Class Interval Definition Class interval refers to the numerical width of any class in a particular distribution. Mathematically it is defined as the difference between the upper class limit and the lower class limit.Importance of Class Interval...
To find the lower class boundary (L) of a class in a frequency distribution when given the upper class boundary (U) and the midpoint (M), we can follow these steps:1. Understand the relationship between U, L, and M: - The mi
For example, if the number of students in each ascending 10-point, whole-number interval from 50 to 59, 60 to 69, etc. up to 90-99 is 2, 6, 11. 4 and 3, then the teacher might choose to assign F to the 2 in lowest range, D to the next 6 and so on, since the raw scor...

Multiply by the class frequency to get column 7. Finally, add them all up and divide by the total number. This gives the variance: σ2=446.5100=4.465 and the standard deviation σ=446.5≈2.11. The relative frequency (given in column 8) is the fraction in each class interval; that is, ...
Class width represents the size of each class in agrouped frequency distribution. It is the distance between theupper class limitand thelower class limitof a class interval: Class Width = Upper Class Limit − Lower Class Limit. For example, if a class interval is “118 – 125,...
For a frequency distribution, the class midpoint is:? the difference between consecutive lower limits.the class frequency divided by the number of observations.the number of observations in the class.the class interval divided by two and added to the lower limit. 相关知识点: 试题来源: 解析 ...
