Question

Which of the following data collection activities can lead to sampling bias?

A.Collecting data on groups of people disproportionately.
B.Collecting data that has outliers.
C.Collecting data that has too many features.

Answer 1

Collecting data on groups of people disproportionately can lead to sampling bias. So, the correct option is A. Collecting data on groups of people disproportionately.

Step-by-step explanation:

In statistics, a sampling bias is created when a sample is collected from a population and some members of the population are not as likely to be chosen as others.

This can lead to inaccurate conclusions about the population being studied. Collecting data on groups of people disproportionately can result in sampling bias.

For example, if a survey of all students is conducted only during noon lunchtime hours, it is biased because students who do not have a noon lunchtime would not be included.

So, the correct option is A. Collecting data on groups of people disproportionately.
