The lower fence is the "lower limit" and the upper fence is the "upper limit" of data, and any data lying outside these defined bounds can be considered an outlier. The fences provide a guideline by which to define an outlier, which may be defined in other ways. The fences define a "range" outside which an outlier exists; a way to picture this ...
The lower quartile corresponds with the 25th percentile and the upper quartile corresponds with the 75th percentile, so IQR = Q 3 − Q 1 [1]. The IQR is an example of a trimmed estimator , defined as the 25% trimmed range , which enhances the accuracy of dataset statistics by dropping lower contribution, outlying points. [ 5 ]
Each group has a lower limit (L k) and an upper limit (U k). When the class ( k ) contains m k data and the total number of data is N , then the relative class or group frequency is found from: Fg ( L k < X ≤ U k ) = m k / N
The income you need to fall in America's lower, middle and upper classes — find out where you rank and how these social levels are defined Douglas Warren February 3, 2024 at 7:21 AM
This means that lower-income households had incomes below $56,600, and upper class households had incomes above $169,800. You may be curious to know where you stand in the context of upper, middle ...
The points plotted as part of an ogive are the upper class limit and the corresponding cumulative absolute frequency [2] or cumulative relative frequency. The ogive for the normal distribution (on one side of the mean) resembles (one side of) an Arabesque or ogival arch, which is likely the origin of its name.

In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.
