The data relates to several user actions or interests recorded on two variants of landing pages for an online news portal. The objective is to analyse these interests by performing statistical analyses to determine if one variant is more effective based on chosen metrics (A/B testing).

Background

An online news portal aims to expand its business by acquiring new subscribers. Every visitor to the website takes certain actions based on their interest. The company plans to analyze these interests and wants to determine whether a new feature will be effective or not. 100 users are divided equally into two groups. The old landing page is served to the first group (control group) and the new landing page is served to the second group (treatment group). Various data about the customers in both groups are collected in 'abtest.csv'.

Objective:

• Explore the dataset and extract insights using Exploratory Data Analysis.
• Do the users spend more time on the new landing page than the old landing page?
• Is the conversion rate (the proportion of users who visit the landing page and get converted) for the new page greater than the conversion rate for the old page?
• Does the converted status depend on the preferred language?
• Is the mean time spent on the new page same for the different language users?

• user_id - This represents the user ID of the person visiting the website.
