You know statistics is all about collecting information (data) and presenting it in a graph to show that information more clearly. Statistics data can tell us so much about a topic and can be used to plan for all sorts of things.
Room 6 quite often has shared lunches and ice cream would be a popular food to have, especially in the summer. Imagine if Mrs Dobbie went to the supermarket to buy the ice cream and didn't know what we liked flavour wise. She would have to guess and if she guessed wrong then there would be a lot of disappointed children and a lot of ice cream left to melt :(
So just in case, we do get ice cream (hint, hint Mrs Dobbie) we collected some data about our favourite ice cream and graphed it. What kind of graph do you think it is?
After we made some statements about what was the most and least popular flavours, just to make it clear for Mrs Dobbie.
We know that for every person who votes we write one tally mark. After 4 tally marks we put a line through the 4 to make 5 tally marks. This makes it easier to count. Imagine having to count 100 tally marks. We would lose count because it would look like this:
llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
Cross-eyed yet?
We also know that to have accurate data people can only vote once. Some of us found that quite hard because we really couldn't make our minds up as to which was the best flavour. Mrs Dobbie especially as she loves all ice cream!
Another important thing we now know is that the number of votes in total should equal the number of people who voted. If these numbers don't match then something is not right and our data will be inaccurate.
Make sure you buy goody goody gumdrops, Mrs Dobbie! That's the most popular flavour. Poor cookies and cream was the least favourite.
