representation. n. 1. the act or an instance of representing or the state of being represented. 2. anything that represents, such as a verbal or pictorial portrait. 3. anything that is represented, such as an image brought clearly to mind.
The standard deviation and range are both measures of the spread of a data set. Each number tells us in its own way how spaced out the data are, as they are both a measure of variation. The range relies on a very simple formula of subtracting the minimum data value from the maximum.
on whether the Interval Type is set to Lower Limit or Upper Limit. Standard Deviation S (Standard Deviation) Enter an estimate of the standard deviation (must be positive). The sample size and width calculations assume that the value entered here is the standard deviation estimate that is obtained from the sample.imilarly, the one-sided 100(1 â Î±)% lower confidence limit is 1 221 1 1 /, ï£¾ï£½ï£¼ï£³ï£²ï£± â â n â ns Ï Î±For two-sided intervals, the distance from the standard deviation to each of the limits is differen t. Thus, instead of specifying the distance to the limits we specify the width of the interval, W.
