The F Distribution Table is used to find the correct critical value of F, which determines what results are significant for a set of data. It is used for ANOVAs, where the result is an F-ratio, and in calculating the significance of a regression line (Gravetter and Wallnau, 2013). The critical F is reported in the following equations: repeated-measures ANOVA, one-way ANOVA, and factorial ANOVA. The dataset has a column for the degrees of freedom denominator (df) and 4 additional columns to give the F-value, given a degrees of freedom numerator as 1, 2, 3, or 4. The critical F is reported at .05 and 0.01 significance (α value).
Observational Stats: This function accepts a table of numbers separated by commas and calculates observational statistics for any of the columns. This includes count, min, max, sum, sum of squares (Σx²), square of the sum (Σx)², mean, median, mode, range, mid point, rand, sort up, sort down, rand, population variance, population standard deviation, the sample/experimental variance, sample/experimental standard deviation.
Frequency Distribution: This function lets you enter a string of numbers separated by commas, a low and high range and a number of bins. It then computes how many of the observations are in each of the bins between the high and low values designated.
Wilcoxon Signed Rank Test: This provides the Wilcoxon statistics and critical value for two groups of numeric observations based on an alpha value and whether it's a one or two tailed test.
