I have just finished up a sample analysis on an AB test dummy dataset, and would love feedback.<\/p>\n

The dataset is from Udacity’s AB Testing course. It tracks data on two landing page variations, treatment and control, with mean conversion rate as the defining metric.<\/p>\n

In my analysis, I used an alpha of 0.05, a power of 0.8, and a practical significance level of 2%, meaning the conversion rate must see at least a 2% lift to justify the costs of implementation. The statistical methods I used were as follows:<\/p>\n

    \n
  1. Two-proportions z-test<\/li>\n
  2. Confidence interval<\/li>\n
  3. Sign test<\/li>\n
  4. Permutation test<\/li>\n<\/ol>\n

    See the results here<\/a>. Thanks for any thoughts on inference and clarity.<\/p>\n<\/p><\/div>\n
