Answer 1

The major potential sources of error in any study include systematic error (bias) and random error (chance). Chance error occurs when the sample size is too small, while bias occurs when the sample is not selected randomly. Both errors can be minimized.

Step-by-step explanation:

The subject of this question is Statistics.

In statistics, the major potential sources of error in any study include systematic error (bias) and random error (chance). Chance error occurs when the sample size is too small, resulting in the sample not fairly representing the whole population. This can be minimized by using a larger sample. Bias occurs when the sample is not selected randomly with respect to a variable in the study, and it can be minimized by choosing a randomized sample.
