Activity 2 - Collecting data
Activity 2 - Collecting data
Data can be collected in many ways. The simplest way is direct observation. Surveys are a method of collecting data. You can survey:
people (through questionnaires, opinion polls, etc)
things (like pollution levels in a river, or traffic flow).
When we conduct a survey, we can perform a census or a sample.
A census is when we collect data for every member of the group (the whole “population”).
A sample is when we collect data just for selected members of the group.
A census is accurate, but hard to do. A sample is not as accurate, but may be good enough, and is a lot easier and cheaper.
In Australia, the Australian government, through the Australian Bureau of Statistics, conducts a census of the Australian population every 5 years. Information collected helps the Australian government to make decisions about spending money (such as where to build hospitals) and providing necessary services (such as health and education). We had one earlier this year.
Example:
There are 120 people in your local football club.
You can ask everyone (all 120) what their age is. That is a census.
Or you could just choose the people that are there one afternoon at training. That is a sample.
