This extension calculates statistical significance for experiments.
Ever get tired of having to open Excel or a dedicated website with an A/B test significance calculator? I know I did. With this easy A/B testing statistical significance calculator you can easily check your experiments for statistical significance. – The perfect extension for AB-testing for digital marketing (AdWords, Facebook ads), conversion optimization and more. – Gives you both the conversion rates, p-values and a summary of whether or not the result is considered 'statistically significant' with a 95% confidence level. Protip: Add your own custom keyboard shortcut for this plugin by going to Settings -> Extensions, scrolling down to the bottom and clicking 'Keyboard Shortcuts'. I use Cmd-Shift-S for easy access on my Mac :-).
