Web5 feb. 2024 · Years ago, when I first started split-testing, I thought every test was worth running.It didn’t matter if it was changing a button color or a headline—I wanted to run that test. My enthusiastic, yet misguided, belief was that I simply needed to find aspects to optimize, set up the tool, and start the test. WebIn the digital marketing universe, the standard is now that statistically significant results value alpha at 0.05 or 5% level of significance. A 95% confidence level means that there is a 5% chance that your test results are the result of a type 1 error (false positive). Why is it important to watch out for type 1 errors? huron river days
