WebSep 2, 2024 · Type 1 errors are commonly known as false positives. A type 1 error occurs when a null hypothesis is rejected during hypothesis testing, even though it is accurate. In this type of error, we conclude that our results are significantly correct when they’re not. WebMar 26, 2016 · The outcome of a statistical test is a decision to either accept or reject H 0 (the Null Hypothesis) in favor of H Alt (the Alternate Hypothesis). Because H 0 pertains to the population, it's either true or false for the population you're sampling from. You may never know what that truth is, but an objective truth is out there nonetheless.
