- Sample Correlation
The new V4 Scatter Matrix method enables indicators to be analysed against each other and explorer relationships between selected indicators.The scatter matrix is linked to the scatter plot and is a dynamic way to control the scatter plot with immediate response time. By a simple mouse click on any of the small scatter plots in the scatter matrix view - the scatter plot is instantiated with the corresponding vertical and horizontal indicators. This makes the scatter matrix an innovative interactive method to drive the scatter plot.
By hovering over a Scatter Plot in the Scatter Matrix you will get a tooltip showing the indicators that are being visualized in the current Scatter Plot as well as a "Sample Correlation" value. The "Sample Correlation" value indicates how much the two indicators are correlated. This value can span between -1 (a 100% negative correlation) to 1 (a 100% positive correlation). All values closer to 0 will indicate a lower correlation, and 0 corresponds to no correlation at all. Snapshot 2 shows the indicators "Population ages 65+" and "Old-age dependency rate" which has the "Sample correlation" value 1, compared to the Initial view that has the "Sample correlation" value -0.8.
