Question

when 11 observations are arranged in ascending, the 5th,6th and 7th observations are 12,13,16 respectively, find the median​

Answer 1

Answer:

Just follow this

Step-by-step explanation:

as the observations are odd Apply n+1/2 format

n=3

therefore

3+1/2

therefore answer is 2

Answer 2

The median is 13

Given : When 11 observations are arranged in ascending, the 5th,6th and 7th observations are 12,13,16 respectively.

To find : The median of the data.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the median of the data)

Number of observations = 11

As, 11 is an odd number, so the median of the data will be :

= [(n+1)/2] th term

(here, n = number of terms)

Now, the data is already arranged in ascending order, so we don't need to worry about the data arrangement.

In this case,

n = 11

So, median of the data :

= [(11+1)/2] th term

= 6th term

According to the data mentioned in the question,

6th term of the data = 13

So, median of the data = 13

Hence, the median of the data is 13
