प्रश्न
Calculate the median of the following sets of number:
1, 9, 10, 8, 2, 4, 4, 3, 9, 1, 5, 6, 2 and 4.
उत्तर
Arranging these numbers in ascending order,
1, 1, 2, 2, 3, 4, 4, 4, 5, 6, 8, 9, 9, 10
Here N = 14
∴ `("N"/2)^"th"` term
= `(14/2)`
= 7th term
= 4
`("N" /2 + 1)^"th"`term
= 7 + 1
= 8th term
= 4
∴ Median
= `(4 + 4)/(2)`
= `(8)/(2)`
= 4
Or
Median = 4.
