Save a copy Lesson 2: Global data Year 9 – Data science

Starter activity Tracking the traffic What do the different colours on this visualisation represent? What data is needed to show you this visualisation? How do you think this data is collected? Think/pair/share. 2

Objectives Lesson 2: Global data In this lesson, you will: ● Recognise examples of where large data sets are used in daily life ● Select criteria and use a data set to investigate prediction ● Evaluate findings to support argument in favour or against your prediction 3

Activity 1 Large data sets Advances in technology have made it more feasible to collect, store, and analyse data on a much larger scale. Let’s consider how a company such as Netflix collects data. Watch this video 4

Activity 1 Large data sets What other companies can you think of that might collect large sets of data? How do you think they use this data to help them make decisions? Think/pair/share. 5

Activity 2 Global data: where’s the best place to live? We are going to look at a large data set that compares countries across the world, in order to help us work out the answer to the following question: Where is the best place in the world to live? 6

Activity 2 Best place to live: criteria Most of us like the idea of living somewhere like in this picture, but would it really be the best place to spend the rest of your life? Which of the following are most important to you? ● ● Life expectancy Average income/wealth Health CO 2 emissions Anything else? 7

Activity 2 Best place to live: criteria Pick three to four of the following criteria: ● ● ● Life expectancy Average income/wealth Health CO 2 emissions Average temperature ● ● ● Inequality Unemployment levels Population density Freedom of speech (civil liberties) Crime (murders per 100, 000 people) 8

Activity 2 Proving our theory: Gapminder We will use a data visualisation tool called Gapminder to help us decide where the best place to live is, based on the criteria that you set. gapminder. org/tools Teacher demonstration 9

Activity 2 Proving our theory: Gapminder Use your criteria to investigate your prediction. Document your findings on your worksheet. Use the following websites: gapminder. org/tools berkeleyearth. lbl. gov/country-list (for average temperature only) 10

Plenary Where is the best place in the world? Discuss your findings with the class. Can we agree on where in the world is the best place to live? 11

Summary Next lesson In this lesson, you… Next lesson, you will… Explored examples of where large data sets are used in everyday life Look at the terms correlation and outliers in relation to data trends Selected criteria to determine where the best place in the world is to live and used a data set to investigate your prediction Use the steps of an investigative cycle to help us find answers to a question or problem using data 12
