Today we started learning about statistics.

First, we did a pre-test, which was to see what we already know.

It didn't matter if we didn't know anything, we just had to try our best.

Next, we went outside.

OUTSIDE FOR MATHS? WHAT! I KNOW!

We tried our making each of the types of graphs we are going to learn about, but with our bodies and using chalk to write on the concrete.

We tried our making each of the types of graphs we are going to learn about, but with our bodies and using chalk to write on the concrete.

We started by choosing our favourite take-away and sitting behind it. This created a pictogram.

On a pictogram the frequency is represented by pictures. In our picture, it is represented by us!

Next, we made a dot plot.

We used our bodies to represent the 'dots' on a dot plot. The question we used for this was which month is your birthday in.

A normal dot plot looks like this -

Next, we made a bar graph.

We chose our favourite colours for our bar graph. See the lines around where we are sitting? That is what is different between a dot plot/pictogram is that bar graph uses bars (like oblongs).Like this -

Next, we created a line graph.

A line graph shows where you sit compared to TWO different things, for example, your height and your weight, at the same time. Those are the variables we used.

We put ourselves into height order and lined up on the y axis (measuring height) and then moved up to how much we weighed (the x axis). This created a crooked line.

Then we moved off our line to show where we were standing, and what it looked like without our bodies in the way.

The next graph we made was a strip graph. For this, we used the topic of our favourite fizzy drink. Like the bar graph, strip graphs have a box instead of dots or pictures. So we stood in our box to show which one we voted for that was our favourite.

This is what a strip graph looks like, without the people in it.

The next graph we made was a pie chart. Instead of doing a full circle, we made a half circle just so we could actually take a photo of it.

For this, we used the topic of our favourite sports to play.

The pieces of the pie that have more people are bigger than those who only have 1 or 2 people in them.

We had different categories (from R - L) like other, soccer, american football, netball, rugby, and softball.

This is what a full circle pie chart looks like.

The last one we made was a table.

A table looks like this -

We made ours based on how many siblings we have (the numbers below the yellow line). We stood at the back of our table to show the number of people who had that many siblings. For example, 3 people have 2 siblings, 2 people have 3 siblings, 2 people have 4 siblings, 0 people have 5 siblings, 4 people have 6 siblings, 1 person has 8 siblings and 2 people have 10+ siblings.

Hopefully because we did a physical activity and used our bodies to help create these graphs, it will stick in our heads a little more than if we had just been shown a picture one time.

Onwards and upwards!
