Question

Suppose that a radio station predicted that Candidate A would defeat Candidate B in a certain election. They conducted a poll of its listeners with a response rate of 24%. On the basis of the results, the radio station predicted that Candidate A would win with 57% of the popular vote. However, Candidate B won the election with about 62% of the popular vote. At the time of this poll, most listeners of the station belonged to the party of Candidate A. Name two biases that led to this incorrect prediction Choose the correct answer below. ○ A. Sampling bias Using an incorrect frame led to undercoverage. Response bias: The way the poll was administered showed bias B. Sampling bias: Using an incorrect frame led to undercoverage Nonresponse bias: The low response rate caused bias Nonresponse bias: The low response rate caused bias. Response bias: The way the poll was administered showed bias. OC.

Answer 1

B. Sampling bias: Using an incorrect frame led to under coverage Non response bias: The low response rate caused bias

Explanation:

The two biases that led to this incorrect prediction are as follows:

The response rate was very less and wrong predictions were made.

Sampling Bias: Using an incorrect frame that led to under coverage.

Non response Bias: The low response rate caused bias.
