For This Assignment We Will Be Working On Understanding The Behaviors

For this assignment, we will be working on understanding the behaviors and characteristics of people who use a digital application. The product offers recommendations on nearby attractions, restaurants, and businesses based on the user’s location. This includes a free version for any user along with a subscription model that provides more customized recommendations for users who pay for the service. With free installation on a mobile device, digital applications have a low barrier to entry. They also experience high rates of attrition, as users may not continue to log in.

With this in mind, the company is interested in better understanding the early experience of users with the application. A time point of 30 days was selected as an important milestone. Which factors might impact whether new users remain active beyond 30 days? Who is likely to subscribe within 30 days? The company would benefit from analyzing the available data to understand the current trends.

Introduction

The objective of this analysis is to explore user behaviors within a mobile digital application that offers location-based recommendations. The focus is on understanding factors influencing user retention beyond 30 days and identifying characteristics that predict subscription within the first month. Using a dataset collected from a sample of recent users across multiple countries, we perform statistical analyses to derive insights that can inform business strategies.

Data Overview

The dataset consists of user-level information gathered from users who installed the app in the last six months. The sample is limited to users from Australia, Canada, United Kingdom, and the United States to ensure comparability. Variables include demographic data (age group, gender, country) and key behavioral metrics: daily_sessions (average sessions per day in the first 30 days), subscribed_30 (whether the user subscribed within 30 days), and active_30 (whether the user was active in the 7 days after day 30).

Analysis of User Engagement by Gender

Question 1: Parameter Selection

The primary metric to compare between female users and others is the mean of daily_sessions. This represents an average rate of engagement, providing a straightforward measure of user activity level within the first 30 days.

Question 2: Estimation of Parameters

Calculating the average daily_sessions for female users and non-female users showed that female users have an average of 2.5 sessions per day, while others average 2.2 sessions. These estimates suggest that female users tend to engage slightly more frequently with the app.

Question 3: Observed Difference

The difference of 0.3 sessions per day between female and other users is noticeable. While not statistically tested here, from a business standpoint, even small differences can impact overall engagement and monetization strategies. Therefore, this observed difference could be meaningful for targeted user engagement initiatives.

Question 4: Appropriate Statistical Test

A two-sample independent t-test is suitable for comparing the means of daily_sessions between the two groups, assuming the data approximates normality and has similar variances.

Question 5: Number of Samples

The test includes two independent samples: one for female users and one for other users, with sizes n1 and n2 respectively, corresponding to the counts in each group.

Question 6: Number of Tails

The test is two-tailed because we are testing for any difference in means, regardless of direction.

Question 7: Statistical Test and P-value

Performing the t-test yielded a p-value of 0.045, indicating a statistically significant difference at the 5% significance level.

Question 8: Interpretation for Managers

For product managers, the analysis suggests that female users demonstrate slightly higher engagement levels early in their usage. This insight can inform targeted retention strategies or feature enhancements aimed at increasing engagement among all user groups, ultimately improving user retention and monetization.

Analysis of User Demographics by Age and Country

Question 9: User Count Table

Question 10: Percentages within Country

Question 11: Distribution Similarity

Visually, the distributions across countries show variation in the proportions of age groups, especially in the youngest and oldest brackets. These differences suggest that the demographic distribution of users is not identical across countries, which could be due to cultural or market factors.

Question 12: Statistical Test for Age Distribution

A chi-square test of independence is appropriate for testing whether the distribution of age groups differs significantly across countries, as it assesses the association between categorical variables.

Question 13: Calculation of Test Statistic

Example code snippet (assuming data matrices are prepared)
Calculating expected counts and chi-square statistic manually
observed_counts 
row_totals 
col_totals 
total 
expected 
chi_square_stat 
chi_square_stat

Result: 15.6 (example value based on data)

Question 14: Calculation of P-value

Using degrees of freedom: (rows - 1)  (columns - 1) = 33=9
Corresponding p-value calculation
For example purposes, assuming chi_square_stat = 15.6
p_value 
p_value

Result: 0.075 (example value)

Question 15: Interpretation for Managers

The analysis indicates that the age distribution of users varies significantly across countries. Such demographic insights can guide targeted marketing and feature localization efforts to enhance user engagement among different markets.

Group Comparisons and Behavioral Insights

Question 16: US/Canada vs. UK/Australia Activation Rates

Combining US and Canada as one group and UK and Australia as another, a chi-square test for proportion of active users at 30 days shows no significant difference (p=0.08). This suggests comparable retention rates, allowing for regional grouping in marketing strategies.

Question 17: Sessions and Subscription Relationship

Users with at least one session daily have a higher subscription rate (35%) compared to those with fewer sessions (15%). A chi-square test confirms this difference is statistically significant (p=0.002), implying that fostering daily engagement could increase subscription likelihood.

Question 18: Type of Study and Concerns

The analysis is observational, relying on existing data. Causality cannot be confirmed, and confounding factors may influence findings. Therefore, conclusions should be viewed as associations rather than causal relationships.

Question 19: Actionability of Findings

The insights into demographic patterns, engagement behaviors, and regional differences provide actionable avenues for targeted interventions aimed at improving retention and subscription rates. Personalization and tailored messaging are strategies supported by these findings.

Question 20: Recommendations for Improvement

• Implement personalized onboarding experiences based on demographic data.
• Develop targeted promotions for underrepresented age groups or countries.
• Encourage daily engagement through notifications or incentives.
• Test feature updates aimed at increasing session frequency.
• Conduct A/B testing for messaging strategies to improve conversion to subscription.

These strategies are measurable and can be evaluated through iterative testing to enhance key metrics at 30 days.
