Data Analysis Protocol
1. Introduction
-
Objective: The purpose of this data analysis is to evaluate the impact of a new marketing campaign on customer engagement and sales. We aim to determine whether there is a statistically significant increase in customer interaction and revenue after the campaign's launch.
-
Background: The data was collected from customer interaction logs and sales records over a six-month period before and after the campaign. Previous studies have shown mixed results regarding the effectiveness of marketing campaigns on customer behavior.
2. Data Description
Data Source: Data was sourced from the company's CRM system and sales database.
The dataset includes:
-
Customer Interaction Logs: Timestamped records of customer activities on the website, including page views, clicks, and time spent.
-
Sales Records: Transaction data including date, product ID, quantity sold, and revenue.
Data Structure:
-
Customer Interaction Logs: 50,000 records with variables: CustomerID, Date, PageViews, Clicks, TimeSpent (minutes).
-
Sales Records: 30,000 records with variables: TransactionID, Date, ProductID, Quantity, Revenue.
Data Cleaning:
-
Handle missing data by imputation for interaction logs and exclusion for sales records.
-
Outliers will be identified using z-scores and addressed accordingly.
-
Data will be normalized where necessary, particularly in time spent and revenue.
3. Analysis Plan
Descriptive Statistics:
-
Calculate mean, median, and standard deviation for interaction metrics (PageViews, Clicks, TimeSpent) and sales metrics (Quantity, Revenue).
-
Use frequency distributions to analyze customer activity patterns.
Inferential Statistics:
-
Conduct a t-test to compare mean sales before and after the campaign.
-
Perform regression analysis to assess the relationship between customer interactions and sales revenue.
-
Use chi-square tests to evaluate any significant changes in categorical variables such as customer segments.
Data Visualization:
-
Histograms for distribution of page views and time spent.
-
Scatter plots to show the relationship between customer interactions and sales.
-
Bar charts comparing average sales before and after the campaign.
Software and Tools:
-
Data analysis will be performed using R for statistical testing and Python for data manipulation.
-
Visualizations will be created using Tableau for interactive dashboards and matplotlib for static graphs.
4. Assumptions and Limitations
Assumptions:
-
Data is normally distributed for t-tests.
-
Linearity in regression analysis.
Limitations:
-
Potential bias due to incomplete customer logs.
-
Generalizability may be limited to similar marketing campaigns and customer demographics.
5. Ethical Considerations
-
Data Privacy: All customer data will be anonymized before analysis to ensure privacy. Sensitive information such as customer names and contact details will be removed.
-
Informed Consent: Participants provided consent for their data to be used for analysis as per the company’s privacy policy.
6. Quality Assurance
-
Validation: Perform cross-validation of regression models to assess accuracy and robustness.
-
Reproducibility: All analysis code will be documented and stored in a version-controlled repository (GitHub) to ensure reproducibility.
7. Reporting
-
Format: Results will be presented in a comprehensive business report, including an executive summary, detailed analysis, and visualizations.
-
Interpretation: Results will be interpreted in the context of campaign effectiveness and recommendations will be provided based on statistical findings.
-
Visualizations: Visualizations will be integrated into the final report to illustrate key findings and trends.
