A) Probability
B) Degrees of freedom
C) Goodness of fit
D) Random sampling error
E) Standard error

Question

Quizplus · Accepted Answer

The deviation between observed numbers and expected results is a type of random error that occurs in the process of randomly sampling from a population. This type of error is known as random sampling error. The other options listed do not accurately describe this type of error. Probability refers to the likelihood of a certain event occurring. Degrees of freedom and goodness of fit are statistical concepts used in hypothesis testing, but they do not describe the deviation between observed and expected results in a specific sample. Standard error refers to the standard deviation of the sampling distribution and is also not the best choice in this context.
