Question

the observation of an underground data in their ascending order are 12,15,X,19,28. if the median of the data is 18 find the value of x​

Answer 1

The value of x = 18

Explanation:

Given the data set

`12,15,x,19,28`

• Given that the median of the data is 18.

• We know that the median is the middle number in a data set when the data points are in ascending order.

As the given data is already in ascending order.

• Please observe that the data set has an odd number of data points, meaning that the middle number is the median of the data is 18.

As 'x' is the middle number, thus it represents the median value.

Therefore, the value of x = 18
