What do we mean by "Number of pets"  and Frequency?

Number of pets - the number of pets that a person has.

Frequency - ?

What do we mean by "Number of pets"  and Frequency?

Number of pets - the number of pets that a person has.

Frequency - the number of people having a certain number of pets

Frequency = 13 + 8 + 4 + 2 + 0 + 0 + 2 + 0 + 0 + 1 =

Frequency = 13 + 8 + 4 + 2 + 0 + 0 + 2 + 0 + 0 + 1 = 30

Frequency = 13 + 8 + 4 + 2 + 0 + 0 + 2 + 0 + 0 + 1 = 30

Number of pets = 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 =

Frequency = 13 + 8 + 4 + 2 + 0 + 0 + 2 + 0 + 0 + 1 = 30

Number of pets = 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
