WHAT YOU’LL LEARN TO DO: Create and interpret different types of graphs.
- Distinguish between data sets better suited to line graphs and data sets better suited to bar graphs
- Determine which variable in a data set is the independent variable and should be plotted on the X axis and which variable in the data set is the dependent variable and should be plotted on the Y axis.
- Construct a well-designed graph that conveys the maximal amount of information about the data set with the maximal amount of visual impact.
- Identify the main conclusions that can be drawn from the pattern of data in a graph.
- Draw conclusions about relationships between variables based on correlation coefficients (r values) or based on coefficients of determination (r2 values).
