Bar Graphs, Histograms, Line Graphs Arizona State Standard – Solve problems by selecting, constructing, interpreting, and calculating with displays of data. S2C1PO1
Objective • I will be able to use a bar graph to represent data. • I will be able to read and construct histograms. • I will be able to use a line graph to represent data.
Bar Graphs • A bar graph uses vertical or horizontal bars to display numerical information. • Bar graphs can be used to compare amounts. • Choose an appropriate scale (with regular intervals). • The bars should have the same width.
Histograms – compare continuous data in intervals • A histogram is a bar graph in which the bars represent equally spacedintervals of numbers (you must decideon your equal intervals). • There are no spaces between the bars on the histogram. • Make a frequency distribution & use the totals to create the histogram

Line Graphs • Line graphs show trends over intervals of time. • Line graphs can have one line or several lines.
