Segmentation Analysis using PCA and K-means

The summary statistics for the credit score data provide valuable insights into the distribution of scores within the dataset. Key observations are as follows: Symmetry: The mean credit score (650.5) and median credit score (652.0) are very close in value, indicating an approximately symmetric or bell-shaped distribution. This symmetry suggests a lack of extreme skewness, with credit scores evenly distributed across the range rather than heavily skewed towards low or high values. Range: The credit scores range from 350 to 850, covering almost the entire possible range for credit scores (typically 300 to 850). This wide range demonstrates that the dataset includes a diverse representation of credit scores, from poor to excellent. Spread: The interquartile range (IQR) of 134 indicates a moderate spread in the middle 50% of the data. While the central portion of credit scores is relatively concentrated, there are still substantial variations within this range. Overall Distribution: Based on the summary statistics, the distribution of credit scores appears to be proportional and balanced, without extreme fluctuations or skewness. This proportional representation of credit scores across the range suggests that the dataset is representative of the population being studied. In summary, the symmetric shape, wide range, and moderate spread of the credit score data indicate a well-balanced and diverse distribution. This balanced representation enhances the validity and reliability of any analyses or conclusions drawn from this dataset.
