Lesson Plan: Data representation Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to represent and analyze data using dot plots and line graphs.
Students will be able to
- construct dot plots and line graphs from a given data set or table,
- analyze data given as a dot plot or line graph or by constructing the relevant graph,
- understand that a line sloping upward represents an increase in a line graph and a line sloping downward represents a decrease in a line graph,
- recall that the mode of a data set can be found from a dot plot and line graph,
- identify outliers from a dot plot and line graph.
Students should already be familiar with
- data sets and tables,
- variables and types of data,
- measures of central tendency and outliers.
Students will not cover
- frequency tables, histograms, and bar graphs,
- comparing multiple data sets using dot plots or line graphs.
