Definitions:

Confidence Interval

A range of values calculated from a set of data so that it is very likely, to a specified probability, that the true parameter of the population is within this range.

Standard Deviation

A statistic that measures the dispersion or variability of a set of data points from their mean.

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter, with a certain degree of confidence.

Millilitres

A metric unit of volume equal to one thousandth of a liter, commonly used in liquid measurement.
