TeachHist: A Collection of Amended Histograms Designed for Teaching Statistics
Description
Statistics students often have problems understanding the relation between a random variable's true scale and its z-values. To allow instructors to better visualize histograms for these students, the package provides histograms with two horizontal axis containing z-values and the true scale of the variable. The function TeachHistDens() provides a density histogram with two axis. TeachHistCounts() and TeachHistRelFreq() are variations for count and relative frequency histograms, respectively. TeachConfInterv() and TeachHypTest() help instructors to visualize confidence levels and the results of hypothesis tests.
Functions
-
TeachHistDens provides a density histogram with two axis. One axis for the data and one for the z-value.
TeachHistCounts is a variation of TeachHistDens() for count histograms.
TeachHistRelFreq is a variation of TeachHistDens() for relative frequency histograms.
TeachHistConfInterv helps to visualize confidence levels
TeachHistHypTest helps to visualize the results of hypothesis tests.
