CLASS MARK Meaning and
Definition
-
The term "class mark" is commonly used in the field of statistics and refers to a concept within the realm of data analysis and categorical data representation. Specifically, it is used when working with grouped frequency distributions, which involve organizing data into intervals or classes and recording the frequency of observations falling within each interval.
The class mark, also known as the midpoint or average of a class, represents the value located at the center of an interval. It is calculated by finding the average of the lower and upper boundaries of the class. In essence, the class mark acts as a representative value for each class interval.
This statistical measure is useful in summarizing and analyzing data, as it provides an indication of the central tendency of a class. By identifying the class marks, it becomes possible to interpret the data accurately and make meaningful inferences. Additionally, the class marks allow for the construction of histograms, which provide a visual representation of the distribution of data.
For example, suppose a frequency distribution groups ages in intervals of 10 years, starting from 20 to 29 years, then 30 to 39 years, and so on. The class mark for the first interval would be calculated as (20 + 29) / 2 = 24.5, representing the central age of that class.

Etymology of CLASS MARK
The term "class mark" has its etymology in two separate words: "class" and "mark".
1. "Class" comes from the Latin word "classis", which originally meant "a division of people" or "a group of people with a common status or occupation". Over time, it evolved to refer to a group or category based on various criteria, such as social, economic, or educational status. The word "class" entered the English language during the late 16th century, retaining its original meaning.
2. "Mark" originated from the Old English word "mearc" or "mearca", which generally meant a boundary or frontier. Gradually, it also began to signify something used to distinguish or identify, such as a sign, symbol, or impression. In the context of education, a "mark" can refer to a grade or score that indicates a student's performance or achievement.
