Statistics

Yesterday we did a little experiment. We shut our eyes and chose a cube from the tray. All 30 of us chose a cube. We could have chosen any one of 10 different colours.
This is the pile of cubes we randomly chose

We decided we could see our results more clearly if we grouped them like this!

We pulled out 30 cubes 3 different times.  Every time we did it we got a different result.  We grouped our results into bar graphs so we could see more clearly how many of each colour we chose.

We saw some things that were similar.  Lots of things that were different.

Jamie was having a closer look at the bar graphs so he could make comparisons.
