1. Data and Graphs

2. DAY 1: Introduction Student will learn the parts of a graph. Student will decide when to use a line graph and when to use a bar graph.

3. What is DATA DATA is a collection of facts -ex: The height of all students in 5B -The favorite food of all students in 5B -The average temperature in Concepcion from 1950 to 2011 -The percent of people without jobs every month

4. How to Represent Data 1)In a table: ClassTotal number of students 4 A22 4 B18 5 A21 5 B19

5. 2) In a bar graph Number of students in grades 4-5 Class Number of Students

6. 3) In a line graph Number of Students Class

7. Number of students in grades 4-5 Class Number of Students Graph title Data group axis Frequency axis Bars Scale

8. Graph Vocabulary Graph title: This explains what data a graph shows Axis: The two sides of a graph Groups Data Axis: shows the type of data being displayed (it is usually on the bottom) Frequency Data Axis: this axis has a scale and shows the quantity in each groups (it is usually on the side) Scale:it is on the Frequency Data Axis. The scale shows the numbers from the lowest to the highest Interval: How many numbers the scale increases by each time there is a line

9. Scale vs Interval The SCALE is 0-25 students The INTERVAL is 5 Number of Students Class

10. How to describe a graph Trend: a pattern in a graph. Increase: to go up Decrease: to go down

12. Bar graph OR line graph??? Bar graph: It is used to show differences in many types of data Line graph: It is used to show how one thing changes over time

13. In the following situations we will decide: -Should we use a line graph or bar graph? -What trends do we see in the graph?

14. I want to show students’ favourite colors (red, blue, green, black, pink) How many students like each color Should I use a line graph of a bar graph?

16. I want to show how much money people make in different regions of Canada

18. I want to show change in the temperature of a place from Day 1 to Day 14

20. I want to show how many people did not have a job between 1989 to 2008

22. I want to show the population in the five largest countries in South America

24. I want to show how the population of Chile has changed in the past 10 years.
