WebClass interval is a term that is used to denote the numerical width of a class in a frequency distribution. In a grouped frequency distribution, data is arranged in the form of a class. The difference between the upper-class limit and the lower limit gives the class interval. In statistics, there are two types of class intervals, namely ... WebFeb 8, 2024 · The APA 6 style manual states (p.117): “ When reporting confidence intervals, use the format 95% CI [LL, UL] where LL is the lower limit of the confidence interval and UL is the upper limit.”. For example, one might report a 95% CI [5.62, 8.31]. Confidence intervals can also be reported in a table.
