Question

Solve this problem of stat.

Answer 1

Numbers are 92 , 35 , 67 , 85 , 72 , 81 , 56 , 51 , 42 , 69

Arranging the numbers in ascending order

35 , 42 , 51 , 56 , 67 , 69 , 72 , 81 , 85 , 92

n = 10(even)

\(∴ median=\frac{\frac{n}{2}th \;value+\left ( \frac{n}{2} +1\right )th\;value}{2}\)

\(=\frac{\frac{10}{2}th \;value+\left ( \frac{10}{2} +1\right )th\;value}{2}\)

\(=\frac{5th \;value+6th\;value}{2}\)

\(=\frac{67+69}{2}\)

\(=\frac{136}{2}\) = 68

hence median in is 68
