One thing to note, a high p-value does not prove that your groups are equal or that there is no effect. High p-values indicate that your evidence is not strong enough to suggest an effect exists in the population. An effect might exist but it’s possible that the effect size is too small, the sample size is too small, or there … See more I’ve written about hypothesis testing and interpreting p-values in many other blog posts. I’ll summarize them for this blog post, but please read the related posts for more details.

To put it in simpler words, it is a calculated number from a statistical test that shows how likely you are to have found a set of observations if the null hypothesis ...
WebFeb 16, 2024 · High power in a study indicates a large chance of a test detecting a true effect. Low power means that your test only has a small chance of detecting a true effect or that the results are likely to be distorted by r andom and systematic error. Power is mainly influenced by sample size, effect size, and significance level. WebJun 22, 2024 · Interpreting the Intercept in Simple Linear Regression. A simple linear regression model takes the following form: ŷ = β0 + β1(x) where: ŷ: The predicted value for the response variable. β0: The mean value of the response variable when x = 0. β1: The average change in the response variable for a one unit increase in x.
