Any experiment that involves later statistical inference requires a sample size calculation done BEFORE such an experiment starts. A/B testing is no exception. Calculating the minimum number of visitors required for an AB test prior to starting prevents us from running the test for a smaller sample size, thus having an “underpowered” test.Read More
My first experience as a speaker and attendee at the INBOUND18 conference was great. I was taken aback by all the glitz and glamour of such a large show. The lineup of keynotes and spotlight speakers was exciting with names like Beth Comstock, Shonda Rhimes, Reid Hoffman, Deepak Chopra, 2DopeQueens, and A-Rod (no J-Lo did not make a surprise appearance).Read More
I will take you back to 2007 to one of the very first CRO projects we conducted for a large online retailer. The website received a massive amount of traffic (100k per day). Since it was one of our first projects, and the team was a bit trigger happy with AB testing, our first test included 30 different designs to run against the control. The headache of implementing all of these designs was overwhelming. None the less, we launched the test after about six weeks of implementation.
Seven of our challengers beat the original design within five days. The team …Read More

There are millions of aspiring entrepreneurs with actually really good ideas. But ideas are a dime a dozen. From those ideas, only a few convert their concept into a company. And that’s just the beginning of a long struggle. As per data collected by Smallbiztrends startup failure rate is quite astonishing. Only 4% of small business startups could make it to their second year (2011 data). Investopedia also states that even though every month, over half a million new businesses spur, only 50% of those shut down within less than five years.

I have meant to write this post for a long time. There has been a lot written about one-tailed vs. two-tailed tests. However, most of the articles approach the topic from a purely statistical perspective providing many formulas but do not show how to do the calculations.
