We are requesting that Excel find the value of cell B10 (the effect size) that produces a value of .8 for cell B13 (the power). Here the first entry must point to a cell that contains a formula. The second entry must be a value and the third entry must point to a cell that cont...
Two-tailed one-sample t test example:A farmer calculated last year the average of the apples' weight in his apple orchard μ0 equals 90 grams, based on the entire population.The current year he checked a small sample of apples and the sample average x̄ equals 82 kgHas the average of...
The formula to calculate the t-statistic for a one-sample T-test is shown below. Where: x̄– The sample mean μ– The hypothesized mean; in this case, the population mean sx̄– The SEM So, to work this out in Excel, click on an empty cell and enter the following… ...
Are one-tailed or two-tailed tests more common? One-tailed tests are more common when showing statistical power in one direction. Two-tailed tests are more common when showing statistical power between two groups. How do you know if it is one or two-tailed? A test is one-tailed when it...

Right-tailed, for ANOVA test you can use only the right tail.Why? Hypotheses H0: μ1= ... = μk H1: not(μ1= ... = μk) ANOVA formula F distribution Assumptions Independent samples Normal distribution of the analyzed population
What this critical value means in a one tailed t test, is that we would expect most values to fall under 1.711. If our calculated t-value (from Step 4) falls within this range, the null hypothesis is likely true. Step 5: Compare Step 4 to Step 5. The value from Step 4 does no...
runs = 10. Sincen1 ≤ 20, we need to use the runs table inRuns Test Table. Consulting the runs table we see that runs in the interval [8, 19] are acceptable. Sincer= number of runs = 10 is in this interval, we cannot reject the null hypothesis at the 5% level (2-tailed test)...
