Quick wits – Week one

Representing data Think about all the different was you know that data can be represented graphically and make a quick sketch on post-its of each one you think of. Make sure you use a separate post-it for each diagram It doesn’t have to be neat or accurate but it does need to be recognisable. Pick one person to stick their diagrams in a row on the wall and write a label describing the diagram underneath.

What have we created?

Data presentation and analysis This is the list from AQA: frequency tables bar charts pie charts pictograms vertical line charts Two way tables Line graphs for time series data

Commonly known frequency tables (you may know them tally charts) bar charts pie charts pictograms vertical line charts

It is a method of showing data in a simple form. What is a two-way table? It is a method of showing data in a simple form. The reason it’s called a two-way table is because there are two headings. Find the value that matches up with both conditions that you are looking for.

A pet shop sells cats. They are available only in 2 types, ginger or white. The shop has 14 male ginger cats. There are 40 cats altogether, and a quarter of them are white. There are 6 female cats that are white. Draw up a table showing the number of each type of cat. What percentage of the cats are white male cats? Suggest a possible reason why the shop has more cats of one type than another.

What sort of table did you draw to organise this data? CATS Ginger White Total Male 14 4 18 Female 16 6 22 30 10 40

Frequency diagrams (past paper question) Normally other topics are included in the question.
