Using Quartile-Quartile Lines as Linear Models
Gordon, Sheldon P.
PRIMUS, v25 n5 p389-399 2015
This article introduces the notion of the quartile-quartile line as an alternative to the regression line and the median-median line to produce a linear model based on a set of data. It is based on using the first and third quartiles of a set of (x, y) data. Dynamic spreadsheets are used as exploratory tools to compare the different approaches and to investigate the effects of sample size on the lines that are produced to fit random samples.
