Univariate Analysis
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)
Visualization
Plots that can be useful:
- Bar Charts
- Box Plots for visualizing Summary Statistics
- Histograms and Density Plots
