Decide how many bars you will include in the histogram. List the range of the bar values and the corresponding frequency in the table. Remember that each bar should contain the same number of values. (Note: You may leave some rows blank or add more rows depending on the number of bars your histogram will contain.) Range of Bar Values Frequency b. Draw a histogram to represent the data set. Be sure to include a title, labels indicating the bar values along the x-axis, labels for the bar height values (frequency) along the y-axis, and bars drawn to the appropriate heights © K12 Inc. 2.

(Note: You may leave some rows blank or add more rows depending on the number of bars your histogram will contain.) Range of Bar Values Frequency b. Draw a histogram to represent the data set. Be sure to include a title, labels indicating the bar values along the x-axis, labels for the bar height values (frequency) along the y-axis, and bars drawn to the appropriate heights Part II: Find Data to Create a Histogram Next, search the internet to find a real-world data set that can be graphed as a histogram. The following Web sites are good places to look for data if you’re not sure where to start. http://2010.census.gov/2010census/ http://www.nationalparkstraveler.com/2012/03/ranking-national-parks-visitation20119573 a.
