For the given data, find the median
उत्तर
Given data is 31, 37, 35, 38, 42, 23, 17, 18, 35, 25, 35, 29.
Rearranging the given data in ascending order,
17, 18, 23, 25, 29, 31, 35, 35, 35, 37, 38, 42
Here, n = 12 .....(Even)
Median = `("Value of" (n/2)"th observation" + "Value of" (n/2 + 1)"th observation")/2`
= `("Value of" 6"th observation" + "Value of" 7"th observation")/2`
= `(31 + 35)/2`
= `66/2`
= 33
