Data Types
  • Numeric: Continuous or discrete numerical values (shows mean, median, std dev, etc.)
  • Categorical: Text or discrete categories (shows frequency counts, mode)
  • Date/Time: Temporal data (shows range, patterns)
  • Boolean: True/false or binary values (shows proportions)

The app automatically detects data types based on column values.

Summary Statistics
  • Count: Total number of observations
  • Missing: Number and percentage of null/empty values
  • Mean: Average value (numeric only)
  • Median: Middle value when sorted (numeric only)
  • Mode: Most frequent value
  • Std Dev: Standard deviation, measure of spread
  • Variance: Squared standard deviation
  • Min/Max: Minimum and maximum values
  • Q1/Q3: 25th and 75th percentiles
  • Skewness: Measure of asymmetry in distribution
  • Kurtosis: Measure of tail heaviness
Distribution Analysis

The histogram shows the frequency distribution of values:

  • Bins: Data is grouped into ranges for visualization
  • Frequency: Height of bars shows count in each bin
  • Shape: Normal, skewed, bimodal, uniform, etc.

Adjust bin count to see more or less detail in the distribution.

Outlier Detection

Three methods for identifying outliers:

  • IQR Method: Values below Q1 - 1.5×IQR or above Q3 + 1.5×IQR
  • Z-Score: Values with |z-score| > 3 (>3 standard deviations from mean)
  • Modified Z-Score: More robust using median absolute deviation

The box plot visualizes the distribution and highlights outliers.

Use Cases
  • EDA: Exploratory data analysis before modeling
  • Data Quality: Check for missing values, outliers, and anomalies
  • Feature Engineering: Understand variable distributions for transformation
  • Reporting: Generate statistical summaries for stakeholders
  • Data Profiling: Quick overview of individual variables
