-18, 10, -20, -11, 9, 18 Mean Median Mode Range

Vlada [557]

Mean = -2

Median = -1

Mode = Nil

Range = 38

Step-by-step explanation:

Given data is:

-18, 10, -20, -11, 9, 18

Arranging the data in ascending order

-20, -18, -11, 9, 10, 18

Mean:

Mean is given by the formula

$Mean=\frac{Sum}{items}$

Items are: 6

$Mean = \frac{-20-18-11+9+10+18}{6}\\= \frac{-12}{2}\\= -2$

Mode:

Mode is the most frequent value in the data. So,

As there is no value repeated in the data. There is no mode

Median:

Median is the middle value of the data. As the no. of data value are even,

the average of middle 2 values is mode.

Note that the data has to be arranged in ordered to find median

Here,

$Median = \frac{-11+9}{2}\\=\frac{-2}{2}\\= -1$

Range:

Range is the difference between the largest and smallest value of the data

Here

Largest value = 18

Smallest value = -20

So,

$Range = Largest\ value-Smallest value\\= 18-(-20)\\= 18+20\\=38$

Hence,

Mean = -2

Median = -1

Mode = Nil

Range = 38
