Answer 2

Answer:

The median value of X is

Option d. 12

Step-by-step explanation:

The median of the set of data is the middlemost number or center value in the set.

The formula to calculate the median of the data set is

1. For an odd number of the data set

$Median = (\frac{(n+1)}{2} )^{th}$  term

2. For an even number of the data set

$Median = [(\frac{n}{2}) ^{th}term+(\frac{n}{2}+1) ^{th} ]/2$

In both formulas, n is the number of observations in the data set.

The values of X are given by 6, 7, 9, 12, 15, 19, 19

There are seven numbers in the given data set (n = 7)

Seven is an odd number so, to find the median use the formula 1

$Median = (\frac{7+1}{2} )^{th} term$

Median = 4th term

Therefore median of the given data set 6, 7, 9, 12, 15, 19, 19  is 12
