Which term describes a range of values used to estimate a population parameter and is not necessarily tied to a specified confidence level?

Which term describes a range of values used to estimate a population parameter and is not necessarily tied to a specified confidence level?

• A. Point Estimate
• B. Confidence Interval
• C. Interval Estimate
• D. Margin of Error

Answer: (C)

An interval estimate is a range of values used to estimate a population parameter. It captures the idea of estimating with a span rather than a single point, and it doesn’t have to come with a stated confidence level. You can derive different kinds of interval estimates from various methods, including Bayesian intervals, that don’t rely on a fixed confidence level. A point estimate is only a single value, not a range. A confidence interval is a specific type of interval estimate that explicitly includes a confidence level, so it’s tied to that stated level. The margin of error is the amount added to and subtracted from the point estimate to form the interval, a component of the interval rather than the range label itself.
