  3. Line PlotMethod of drawing a line plot • If numbers are used: Order the values from least to greatest. (Note: some numbers may repeat). • If words are used: place data into categories. • Draw a number line and label with the values/categories above (only use repeated numbers/category once). • Plot the values of each item on a number line by placing an X above the value which it corresponds. • Continue to plot the values until all data is used. Repeated numbers: the X is placed vertically above the previous X. (See example next slide).
