Descriptive statistics

As explained in Machine Learning for Tabular Data: XGBoost, Deep Learning, and AI

Descriptive statistics are numerical summaries that characterize the distribution and central, spread, or other properties of observed data.

Descriptive statistics summarize a dataset’s distribution, central tendency, and spread. For a Kuala Lumpur real-estate DataFrame, df.describe() helps verify which apparently numeric columns contain usable numerical data. section 9.1

Use descriptive statistics to:

  • Inspect numeric columns such as Bathrooms and Car Parks. section 9.1
  • Detect columns such as Price, Rooms, and Size that look numeric but require further processing. section 9.1
  • Compare unique-value counts as an additional indication of continuous or categorical data. section 9.1
df.describe()

Inspect the df.describe() listing alongside its dataset output to connect summary statistics with column validation. section 9.1

How Machine Learning for Tabular Data: XGBoost, Deep Learning, and AI covers it

How deep it goes
Explains distribution, central tendency, and spread through df.describe(), then defers extraction of malformed numeric fields.
Examples
Uses Kuala Lumpur property columns, including Bathrooms, Car Parks, Price, Rooms, and Size.
What you can do after
Diagnose column types and numeric distributions with df.describe() and df.nunique().
How it connects
Connects numeric-versus-categorical classification with unique-value counts and dataset preprocessing.
