What is a divided bar chart?

A single bar split into sections, each section showing one category's share of the whole (sections total 100%).

What are the steps to complete a pie chart from percentage data?
e.g. add a sector for 25%

1. Change the percentage to degrees (multiply by 3.6): 25 × 3.6 = 90°
2. Measure that angle from the existing line with a protractor and draw the sector.
3. Shade or label the sector to match the key.

Which type of graph should be used to show the relationship between two sets of data?
e.g. GNI per person and food consumption per person

A scattergraph, with a line of best fit drawn through the centre of the points.

How is a histogram different from a bar chart?

A histogram shows continuous data grouped into equal class intervals along a continuous scale, so its bars touch with no gaps between them.
