The formula to calculate the degrees of freedom in Equal Variance T-Tests is n1+n2-2. The Formula for the Unequal Variance T-Test This test is used when there is a difference in both the sample size and the variance of the two groups. To calculate the t-value, you must apply the fo...
This can be demonstrated with the accompanying spss syntax (limit at significant test result.sps). These sort of calculations are applied by various online tools offering to calculate sample size. This approach ignores the concept of random sampling error, thus ignoring the essence of inferential ...
Ben Eggleston's Grade Calculatorisn't anything flashy, but allows you to punch in up to 20 assignments, the grade you received on them, and what percentage of weight they carry in your final grade. At the bottom, you can choose to calculate either what your average grade on remaining assi...

Calculating the sample size required for an AB test prior to starting prevents us from running the test for a smaller sample size, thus having an “underpowered” test.
3. Calculate the Test Average Divide the result from Step 1 by the result from Step 2 to find your test average. Finishing the example, you would calculate: 253300=0.8433 4. Convert the Average to a Percentage Multiply the result from Step 3 by 100 to convert it to a percentage. To co...
