Interpreting Data
LG: to interpret and compare data displays Slide2
What does it mean to interpret data displays?
When we collect data, we use graphs and tables (displays) to help us organise the data to make it easy to understand and read.
When we are interpreting the data, we ask ourselves these questions:
What is this data about? Where do we look to find this?
What information does the y axis represent? What information does the x axis represent?
What can we learn from this data? What overall conclusions can we draw?
Evaluate: Is the graph clear and easy to understand? Slide3
Hawthorn History Data
On the next few slides there are 3 data displays. A sample of people from Hawthorn were surveyed. Can you work out what the question might have been?
Read the data display and then answer the questions in your books. Make sure you number each of your answers. Slide4
1a: What might the survey question have been? When was it asked?
1b: What is the information on the x axis? What is the information on the y axis?
1c: Why are there 2 different coloured columns?
1d: How many people were surveyed altogether?
1e: How many men were surveyed? How many women were surveyed?
1f: What do you notice about the ‘clerk’ job?
1g:What do you notice about the survey results? Slide5
2a) What is the different between this graph and the last? Identify
3 things.
2b) How many jobs were there in total?
2c) How many people were surveyed altogether? How many women? How many men?
2d) What is the difference between the ‘home duties’ in 1919 and this year?
2e) What is the difference between the ‘clerk’ job in 1919 and this year?
2f) What are some other differences between this graph and the 1919 graph? Slide6
3a: What is this data display showing?
3b: What can you tell me about x axis? What can you tell me about the y axis?
3c: How many people were surveyed altogether?
3d: How many men were survey? How many women were surveyed?
3e: What can you tell me about the ‘teacher’ category?
3f: What can you tell me about the ‘home duties’ when compared to the previous 2 graphs?
3g: How many more jobs were present when compared to the first survey? Slide7
So what?
4a:
Compare the 3 data displays. Write down 3-6 things you noticed? What has changed?
4b:
Evaluate: Which data display (graph) did you think was the best and why?
4c:
Where to now? How would you go about getting current data? See your teacher and discuss…
