Two Ways to Gather Information
With your kind teacher Mrs. Brenda β€οΈ
Today weβre learning about two important types of data:
Primary Data and Secondary Data.
Understanding the difference helps us become better researchers and thinkers!
Data you collect yourself!
Examples:
β’ Surveying your classmates about favourite sports
β’ Measuring how long it takes friends to run 100m
Data someone else collected
Examples:
β’ Population of Canada from Statistics Canada
β’ Weather records from Environment Canada
| Primary Data | Secondary Data | |
|---|---|---|
| Advantages | Up-to-date, exactly what you need | Fast, cheap, lots of information |
| Disadvantages | Takes time and effort | May be old or not exactly what you need |
Question 1
You ask your friends what their favourite video game is. Is this primary or secondary data?
Question 2
You look up the population of Toronto on the Statistics Canada website. Is this primary or secondary data?
Question 3
When is it better to use primary data instead of secondary data?
β’ Scientists collecting temperature data in the Arctic = Primary
β’ Students using census data for a project = Secondary
β’ Hockey teams tracking player statistics = Primary
β’ News reports using government data = Secondary
Wonderful job! You understand the difference between primary and secondary data and when to use each.
Try collecting some primary data from your family this week!
Love and curious high-fives,
