Answer 2

The correct options are:

• Four families said that they went out for dinner twice the previous week.

• one family said that they ate out 5 times the previous week.

• The median best represents the data set.

Explanation:

Based on the data we make a frequency table as follows:

Number of times Frequency

family went for dinner

0 2

1 3

2 4

3 1

4 2

5 1

6 1

• The range of the number line should be from 0 to 6 to represent the frequency.

• Also, as the frequency corresponding to 2 is 4.

Hence, 4 families said that they went out for dinner twice the previous week.

• As the frequency corresponding to 5 is 1.

Hence, one family said that they ate out 5 times the previous week.

• The data is not symmetrical since there is no such point about which the data is symmetric.

• Also, we know that the median is the central tendency of the data and best represent the data.
