Key Concepts

Confidence Interval

A confidence interval is a range of values, derived from sample data, that is likely to contain the true value of an unknown population parameter. A 95% confidence interval implies that if we were to take many random samples and build a confidence interval from each sample, we expect about 95% of the intervals to contain the true parameter.

Point Estimate

A point estimate is a single value calculated from sample data that serves as a best guess or approximation of an unknown population parameter. It is the central value around which confidence intervals are constructed.

Standard Error

The standard error measures the variability or dispersion of the sampling distribution of a point estimate. It quantifies how much the point estimate would vary from sample to sample due to random sampling error, and it is a critical component in constructing confidence intervals.

Critical Value

The critical value is a multiplier used when constructing confidence intervals, typically obtained from a statistical distribution such as the normal or t-distribution. For a 95% confidence interval, the critical value corresponds to the point that leaves 2.5% in each tail of the distribution, ensuring the desired level of confidence.
