2. BAR GRAPHS Using data to make graphs

3. WHAT IS DATA? It is information. An example: In my fifth grade class we took a pizza lovers survey. We learned that ten kids liked pepperoni pizza best. Nine kids liked sausage pizza best. Seven kids liked cheese pizza best. This information is called DATA. If a mom was planning a pizza party for the class, she would need the pizza lovers survey DATA. I need to order 10 pepperoni, 9 sausage and 7 cheese pizzas.

4. Your report card is another example of data. Math: 88% Reading: 94% Science: 75% Social Studies: 80% Language Arts: 55% My Language Arts teacher may not like me. WE USE GRAPHS TO ORGANIZE DATA. I know my parents will want to talk to my Language Arts teacher.

5. A CHALLENGE. Which bar on the graph represents 45 feet? Feet

6. Cows124 Chickens450 Turkeys388 Horses56 Mules110 THIS IS THE INFORMATION OR DATA…AND WHAT ABOUT THE GRAPH? Animals on the farm Chickens rule!

7. DATA WITH A GRAPH. Cows124 Chickens450 Turkeys388 Horses56 Mules110

8. KIDS HAVE PETS: Salomon asked the kids in his class what kind of pet they have. This is the data he collected.

9. Building a bar graph using this data helps us easily compare the number of pets kids have. All four (4) parts of a bar graph must be present for the graph to be complete. Labels Title Bars Scale

10. ANSWER THE QUESTIONS 1. which animal most kids have as pets?. 2. Which two kinds of animals are owned by the same number of kids? 3. How many kids have either a dog or a cat? 4. The numbers up the side of the bar graph are called the ________.

12. HOW CAN YOU COLLECT THE INFORMATION NEEDED TO CONSTRUCT A BAR CHART? BY MAKING A FREQUENCY TABLE FIRST! A Frequency table is a table that lists each item in a data set with the number of times it occurs.

13. YOUR TURN!  1. Ask 10 students the following information and complete the table. FLAVOUR TALLY Insert any other flavours here

14. 2. Construct your own frequency table CRISPSTALLY FREQUENCY 3. Make a a bar graph showing the favourite crisps in our class.
