Question

Indicate whether the method described below of collecting data is biased or not. If it is biased, suggest one type of bias taking place and explain your answer in a brief sentence.

In the spring, a researcher wants to count the population of the stink bug, an invasive species. She goes into a residential neighborhood and asks residents how many bugs they have seen in the last week.

Answer 1

Yes, the method described below of collecting data is biased.

For most, spring means more daylight and blooming flowers. As the temperatures begin to rise, many insects come out of various overwintering situations and become more active. Because of this, you may begin to see some common pests in your house. Bugs can be active at night because the air temperature is still high, and the temperature of the ground is warm. This keeps them going for most of the night.
