Statistics – Bar graphs
I am learning to analyse results on a bar graph.
I know I can do it when I have answered questions from a bar graph.
This week we will be looking at other types of graphs including bar graphs and pictographs.
Today’s focus is on bar graphs. These types of graphs are used to record data for questions that could have many answers.
Unlike a tally graph which records across the page, a bar graph will typically record up the page starting at the bottom.
A bar graph needs:
- A title at the top (what the question is)
- Labels along the bottom (the answers)
- Numbers up the sides and columns (how many of each answer).
Watch the following video to learn more about bar graphs:
Look at the following bar graph which has asked the question ‘what is your favourite flavour of ice cream?’
Copy the graph by drawing it into your scrapbook.
Write 3 sentences about what information the bar graph tells us.
An example of a sentence may be ‘Rainbow flavoured ice cream is the most popular choice with 8 people saying it was their favourite.’
When writing your sentences remember to begin each sentence with a capital letter and end with punctuation.
