Big Ideas:
Large amounts of data can be organized into intervals.
Histograms are used to represent data that is continuous and so there are no spaces between the bars of a histogram.
Dot plots and histograms that display the same data will have data shapes which are similar.
The shape of a set of data can give us information.
The type of data determines how it is organized, represented and displayed. This lesson focuses on representing a large quantity of continuous data using equal-sized intervals on a dot plot and a histogram. Students are asked to look at the shapes of the data produced by the plot and the graph. Conclusions can be drawn from the shapes of the data.
Vocabulary: data, frequency table, interval, dot plot, histogram, shape of data
