The repository contains my third project that I completed towards the Udacity Data Analyst Nanodegree. The purpose of this project was to conduct an A/B test on whether or not a e-commerce website company should implement a new page design, keep their old page or run the experiment for longer and hold off from making a decision.
Since this was an A/B test, the following null and alternative hypothesis were proposed:
-
$H_{0}$ :$p_{new}$ -$p_{old} \leq 0$ -
$H_{1}$ :$p_{new}$ -$p_{old}$ > 0
In plain English, our null proposes that the views of the new page - the views of the old page would be less than or equal to 0 and our alternative hypothesis proposes that this is greater than zero. Therefore is this a one-sided t-test.
You can view the analysis by looking at the Jupyter Notebook file or by examining the html file output.
In this project, I implemented the following Python libraries:
- Pandas
- Numpy
- Random
- Matplotlib
- Statsmodels
