4 These cards represent two different types of data.
The height of a person The weight of a dog The number of students in a class The result of rolling a dice Time taken to run 5K The temperature The number of apples in an orchard The pressure exerted by an elephant The circumference of a circle Don’t mention discrete/continuous straight away Discuss students ideas The amount of money in a savings account Shoe size The number of viewers of a TV show These cards represent two different types of data. In pairs put these cards into two groups.

5 Discrete data can only take certain values.
The height of a person The weight of a dog The number of students in a class The result of rolling a dice Time taken to run 5K The temperature The number of apples in an orchard The pressure exerted by an elephant The circumference of a circle Don’t mention discrete/continuous straight away Discuss students ideas The amount of money in a savings account Shoe size The number of viewers of a TV show Discrete data can only take certain values. Continuous data can take any value (within a range). Which data is discrete? Which data is continuous?

9 Decide which of the following descriptions you would draw a time series graph for.
The annual average temperature in the UK from 2008 to 2018. The number of sweets in 5000 bags produced by Haribo The quarterly sales profit for a clothes shop for the year 2018 The heights of children in particular school. The daily food consumption of a family over a week The birth rate in Scotland from 1900 to 2000.

11 Title: Time Series Graphs
A time series graph can show trends in the data as well as each individual values of the data. In your books: Ben’s quarterly gas bills over a period of two years are shown in the table Plot the data on a graph and comment on any pattern in the data.
