Question

Tenth20, 13, 13, 6, 3, 12, 7, 20, 20Range:x✓x f(x) VX X(x) x] 3 2TTMean:Median:

Answer 1

Range = Highest value - Lowest value

= 20 - 3

= 17

Mean =

`\frac{Sum\text{ of all the items}}{total\text{ number of items}}\text{ = }\frac{20\text{ + 13 + 13 + 6 + 3 +12 + 7 + 20 + 20}}{9}=\text{ }(114)/(9)\text{ = }(38)/(3)`

Median = Middle value when the items are arranged in either increasing or decreasing order

Arranging the items In increasing order we have:

3, 6, 7, 12, 13, 13, 20, 20, 20.

Hence the median is the 5th item = 13

Mode = The most occuring item

The most occuring item or number is 20 (occuring three times)
