Continuous Variables (Univariate Analysis)
This main module allows you to perform comprehensive descriptive statistics on continuous numerical data. Before exploring the individual summaries, you must first define the variables you want to analyze using the left sidebar panel.
1. Select Your Variable
- Use the Select Quantitative Variable dropdown menu in the sidebar to choose the continuous variable you wish to analyze from your loaded dataset.
2. Grouping Data (Optional)
- If you want to compare statistics across different categories, check the Statistics by group? box.
- Once checked, a new dropdown menu will appear titled Group by. You can select up to a maximum of two categorical variables to partition your data.
3. Navigate the Analysis Tabs
- After setting up your variables in the sidebar, use the main panel on the right to navigate between the three analysis tools:
- Numerical Summary: Calculate central tendency, dispersion, shape, and relative positions.
- Tabular Summary: Generate frequency tables using automated binning rules.
- Graphic Summary: Visualize your data with histograms, boxplots, violins, and more.
Graphic Summary Module
The Graphic Summary tab allows you to visualize your data using various statistical plots. Follow these steps to generate, style, and export your charts:
1. Select Graph Type
- Use the Select dropdown menu to choose your desired chart: Histogram, Density, Boxplot, Violin, Polygon, or Ogive.
- Toggle the Horizontal switch if you want to flip the plot's orientation.
2. Customize Your Graph
- Click the Customize graph button (marked with a fish icon) to open the styling panel.
- Styling Options: Depending on the graph type and whether your data is grouped, you can adjust:
- Structure: Adjust the number of Bins (for Histograms/Polygons) or toggle specific features like Notch (Boxplots) and Trim (Violin plots).
- Aesthetics: Modify Themes, Fonts, Palettes, Line Widths, and Colors (Fill, Line, Outliers, Points).
- Labels: Rename your axis titles using the xlab and ylab fields.
- Reset: Click the yellow Reset to Initial State button at any time to undo your customizations.
3. Export & Extras
- Download: Click the blue Download Graph button to save your customized visualization to your computer.
- Outlier Table: If you are viewing a Boxplot, scroll down to see a detailed data table listing any calculated outliers.
