Differentiate between continuous and discrete data, and determine ways to represent those using graphs and diagrams.

Remarks

For instance, if growth of a plant over time is measured, the data is continuous because time is measured continuously and a line graph is appropriate. However, if the number of students present in the classroom per day is recorded, these data are discrete (countable) and a bar graph is appropriate.

 

Students may use a Venn Diagram to represent a data set.
