Definitions:

Confidence Interval

A swath of numerical values, from statistics of a sample, aimed at covering the unascertained value of a population parameter.

Margin of Error

The half-width of a confidence interval, representing the maximum expected difference between the true population parameter and a sample estimate of that parameter.

Population Standard Deviation

A measure of the dispersion or spread of a set of data values in a population, indicating how much individuals within this population vary from the population mean.

Interval Estimate

An estimate of a population parameter that provides a range of values believed to contain the parameter with a certain degree of confidence.
