Question

Find the median of 45,50,60, 70, 80, 90, 75.​

Answer 1

Step-by-step explanation:

the numbers are in ascending order

no of observations are 7,

so median observation is 7+1/2=4th term

70 is the 4th term so

Median=70

Answer 2

Given: Observations: 45, 50, 60, 70, 80, 90 and 75.​

To find: The median.

Answer:

Let's first arrange them in the ascending order.

45, 50, 60, 70, 75, 80 and 90.

Formula to find the median is:

• $\sf \dfrac{n\ +\ 1}{2}$, where n is the number of observations.

NOTE: The above formula is only to be used then n is an odd number. In this case, n is odd (7).

n = 7

Median = (7 + 1)/2 = 8/2 = 4th term.

4th term ⇒ 70

Hence, the median is 70.
