Create a Graph - click here for an introduction to an online program where you can create a simple graph
Data Grapher - another app for creating graphs online that you can print in colour
GRADE 4: You are going to create a survey question and collect, then display PRIMARY DATA.
GRADE 5: Your project is to look for SECONDARY DATA about a subject that interests you. You will create a graph to show the data.
Where can I find data?
1. We have books about Canada in our classroom filled with data.
2. Sometimes you can find charts of data in books such as The Guiness Book of Records.
3. Try some of these websites:
-THE CANADIAN ENCYCLOPEDIA

CONTINUOUS DATA
-any value within a range
-ex: time in a race, temperature, weight
-use a continuous line graph
-what can be measured
DISCRETE DATA
-only certain values available
-ex: number of students in a class
-what can be counted
- use a broken line graph
-the line is dotted or dashed
