Collecting and Organizing Data • What is data? • Data is information collected about people or things. There are many different ways to show collected data. We will be learning about data by exploring four different ways to organize and display data. The four ways are listed below. • Pictographs • Line Graphs • Bar Graphs • Frequency Tables
Pictographs Use pictographs to compare data. Great for surveys like: What is the most popular food? What is the most popular pet? What sports are played the most? Which cookies do 4th graders prefer?
Number your paper like this: 1. 2. 3. 4. ******* 1. 2. 3. 4. 5. 6. ******** 1. 2. 3. 4. 1. 2. 3. 4. 5. 6. ****** 1. 2. 3. ****** 1. 2. 3. 1. 2. 3. 4. 5. ****** 1. 2. 3. 4. ****** 1. 2. 3. 4.
There are questions on each page. Answer the questions using your numbered sheet of paper.
Pictographs A pictograph uses pictures to display data. A pictograph also uses a key. In this pictograph, one apple image represents 10 apples. • Use the graph above to answer the following questions. • 1. How many Golden Delicious Apples are there? • How many McIntosh Apples are there? • What type of apple appears less than 30 times (less than does not include 30)? • How much does half of an apple represent? http://www.highpointsmath.com/sitemap/images/clip_image001_054.gif
Sports played by 3rd graders Baseball-50 Soccer-60 Hockey-20 Basketball-40 Football-25 Gymnastics-15 • Use the graph above to answer the following questions. • How many 3rd Graders play soccer? • Which sport is played the least? • Which sports have less than 40 students? • If there was a half of a soccer ball on the key, how many students would it represent? • Look at the data on the left. Does the graph accurately represent the data? • How would you fix the mistakes? How would you change the graph to represent the data accurately?
Line Graphs Use line graphs to track changes over time. They can also be sued to find trends in data. Sometimes to sets of data can be used. Great to show data like: Sales over a period of time Temperatures over a period time Populations over a period of time
Use the graph above to answer the questions below. • What kind of graph is this? • How much time does it measure? • What is the interval between kilograms (kg)? • If this trend continues, how much will Sam weigh at the beginning of June?
Use the line graph to the right to answer the questions below. • What does this graph show? • If you wanted to go to the store when the fewest people would be there, what would be the best time to go? • What time are the most people at the store? • If this trend continues, how many people would be at the store at 7 pm? • During what one hour interval did the greatest change of people in the store occur? • During what one hour interval did the number of people in the store stay consistent?
Bar Graphs and Double-Bar Graphs Use to compare data. Double-bar graphs can be used to compare two sets of data. Great to use to display data like: Temperatures in different cities Sales of different objects Populations of different cities

Use the chart above to answer the questions. • Which graph tracks changes over time? • Which graph is used to find trends in data? • When do you use a pictograph? • What is the difference between bar graphs and double-bar graphs?
