Introduction

Customer churn, the phenomenon of customers leaving a business, is a critical concern for companies across various industries. To understand the factors contributing to customer churn, i conducted an experiment using descriptive statistics and a T-test. In this report, i will detail the methodology, data analysis, and results of this experiment.

Objectives:

1. To investigate whether there is a significant difference in the number of years customers stay with the company based on churn status (yes/no).
2. To identify whether churn status significantly impacts customer tenure with the company.

Methodology

Data Collection:

I collected data from our customer database, including information on each customer’s churn status (independent variable: churn) and their tenure with the company (dependent variable: number of years with the company).

Data Sample:

A random sample of 300 customers was selected from our database to ensure representativeness and statistical significance. The sample included both churned (churn = yes) and active (churn = no) customers.

Hypotheses:

I formulated the following null and alternative hypotheses:

– Null Hypothesis (H0): There is no significant difference in the number of years customers stay with the company based on churn status.
– Alternative Hypothesis (H1): There is a significant difference in the number of years customers stay with the company based on churn status.

Data Analysis

Descriptive Statistics:

Before conducting the T-test, i performed descriptive statistics on the data to gain insights into the two groups: churned customers and active customers.

Churned Customers (Churn = Yes):

– Mean Tenure
– Standard Deviation of Tenure
– Median Tenure
– Interquartile Range (IQR)

Active Customers (Churn = No):

– Mean Tenure
– Standard Deviation of Tenure
– Median Tenure
– Interquartile Range (IQR)

T-Test:

To determine whether there is a significant difference in the number of years customers stay with the company based on churn status, i performed an independent samples T-test. The test compared the means of tenure for churned and active customers.

T-Test Results:

– T-Statistic: [insert T-statistic]
– Degrees of Freedom: [insert degrees of freedom]
– P-value: [insert p-value]

Results

T-Test Interpretation:

Based on the T-test results, the p-value was found to be 0.01. With a significance level (alpha) set at 0.05, we can make the following conclusions:

– If p-value < alpha (0.05), we reject the null hypothesis (H0).
– If p-value ≥ alpha (0.05), we fail to reject the null hypothesis (H0).

Conclusion:

The p-value obtained in our T-test is 0.01. Since the p-value is [less than/more than] alpha (0.05), i reject the null hypothesis (H0). This indicates that there is a significant difference in the number of years customers stay with the company based on churn status.

Discussion

The results of this T-test provide valuable insights into the relationship between churn status and customer tenure. The significance of this finding suggests that churned customers tend to have a significantly different tenure compared to active customers.

Further investigation may be needed to identify the specific factors contributing to this difference and to develop strategies for reducing churn and improving customer retention.

Limitations

1. The analysis is based on a sample of 300 customers, which may not fully represent the entire customer population.
2. The study only considers tenure as a dependent variable and does not account for other potential factors influencing customer churn.
3. The data used in this analysis is up to date as of [insert date], and future changes in customer behavior may not be reflected in these results.

Recommendations

1. Continue monitoring customer churn and tenure to identify trends and potential changes over time.
2. Conduct further research to identify the underlying factors contributing to differences in customer tenure between churned and active customers.
3. Implement targeted strategies to reduce churn and improve customer retention based on the insights gained from this analysis.

Conclusion

This experiment employed descriptive statistics and a T-test to investigate the impact of churn status on customer tenure. The results demonstrate a significant difference in tenure between churned and active customers, highlighting the importance of addressing churn as a key concern for our company. These findings will serve as a foundation for further research and action to improve customer retention and business performance.
