Frequency Tables Histograms

Frequency-How often something happens. Frequency Table- A way to organize data in equal intervals. Histogram- Shows how frequently data occurs within equal intervals

Making a Frequency Table 1. Make A title 2. Draw a table with three columns 3. List your choices in the left column 4. In your second column title frequency, and tally the results for each choice. 5. In your third column total the tally for each choice.

Example Histogram

Making a Histogram 1. Draw the axes. Label each axis. 2. Choose and list the intervals for the horizontal axis 3. Create a scale and choose appropriate intervals for the vertical axis. Label each Axis 4. Draw Bars for interval on the horizontal axis. Do not leave spaces between the bars. 5. Give the Graph A title
