Correlation Analysis
I performed a correlation analysis to understand how different advertising channels influence product sales. The heatmap highlights the strength of the relationship between advertising spend and sales.
Key Findings
TV advertising shows the strongest positive correlation with Sales (0.78), indicating that increased TV advertising is strongly associated with higher sales performance.
Radio advertising has a moderate positive correlation (0.58) with Sales, suggesting it also contributes significantly to revenue generation.
Newspaper advertising exhibits a weak positive correlation (0.23) with Sales, implying that it has a relatively smaller impact compared to TV and Radio.
The advertising channels themselves have low inter-correlation, indicating minimal multicollinearity and making them suitable for predictive modeling.
The 'Unnamed: 0' column was identified as an index column and removed during data preprocessing to ensure accurate analysis.
Business Insights
TV advertising should be prioritized when the objective is to maximize sales, as it demonstrates the strongest relationship with revenue.
Radio advertising can serve as an effective complementary marketing channel.
Newspaper advertising may require budget optimization or strategic reassessment due to its comparatively lower influence on sales.
Conclusion
The correlation analysis reveals that TV advertising is the most influential factor affecting sales, followed by Radio, while Newspaper advertising has a limited impact. These insights can help businesses allocate their marketing budget more effectively and support the development of predictive sales models.
