CLASS INTERVAL Meaning and
Definition
-
The term "class interval" refers to a segment or range into which a set of data values is divided or grouped when creating a frequency distribution. It represents the difference between the upper and lower boundaries of each group. Class intervals are used in statistics to organize and summarize data for easy analysis.
In a class interval, the lower limit signifies the smallest possible value within the range, while the upper limit represents the largest value. The width of the class interval is determined by subtracting the lower limit of a class from the upper limit. For instance, if a class interval ranges from 10 to 20, the width would be 20 - 10 = 10.
Class intervals are typically selected based on the number of data points and the desired level of detail. They should be mutually exclusive and cover the entire range of the data. The number of class intervals affects the visibility of patterns in the data, with too few intervals resulting in loss of information, and too many intervals leading to an overwhelming display.
Once data is classified into class intervals, a frequency distribution can be created by counting the number of data points that fall into each interval. This allows for a compact summary of the data, making it easier to interpret and analyze. Class intervals are an essential tool for organizing and presenting data in a meaningful way for statistical analysis.

Etymology of CLASS INTERVAL
The word "class interval" is a term commonly used in statistics and mathematics. The etymology of this term can be broken down as follows:
1. Class: The word "class" originated from the Latin word "classis", which referred to a division or group. In English, it came to be used to describe a group of people or objects with similar characteristics or qualities.
2. Interval: The word "interval" comes from the Latin word "intervallum", which was a combination of "inter" meaning "between" and "vallum" meaning "rampart" or "barrier". In English, it refers to a space or period of time between two events or points.
So, when combined, the term "class interval" refers to the specific ranges or divisions used to group data in statistics or mathematics, where each interval represents a category or class of values within a data set.
