  3. Steps

  4. Step 1 make a frequency table • First you have to decide on a topic (we chose how many pizza slices you can eat in one sitting) • Then ask a group of people your question • While they answer put the data into a table by putting all the answers on one side then the number of people on the other

  5. After step 1 You should have this at step 1

  6. Step 2 decide on an interval • An interval is an increment of numbers your data will go up by • It all depends on your data if you had 100 answers then your intervals could be by 10 • For ours we had up to 36 was our highest number so are intervals were by 6

  7. Step 3 Make a new chart with intervals on one side and tallies on the other • This is pretty self explanatory but just in case… • You just want to make a normal chart and put each interval on one side (for example: 1-6, 7-12, 13-18.. so on) • Then count how many people answer in each interval and put that many tallies or just the number

  8. Step 4 Pick a title for your graph • Your title should say something about your question and sometimes your group of people you asked • Ours was Number of pizza slices Mrs. Clark’s AA class can eat in one sitting

  9. Step 5 Put your intervals on the horizontal axis • Again self explanatory • You want to make sure that your intervals are on the right axis because if you put them on the vertical axis • You would not be able to graph the intervals

  10. Step 6 label your intervals • You should label your intervals on what your question was asking • For ours we had Number of Slices

  11. Step 7 Pick a number to go up by on the vertical axis • First you have to pick a number that can evenly go into it • You do not want such a small number that your graph will be huge • But you don’t want the numbers to be to big , then your graph will be to small • It should go up to the biggest number people in a interval • For our graph we went up by 5 because we had a total number of 28 people answering a 23 being the biggest bar

  12. Step 8 Label your vertical axis • This should be the people you surveyed or just frequency works • On our graph we had number of people

  13. Step 9 Count up the tallies per interval and make a bar • Pretty explanatory • Just take your time when marking it between the intervals try and make it as close as possible

  14. Step 10 Do for all others. Be sure bars touch one another • To be classified as a histogram the bars must touch

  15. This is the final product
