Compound Bar Chart

A bar chart where the categories are stacked on top of each other. This allows for the visualisation of the proportion of each category each represents. Usually used when comparing two or more sets of data. A key is needed to interpret the data.

Correlation

The type of relationship two variables have with each other. Positive correlation is where as one variable gets larger, so does the other. Negative correlation is where as one variable gets larger, the other gets smaller. No correlation tells us that the variables are not linked.

Example: This graph shows positive correlation.
