This article holds the key to unlock the secrets of using the mean formula in Excel. Join us as we unravel its significance, unveil its calculations, and empower you to harness its potential with confidence. Let's embark on this enlightening journey together! Part 1: When should the mean be...
Alpha – This is the significance threshold. By default this is set at 0.05. So, if the p<0.05, we can reject the null hypothesis and conclude that the test is statistically significant The output options underneath are used to determine where the F-test results will be returned. ...
Additionally, if you have a large sample size, the f-test has morestatistical power. This condition can cause the test to identify an inconsequential difference as being statistically significant. That’s thedifference between practical significance and statistical significance. Conversely, small sample ...
Another factor to consider when conducting a t-test is the level of significance, or alpha, that you choose. The most common level of significance is 0.05, meaning that there is a 5% chance of obtaining a result as extreme as the one observed, assuming that the null hypothesis is true. ...
