The problem with relying on a point estimate of a population parameter is that:

A) it is virtually certain to be wrong.
B) it doesn't have the capacity to reflect the effects of larger sample sizes.
C) it doesn't tell us how close or far the point estimate might be from the parameter.
D) All of these choices are true.

Point Estimate

A single value that serves as the best guess or most likely value for a population parameter based on sample data.

Population Parameter

A numerical value that describes a characteristic of a population, such as mean, standard deviation, proportion, etc., usually estimated through samples.

Larger Sample Sizes

Refers to increasing the number of observations in a study to improve the reliability and validity of statistical inferences.
