# Graph Types and Uses Flashcards

1️⃣ Familiarise yourself with the flashcards:

• Look through all the flashcards to see what’s on both sides.
• Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

• Look at the question or prompt on each card and try to remember the answer before flipping it over.
• Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

• Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
• Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

## What is quantitative data?

Quantitative data is a type of data represented by numerical values. It is used to quantify the amount of something and allows for mathematical calculations and statistical analysis.

## What is the difference between discrete and continuous data?

Discrete data has specific, limited values (e.g., number of students).

Continuous data can represent any value within a range (e.g., temperature).

## What are line graphs used for?

Line graphs are used to show change over time or space, typically visualising trends in data over time with a continuous line across two axes.

## When should you use a pie chart?

Pie charts are ideal for showing proportions and how a total is divided among different categories.

## What is a scatter graph?

A scatter graph plots data points without connecting them. It is used to visualise the relationship between two variables, often with a line of best fit.

## What are the strengths of histograms?

Histograms are excellent for showing the distribution of continuous data. They are easy to understand and interpret, dividing data into bars called ‘bins’ of equal width.
