Analysis (mostly exploratory) of one variable

- order of magnitude of this variable
- are there missing values?
- Outliers and extreme values?

In order to analyze one variable

- Calculate Summary Statistics
- Also can calculate Mean and Standard Deviation
- Use Histograms to learn about data Distribution

Results can be used for

- deciding how to discretize this variable
- Handling Missing Values
- Noise Handling (Data Mining)

Plots that can be useful:

- Bar Charts
- Box Plots for visualizing Summary Statistics
- Histograms and Density Plots
