Why Is a Point Estimate Alone Insufficient for Providing a Probabilistic

question 34

Multiple Choice

Why is a point estimate alone insufficient for providing a probabilistic estimate of a parameter?

• A) Because a point estimate only estimates the parameter, it will never provide us with its value.
• B) Although the point estimate provides a good guess for the parameter, it is a single value and, for a continuous variable, the probability the parameter equals this single value is 0.
• C) The calculation of the point estimate is too fraught with uncertainty to provide an accurate probability estimate.
• D) A point estimate is too static to accurately estimate a dynamic parameter.
