TLF ID:
L5857
Year level:
5–9
Series description:
Students explore the characteristics of scatter plot graphs and use a line of best fit to identify if there is a positive, negative or no clear relationship between two variables.
Learning object description:
Students are introduced to the features of scatter plot graphs and learn how to construct and interpret them. Students enter their personal data and plot it with other data on a graph. They use a line of best fit to identify if there is a positive or negative relationship between the two variables. This learning object is a combination of five objects in the same series.
Key learning objectives:
- Students explore the characteristics and uses of scatter plots.
- Students use a scatter plot to identify if there is a positive or negative relationship between a pair of variables.
- Students interpret bivariate data in tables and graphs.
Educational value:
The learning object:
- introduces students to the features and uses of scatter plots;
- helps students to choose axes and scales while constructing a scatter plot;
- enables students to enter personal data for a statistical investigation;
- dynamically displays data values on a scatter plot;
- relates experimental conclusions to patterns in scatter plots.
Learning area:
Mathematics
Keywords:
Axes, Continuous data, Data analysis, Line of best fit, Scale (Mathematics), Scatter graphs
