Customer Satisfaction Survey Heatmap
Correlation heatmap for customer survey data with Likert scale ratings (1-10). Analyzes relationships between product quality, service, shipping, price value, and overall satisfaction. Demonstrates handling of ordinal survey data with smaller sample sizes.
Input
What you provide to the skill

CORRELATION ANALYSIS RESULTS
Dataset: 83 rows x 5 columns
Numeric variables analyzed: 5
Variables: product_quality, service, shipping, price_value, satisfaction
Strong Correlations Found: 10 (|r| > 0.7)
product_quality <-> service r = 1.000 (positive)
product_quality <-> price_value r = 1.000 (positive)
product_quality <-> satisfaction r = 1.000 (positive)
service <-> price_value r = 1.000 (positive)
service <-> satisfaction r = 1.000 (positive)
price_value <-> satisfaction r = 1.000 (positive)
product_quality <-> shipping r = 0.939 (positive)
service <-> shipping r = 0.939 (positive)
shipping <-> price_value r = 0.939 (positive)
shipping <-> satisfaction r = 0.939 (positive)
Multicollinearity Issues: 10 (|r| > 0.8)
WARNING: High correlations detected between predictors!
Consider removing or combining these variables for regression modeling:
- product_quality <-> service (r = 1.000)
- product_quality <-> price_value (r = 1.000)
- product_quality <-> satisfaction (r = 1.000)
- service <-> price_value (r = 1.000)
- service <-> satisfaction (r = 1.000)
- price_value <-> satisfaction (r = 1.000)
- product_quality <-> shipping (r = 0.939)
- service <-> shipping (r = 0.939)
- shipping <-> price_value (r = 0.939)
- shipping <-> satisfaction (r = 0.939)
