The F-Test by Hand Calculator Where possible, one-way analysis of variance summaries should be obtained using a statistical computer package. Hand-calculation is a tedious and error-prone process, especially with large data sets. This section gives formulae for calculating the F-test statistic and introduces tables of the F-distribution for

Finding P-Values using the t-distribution Here is an example showing the three methods that you can use to find the P-Value when using the t-distribution. Example: Find the P-Value for a left-tailed test with n=27 and test statistic t = -1.500 Remember that the P-Value is the probability of getting a …

p-value of 0.002 favoring group A arises very infrequently when the only di erences between groups A and C are due to chance. More precisely, chance alone would produce such a result only twice in every thousand studies. Consequently, we conclude that the advantage of A over B is

Math 124: Using the t-table to find P-values Dr Ben Bolstad bolstad math124@bmbolstad.com May 13, 2005 There are fewer P-values in a t-table then in the normal distribution table we have used earlier. The method we use is to put bounds on the P-value (ie we want …

difference between a P-value of 0.051 and 0.049. In some situations it may be necessary to proceed with some course of action based on our belief in whether the null or alternative hypothesis is true. More often, it seems better to report the P-value as a measure of evidence. A fixed level α test can be calculated without first calculating a P ...
