Answer 1

Answer:

Frequency of 12= 3

The range= The biggest number- the smallest number

⇒ 25- 5

= 20

Step-by-step explanation:

Answer 2

Question :

• Write the frequency of 12 in the given data :

12, 18, 25, 5, 7, 15, 5, 12, 15, 23, 21, 18, 12, 10, 20

• Also write the range of data.

Answer :

• 3

We can answer this by counting the given data :

12, 18, 25, 5, 7, 15, 5, 12, 15, 23, 21, 18, 12, 10, 20

• By this we can get the answer :

so, the value of 12 is = 3

We can also get the answer by using tally mark and by making frequency distribution table :

$\small \boxed{ \tt{ \frac{number}{12} \bigg| \: \frac{tally \: marks}{ | | | } \bigg | \frac{no. \: of \: 12}{3} }}$

• The number of tally marks for the 12 gives the no. of 12, and these numbers are called as frequency of the 12.

• And the table which gives us the no. of times and entry occurs is called as Frequency distribution table.

Range of data :

• Biggest number - smallest number

= B - S

= 25 - 5

= 20

• So the range of data is 20
