AB-Testing-Gym-Membership

Evaluate Hypothesis that fitness test intimidates some prospective members of the Gym.

Description

A/B Testing

Randomly assign visitors to the following two groups:

  • Group A : Gym visitors who are asked to take a fitness test with a personal trainer.
  • Group B : Gym visitors who are asked to proceed directly to fill in the application, skips the fitness test.

Hypothesis

  • Null Hypothesis (H0) : There will no difference between the visitors in Group A that purchase membership and the visitors in Group B that purchase membership.
  • Alternate Hypothesis (H1) : There will be more visitors in Group B that will purchase membership than visitors in Group A that will purchase membership.
  • The significance threshold we will set as the benchmark to either accept or fail to reject the null hypothesis will be: 𝛼 = 0.05

Intersting Learnings:

  • How to determine if statistical significance is important or not ?
  • How to build Hypothesis ?
  • How to choose a hypothesis test for a given problem ?

Install Setup

This project requires Python 2.7 and the following Python libraries installed:

You will also need to have software installed to run and execute a Jupyter Notebook

If you do not have Python installed yet, it is highly recommended that you install the Anaconda distribution of Python, which already has the above packages and more included. Make sure that you select the Python 2.7 installer and not the Python 3.x installer.
