Types of Graphs

Hello and welcome, class! Today we will be looking at types of graphs or charts.

1. Line Charts

I would recommend line charts for investigating trends, such as 'How many people play basketball in the last 2 years?' or something similar to that. Line charts can be sometimes difficult to read for a beginner, therefore I would only recommend using this chart if you are very confident with APDD.

2. Bar Graphs

This is the most used type of graph in the APDD community, as it is clear, straight to the point and easy to read. Bright (but not too contrasting and saturated) colours are also very important with bar graphs, as it makes it even more easy to read. This is recommended if you want to get straight with the point with the general and overall data.

3. Pie Charts

This sort of chart is a bit harder to make as you need to calculate the sizes of the sections of the percentages on the pie chart. Again, this type of graph is useful when you only want to see the overall data, just like the bar graph.

4. Pictograph

I would not recommend this type of graph at all, as it usually looks messy and unprofessional. Please do not use this one for homework or exams!!

5. Treemaps

Treemaps are a very creative way of presenting data, but for some beginner students in APDD it may be hard to understand or get a grasp of. I wouldn't particularly recommend this myself, but individuals may think otherwise.

6. Area Charts

Area charts can be hard to figure out at first, but as you look at it more you may figure it out. I wouldn't recommend this one but you are free to use it if that's your choice.

Which type of graph do you prefer?

I hope to see you next lesson!
