Census @ School Data

Today we will be looking at data and then graphing it on Numbers. We will be learning about what graphs are appropriate to use for different data sets.

1. Your task is to visit the following website  Census @ School

2. Look at Table 1: Eye colour. Enter this data onto Numbers and use it to create a graph you think is appropriate. Explain why you chose that particular graph and why you think it best displays this data.

3. Look at Table 11: Method of travel to school by state. Enter the date for Victoria onto Numbers and use it to create a graph you think is appropriate. Explain why you chose that particular graph and why you think it best displays this data.

4. Pick any other set of data from another table on this website. Enter it onto Numbers, graph it and explain why you chose that particular graph and why you think it best displays this data.

Comparing Graphs

Below I have created a number of graphs using the same data. The data used was how many points a football team scored in the first 6 weeks of the season.

When we collect data we need to make careful choices about to represent it and which graphs are appropriate to use.

Your task is to look at the graphs below and give reasons why particular graphs might or might not be helpful to answer a question about this data set. Good luck 🙂
