This week, we will continue learning about statistics and how to organise data. We will be looking at interpreting different data and also what we could do if we were working with larger numbers. Have a great week!
- Today, we will be going back to pictograms. But now we will be finding out how to draw a pictogram for bigger numbers. Do you remember last week, each icon had the value of 1. If you spot the key to the side, it shows you that each piece of fruit represents 1. Look at the image below and I will explain the next step.
Here, each piece of fruit represents 1. So there are 7 pears, 1 watermelon, 1 orange, 1 apple and 1 banana.
- However, this can be changed if I was taking data from a larger selection. For example, I did a study across the whole school to find out which was the most popular piece of fruit. My results were:
- 35 pear, 20 orange, 15 banana, 5 apples, 50 watermelon
- These numbers are huge and it would take me a really long time to draw out 50 watermelons!
- So, we can change the 'scale' of each icon. Instead of each icon having the value of 1, it could have the value of 2, 5 or 10.
- So my pictogram would look like the following
- If you notice, my key has changed and my fruit now represents the 5. So, each icon that you see represents 5!
- You could change the key to whichever number is most suitable. It could be 1, 2, 5 or 10 so keep your eyes peeled!
- Have a go at as many activities on the document below as possible.
- There is a challenge sheet below it.
