Midinterval is a term used to denote the midpoint of a closed interval. For an interval [a, b], its midinterval is (a + b)/2. This point lies exactly halfway between the endpoints and is sometimes called the interval midpoint or class mark.
In mathematics and numerical methods, the midinterval serves as a central representative value for the interval.
In statistics, when data are grouped into classes or bins, the midinterval (or class mark) of a
In data collection and measurement, if the exact time or value of an event is unknown but
