The Correlations tab is designed to help you visualize the relationship between two different financial variables. It allows you to plot one metric against another to identify patterns or spot outliers.
Select Variables Tab
To generate a chart, you must configure the variables for the axes independently. The selection area is divided into three collapsible sections:
- X-Axis Variable: Determines the horizontal axis.
- Y-Axis Variable: Determines the vertical axis.
- Bubble Size (Optional): Determines the size of the dots.
To select your data, click on a panel to expand it, and then follow the steps below inside each panel:
Step 1: Choose a Source Table
Use the dropdown menu labeled “Source Table” to choose the broad category of finance you are interested in for this specific axis (e.g., Table 1 - Consolidated Statement of Comprehensive Income and Expenditure).
Note: You can pick different source tables for the X-axis and the Y-axis.
Step 2: Navigate the Hierarchy
Use the hierarchical tree below the dropdown to drill down into the specific financial metrics.
- Expand/Collapse: Use the buttons to open or close all folders, or click on the triangles next to folder names to open individual folders.
- Search: Type in the search bar (e.g., “Tuition”) to instantly find specific variables within the tree.
- Select: Click on a specific sub-variable to select it.
Visualisation Tab
Once your variables are selected, switch to the “Visualisation” panel to view and refine your chart.
Academic Year
Unlike the Trends tab, which shows history, the Correlations tab looks at a specific snapshot in time. Use the Academic Year selector to choose which financial year to analyse.
Unit Selection
Comparisons between large and small universities can be misleading if you only look at raw numbers. Use the Data Units selectors to normalise the data for the X and Y axes independently:
- Raw Values: Shows the actual value (e.g., £ millions). Good for seeing absolute scale.
- Per Student FTE: Divides the value by the number of Full-Time Equivalent students. Useful for comparing “spend per student.”
- Per Staff FTE: Divides the value by the number of Full-Time Equivalent staff.
- Percentage of Total Income/Expenditure: Shows the value as a share of the university’s total finances. Useful for understanding financial priorities (e.g., “What % of income comes from research?”).
These controls help you interpret the scatter plot:
- Show Hover Tooltips: Controls the popup boxes that appear when you move your mouse cursor over a dot. Uncheck this if you want a cleaner view.
- Show Trend Line: Adds a dashed line of best fit. This helps you identify if there is a general correlation between your two variables.
- Log X/Log Y: Switches the axes to a logarithmic scale.
Main panel
Understanding the Chart
The chart displays a scatter plot of your selected universities.
- Dots: Each dot represents one university.
- Size: If a “Bubble Size” variable was selected, larger dots represent higher values for the bubble size variable.
Interactive Chart Features
The chart is interactive to help you explore the data:
- Hover: Move your mouse over a dot to see the university name and the exact values for the X, Y, and Size variables.
- Box Zoom (top right): Click and drag your mouse to draw a box around a specific cluster of universities to zoom in.
- Slider Zoom: Use the sliders at the bottom and the left side of the chart to zoom in.
- Legend: Click on a university’s name in the legend to hide or show its dot. Hover over a name to highlight just that university.
- Download: Click the “Save as Image” camera icon (top right of the chart) to download a
