When the parameter mean is predicted as a single value, the technique employed is called
A) point estimation
B) error estimation
C) interval estimation
D) inferential validity

Question

Quizplus · Accepted Answer

Point estimation involves estimating a population parameter, such as the mean, by using a single numerical value based on a sample statistic. This involves using techniques such as the sample mean or sample proportion as the estimate of the population parameter, without providing an interval of possible values or an estimate of the error involved. Therefore, point estimation is the appropriate choice for this question.
