Let’s graph it

What is statistics? What is a survey? What is the Inquiry cycle? How can we collect data? What are the different ways to show data? How do we make conclusions about the data collected? These are the questions Room 8 learnt to answer as they went on their  journey of learning about surveys. 

The students decided to conduct a statistical investigation themselves with people in Room 8 to answer a question they posed. Arion, Darrius, Madisyn, Lennox M, Izak, Kayde, Zoe, David and Lenox K conducted a statistical investigation to answer a question posed by Mrs Loughin.

The Inquiry Cycle

First, Room 8 learned that the Inquiry cycle is often used when doing a survey. It is composed of 5 steps.

  1. Think of a question

  2. Plan your survey

  3. Collect the data

  4. Draw some graphs and tables

  5. Make some conclusions. 

Room 8 learned about each step in detail. All the students learned the difference between categorical data and number data. Categorical data is data that can be put into groups with names (Example: Which ice cream flavour is most popular with Room 8 students?). On the opposite, number data is data that is put into groups that have number names (Example: I wonder how many pets the students in my class have?)

Once Room 8 knew this major difference they chose their own question. The nine students named above had to answer the question “How many pets do the people in Room 8 have?”

During the Inquiry cycle, the students had to make a poster to show the whole process. 

Madi I learned about the Inquiry cycle. I now know the five steps to follow to do a survey. My next step is to do a survey in my family. I collected number data so next time I will collect categorical data.

Kayde Ilearned the difference between categorical data and number data. Data is the information that you collect for your survey. I will teach that to my brothers.

Next, the students had to plan their survey

  1. What data do you need to collect? Categorical data or number data
  2. How will you collect the data? Room 8 learned about the tally chart and frequency table 
  3. Who will you ask? 28 students, Mrs Loughin and Jackie 
  4. How will you show what you found out? Pictograph, bar chart, strip graph, pie chart and dot plot. 

Then the data was collected. Everybody was asked to be involved with the data collection including Mrs Loughin and Jackie. It was great to see the enthusiasm of all students while gathering the data. There were lots of discussions taking place. 

Sophie I learned that a tally chart can be used to make a frequency table. You need to add a column that gives the total number of tallies in each row. At the end I had to make sure that I had the right total which is 30. There are 28 students in our class plus Mrs Loughin and Jackie, I know how to do tallies now and can use them for lots of things.

Next, Room 8 started to draw graphs and tables to show the data collected. The class had previously worked extensively on what dot plot, pie chart, striph graph, bar chart and pictograph look like. 

It was amazing to see that all students wanted to draw these 5 different ways to show data. 

Jasmine This term, I learned how to draw a dot plot, pie chart, strip graph, bar chart and pictograph. From the data displays, I could see that in Room 8, the students' favourite animal is the dog before horse and cat. They had the choice between 9 animals. I will show my poster to my family and tell them about the Inquiry cycle. It was fun and now I can do another survey by myself.

Finally, Room 8 had to discuss and make some statements analysing the data and making conclusions. They used sentence starters to help them through the process.

As a class, we shared our findings about Room 8 which was fun. We learned a lot about ourselves as a class. It gave us opportunities to discuss important key topics. The surveys results provided a snapshot of the attitudes and behaviours - including thoughts, opinions, and comments - about Room 8. 

Malia My question was: Which country would people in Room 8 like to visit during the holiday? They had a choice between France, Fiji, Cook island, Thailand, China and Hungary. France got the most votes. I will do new surveys with my friends.

Jack My question was: What would people in Room 8 prefer to be? They had the choice between rich, famous, happy or healthy. 13 people chose rich, 12 chose healthy, 3 chose famous and 2 chose happy. We had some interesting discussions in the class about these findings. Voltaire, a French writer and philosopher said that ‘There can be no happiness without good health’ I will ask my family what they would choose.
