# Data Detectives

### “How many of each flavour are in a bag?” Wondered Petra Hutton as Room 8 students stared, mouths watering, at a bag of one of New Zealand’s all-time favourite lollies - Fruit Bursts.

Data Detective Process Statistical Investigations

This wonder about a packet of Fruit Bursts provided the basis for Room 8’s introduction to the statistical investigation process.

As a class we put on our data detective hats and using the statistical investigation process began solving the question/problem.

After discussing as a class the question/ problem and determining how we were going to answer/ solve it we split into small groups.

In our groups, we planned how to sort the data or in this instance sort the Fruit Bursts. All groups decided the simplest way to do this was to group the Fruit Bursts based on the characteristic of colour/ flavour. Some groups discovered that by ordering the groups of Fruit Bursts from largest to smallest or vice versa they were able to more clearly analysis the data.

Lucas Hill commented that this makes it clearer in my head.

After analysing the data we discussed how to present it in a visual form. All groups decided to configure a bar graph using their sorted data. We worked together to make sure the bar graph included all components such as an appropriate title and axis labels.

Finally, we came to the last step of the statistical investigation process -  drawing conclusions.

Carly Arnold found that in her groups' packet of Fruit Burst strawberry Fruit Bursts are the most popular as there are 8 of them.

Layne discovered lemon and lime had the least amount with 3 in his groups' packet.

Then we presented our findings to the class in our groups by summarising our conclusions and compared the different findings from each group. We discovered that each individual packet or Fruit Bursts was unique. They all had a different number of each colour/ flavour in them.  As a class, we provided each group with feedback and next steps in relation to their presentation of their learning. Some of these next steps included using different colours for each bar to make the graph easier to read visually, and checking that all axis were labelled correctly.

Our next step as a class is to now pose another question to investigate as individuals following the same statistical investigation process.
