The ability to analyse, interpret and evaluate statistical information
Communicating statistical information and understandings
4. Overview
This classroom activity involves comparing student connection to the Internet in 2006 to now. Students can determine the present day use either by conducting their own survey to collect data or by using the this year's CensusAtSchool data (using a sample of Australian students from the Random Sampler that compares common questions only). In this activity students are asked to conduct a simple analysis using graphs to describe how access to the internet has changed.
5. Requirements
Computer with internet connection
Spreadsheet software
Calculator
Pens and paper
Student Worksheet
6. Instructions
The world of computers changes very quickly. The Internet is a good example. Viewing and uploading videos on YouTube is common now, but prior to 2006 YouTube did not exist! Most people didn’t have broadband either, so even if YouTube had existed not many could have used it.
6.1 Is it true that most students did not have broadband in 2006?
You can find out using a data sample from the 2006 CensusAtSchool Random Sampler. The records of over 112,000 students are in this 2006 database.
6.1.1 Get a sample from the random sampler.
Reference year: 2006
Select questions: All
The random sample you get is an Excel spreadsheet of raw data. Question 6 asked "Can the Internet be accessed at your home?"
Be careful to ensure you use the sheet with the label 2006.
6.1.2 Count each response in your sample and record it in a table like the one below:
( Hint: It will be easier to count the number of students in each category if you sort the data first. If you are good at Excel it will be even easier if you use the COUNTIF function to do the counting for you)
Type of Internet Access
Number of Students
Percentage of Students
No Internet connection
Yes - broadband
connection
Yes - dial-up connection
Yes - other (include
Internet access through
mobile phone etc)
Total
6.1.3 Use a graph to represent the table above. This can be easier to understand.
6.1.4 Decide if most students had access to Broadband Internet in 2006. You can use the table or graph to help you decide.
6.2 Do most students have broadband today?
One way to answer this question would be to collect your own data.
6.2.1 You could do this by conducting a survey of your own class and recording the data you collect. Use the question exactly as it is written in the 2006 CensusAtSchool questionnaire.
6.2.2 Use your data to prepare a table and graphs (clearly label 'Current Year') similar to those you prepared for 2006 data.
6.2.3 Decide if most students have access to Broadband Internet today. You can use the table or graph to help you decide
(An alternative to conducting a survey would be to use the second sheet (label 'Current Year') of the sample you took earlier. Or you could take a new sample:
Reference year: Current Year
Select questions: All
6.3 Questions:
6.3.1 Do you think that your class results could be used to represent the people who live in your neighbourhood?
6.3.2 Describe a sample that could be taken that could better represent your neighbourhood.
7. Extension
7.1 Investigate the access to broadband in your neighbourhood by viewing the 2006 Census Data. You can do this by using the Community Profiles from the 2006 Census.
7.3 Learn more about surveys by playing the Home Internet Surveygame. You may have to turn up the magnification on your computer to view the activity clearly.
