# Bar Graphs 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 do bar graphs show?

Bar graphs show grouped numerical data using bars, making it easy to compare different quantities.

## How do you construct a bar graph?

Draw the axes and label the x-axis with categories (e.g., months) and the y-axis with the measurement scale (e.g., mm of precipitation).

Draw bars extending up to the appropriate value on the y-axis for each category.

## What does a population pyramid display?

A population pyramid displays the age distribution of a population, with the x-axis representing the number of people in specific age groups and the y-axis listing those age groups, often differentiating between genders.

Population pyramids are valuable for analysing population dynamics such as birth rates, death rates and life expectancy, helping us understand the age structure of a population.
