Classify the following variable as categorical or quantitative, and discrete or continuous.
Time it takes police to respond to 9-1-1 call
Quantitative variables:
The variable that records a numerical quantity is termed as quantitative variable. In other words, these variables can be counted or measured. Age of people, heights of students, land area are some of the examples for quantitative variables.
Continuous variable:
A continuous variable takes infinitely number of values that is this variable takes infinite values between two specified numbers. This variable is measured on the continuous or interval scale.
In the given situation, the time taken by the police for responding to 9-1-1 call.
The variable 'time' is measured on numerical scale.
Hence, the variable is quantitative variable.
