WebThe Brown-Forsythe test is conceptually simple. Each value in the data table is transformed by subtracting from it the median of that column, and then taking the absolute value of that difference. One-way ANOVA is run on these values, and the P value from that ANOVA is reported as the result of the Brown-Forsythe test. How does it work. WebUse 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. Learn more about how to find P value statistics in the ...

WebNov 7, 2024 · The test statistic for a goodness-of-fit test is: ∑ k (O − E)2 E. where: O = observed values (data) E = expected values (from theory) k = the number of different data cells or categories. The observed values are the data values and the expected values are the values you would expect to get if the null hypothesis were true.
