From May 30th, 2014 to April 2nd, 2020, 50% user give 5-star rating, 50% user give 2-star rating. for Statistical Test for Google Analytics chrome extension.
The extension only says that "data is loading". Seems not to work. Sorry for the rating but chrom web store wants us to rate first before we write the review.
I am used to using "statistical significance" in our conversion rate optimisation, but to have it easily available directly in Google Analytics for any data is just awesome.
