2

11+1 /2 = 6th observation.

Therefore there are 5 observations less than 10
