Answer:
Sampling error is the answer.
Explanation:
A researcher selects a random sample of 500 college students from Kentucky.
It is found that 23% of students in the sample are science majors but the actual percentage of Kentucky college students that are science majors is 26%.
This depicts sampling error in collecting data.
Sampling error is the reason for the difference between an estimate and the actual value of the population parameter. This error is caused by observing a sample instead of the whole population.
