The first house in the neighborhood around the park was selected randomly and then every 8th house in the neighborhood around the park was interviewed.

鈥淣umber of times per week鈥� is what type of data?

a. qualitative

b. quantitative discrete

c. quantitative continuous

Short Answer

Expert verified

Number of times per week is a quantitative discrete variable.

Step by step solution

01

To determine

The type of data.

02

Explanation

Quantitative variables are those that can be stated numerically. We consider this variable to be quantitative because the number of times a resident visits the local park is given numerically. Discrete variables are those that can only be stated in whole numbers rather than decimals.

Because a resident's visits to the local park can only be indicated in whole numbers, there can only be 2 or 4 visits, but no 2.5 visits. It isn't practical to do so. As a result, the number of visits a resident makes to the neighbourhood park is a quantitative discrete variable.
