Question

Find the median of the following minutes taken to write a test as:15,18,9,10,10,12,8,9,16,12,13,11,8,9,14,15, the answer should be 11.5

Answer 1

Answer:

8,8,9,9,9,10,10,11,12,12,13,14,15,15,16,18

n=total n0 of minutes=16, where th stands 4 de position

median: 1/2(n)th and 1/2(n+1)th

1/2 x 16  and 1/2 x 16+1

8th position and 8+1=9th position, 8th position=11 and 9th position=12

11+12/2=23/2=11.5

Step-by-step explanation: using the formula, u follow the steps; that is, first arrange in ascending order(lowest to the highest), find the total outcome/numbers of minutes given, and substitute it in the formula.

Answer 2

Step-by-step explanation:

first arrange it into ascending or descending order.

If we arrange in ascending order, it will be as:-

8,8,9,9,9,10,1011,12,12,13,14,15,15,16,18

we see that there are 16 terms.

we will separate 7 numbers from both side and average of 8th and 9th term will be the answer

8th term = 11

9th term = 12

average = 11 + 12 /2

= 23/2 = 11.5
