In maths, we have been exploring statistics. Please ask the people in your household for their favourite flavour of ice cream, then record their answers in a tally chart (see example below).
TIP: When collecting the information, for every person who votes, a line would be drawn in the correct box. When you get to five lines, the fifth line needs to be crossed through the first four (This makes counting lines at the ends easier!).
Once you have collected the data, record on a bar chart (see below).
A bar chart displays information (data) by using rectangular bars of different heights.
A bar chart has a vertical axis with numbers on it, and a horizontal axis showing values of something that has been investigated.
- First, think about what is going to go on each axis.
- Then, look at your numbers and make sure your vertical axis goes up as high as the biggest number.
- Work out whether the numbers on the vertical axis are going to go up in 2s, 5s or 10s and position the numbers correctly.
- After that, work out how wide each bar needs to be. (It is very important that bars are drawn all the same width).
