Question

Determine whether the data are from discrete data or continuous data set.

CHIS :Among the subjects surveyed as part of the California Health Interview Survey (CHIS), several subjects are randomly selected and their heights are recorded.

Short answer

The heights of subjects that are surveyed form a continuous dataset.

Step-by-step solution

Given information

The heights are recorded for a sample of subjects who were surveyed for a health interview.

Discrete and continuous data

• Discrete data

A type of numerical value that cannot be measured but only counted is a form of discrete data. For example, the number of bones in the human body, shoe sizes, the number of goals in a match, etc.

• Continuous data

A type of numerical value that can be measured on a scale is a form of continuous data. For example, the amount of rain in a day, the speed of a vehicle, the time taken to deliver a service, etc.

Classification of data

As the heights of subjects can be measured and hold a decimal value, they form acontinuous data set.
