$\begin{array}{cc} No & 0 & 1 & 2 & 3 & 4 & 5 \\ Frequency & 1 & 4 & 3 & 8 & 2 & 5 \end{array}$ .

From the table above, find the median and range of the data respectively.

(8,5)

(3, 5)

(5 , 8)

(5 , 3)

Answer Details

Median =

\frac{\sum f x}{\sum f}

\begin{array}{cc} N o & 0 & 1 & 2 & 3 & 4 & 5 \\ F & 1 & 4 & 3 & 8 & 2 & 5 \\ f x & 0 & 4 & 6 & 24 & 8 & 25 \end{array}

\sum f x

= 0 + 4 + 6 + 24 + 8 + 25 = 67

\sum f

= 23
Median =

\frac{\sum f x}{\sum f}

=

\frac{67}{23}

= 2.913
=

\approx

3
Range = 5 - 0 = 5
(3, 5)
