MATHS

We have started learning about 'Statistics'.

We started by collecting some data. We had to think of a question to ask our classmates, something we wanted to find out. We had to give them choices for their answers and we had to have an 'other' section incase they didn't like the available choices.

We recorded our data with tally charts. Tally charts make counting easy, because you skip count in fives.

Jack is in year 3. He wanted to know what kind of movies we all liked best and he gave us 5 choices. He then put his data into a 'chart maker' at mathswarehouse.com .

Here is his finished graph, it is a bar graph:


What questions can be answered from the information provided on the graph?

Which movie type collected the most votes? (LW)
Which movie type is the least liked? (VS)
Which movie type is the second favourite? (SW)
Which movie type is the second least liked? (NL)
Which movie type did six people in our class like? (FM)
How many people in total were surveyed? (JW)
How many people liked horror movies? (JA)
Did we all like the choices provided? (JH)
How many more people liked horror movies than action movies? (TM)
How many people didn't choose horror as their favourite movie? (JG)

We started with the easy questions first and then we found out there were so many more questions we could answer. We used many maths strategies to answer the questions and our most favourite way to solve maths problems is by making 'tidy ty' numbers.

Lydia is another year 3 student who visits us for maths. Here is her finished graph, it is a pie graph:


What questions can be answered from this graph and what are the answers? Leave your comments!
