Let’s See how we would put one together!

Step 1: Survey students. Record the results.

Step 2Frequency Table • Make a frequency table of the data. Be sure to use equal intervals

Step 3Make histogram • Choose an appropriate scale and interval for the vertical axis. The greatest value on the scale should be at least as great as the greatest frequency.

Step 4 • Draw a bar for each interval. The height of the bar is the frequency for that interval. Bars must touch but not overlap. • Label the axes and give the graph title

Final Product!

Question of the Day? What is the difference between a histogram and a bar graph?
