Answer 1

$\Large \fbox \red {Question \: :}$

Find the mean, mode, median and range of data 4, 5, 3, 6, 3, 5, 3, 4, 3.

$\Large \fbox \red {Answer \: :}$

$\implies$ First we arrange the data in ascending order.

$\implies$ 3, 3, 3, 3, 4, 4, 5, 5, 6

• Mean :

Arithmetic mean = $\frac {Sum \: of \: data} {Total \: number \: of \: data}$

Arithmetic mean = $\frac {3+ 3 + 3 +3+4+ 4+ 5 + 5 +6} {9}$

Arithmetic mean = $\frac {36} {9}$

Arithmetic mean = 4

$\therefore$ Mean = 4

• Mode :

Mode is that digit which has largest frequency in data.

So, the digit which has largest frequency is digit 3.

$\therefore$ Mode = 3

• Range :

Range = Highest term - lowest term

= 6 - 3

= 3

$\therefore$ Range = 3
