Interpreting relationships from scatterplot data
Each set of data presented in a scatterplot shows a relationship of some sort. When the dots are very close together in a line, they tend to have a close relationship, when they are further apart and almost ‘random’ in their placement, there is either little or no relationship. The following post will explain reading a scatterplot and interpreting relationships in the HSC Standard Math course using :
- Forms of an association (linear and non-linear form)
- The direction of an association (positive or negative)
- The strength of an association (strong, moderate or weak)
- The independent and dependent variables
How do you interpret scatterplots?
The following video explains how to interpret scatterplots, and goes through each of the above dot points!
Relationship: Strength, form and direction
The following video explains how to identify the strength, form and direction of relationships in scatterplots.
The following video provides an example of identifying the strength, form and direction of relationships.
Relationship: Dependent and Independent variables
The following video explains dependent and independent variables in more detail.
