Statistics

As part of our learning we have been working on statistical investigations. To do this we conducted a survey after first deciding what we needed to find out. We are now working on presenting and decoding the information we gathered into.

This week we have been working on creating pie graphs. To do this we had to convert our tally marks into percentages of the pie graph. We had to make sure we used a ruler.

 

 

Next we use a protractor to measure the areas of the pie graph.

 

 

Then we used a ruler to go from the centre of the graph to the outside, making sure we divide our pie graph correctly.
