WebP Value Calculator. Use this calculator to compute a two-tailed P value from any Z score, T score, F statistic, correlation coefficient (R), or chi-square value. Once you have obtained one of these statistics (from a publication or even another program) the P value helps interpret its statistical significance. WebStem-and-leaf plots, which show all data values and the shape of the distribution. Histograms, a bar plot in which each bar represents the frequency (count) or proportion (count/total count) of cases for a range of values. Box plots, which graphically depict the five-number summary of minimum, first quartile, median, third quartile, and maximum.
