Note 3: While using the Data Analysis Toolpak, if one does not know which t-values (of one-tail or two-tail test) are to be compared, always compare the t-statistic with the t-critical two-tail value. Example #3–Two-sample Unequal Variance T-test Using One-tail Distribution A resea...
Step 3:Insert the numbers from Step 1 and Step 2 into the test statistic formula: Solving the formula, we get: Z = 8.99 We need to find out if the z-score falls into the “rejection region.” Step 4:Find the z-score associated withα/2.I’ll use the following table of known val...

For my thesis I need to calculate p-values with Fisher test for answers to a questionnaire that i summed up in a table and I’d like to be able to do it using Excel. So i downloaded your RealStatisticPack 🙂 What does the function “FISHERTEST(matrix)” return ? Is it the p-val...
The test statistic is and the confidence interval is wheretcrit= T.INV.2T(α, df). Example For Example 1 ofTukey HSD, the LSD analysis is as shown in Figure 1. Figure 1 – LSD Test The formulas used are the same as those used in Figure 3 ofTukey HSDwith the exception that...

The F-test value that is returned by theLINEST functiondiffers from the F-test value that is returned by the FTEST function. LINEST returns the F statistic, whereas FTEST returns the probability. Example Copy the example data in the following table, and paste it in cell A1 of a new Exc...
I just want to now why the large value must be put on the Numerator while computing the F test statistic. Is "f" the value that you calculate based on the d.f., sample variance, and hypothesized variance? If that's true, does it mean the p-value for when "f" is less than or ...
The MK Test uses the following test statistic: wherese= the square root ofvar. If there is no monotonic trend (the null hypothesis), then for a time series with more than 10 elements,z∼N(0, 1), i.e. z has a standard normal distribution. ...
