A question that doesn't have a clear answer that needs further investigating is called a statistical question. To answer a statistical question, we first collect the necessary data. Then we can use the data to understand trends and make predictions, which we can use to provide an approximate answer to the question.

For example, this question is not a statistical question as there is only one obvious answer.

*How many siblings do I have?*

The question below is an example of a statistical question because there's no obvious answer.

*How many siblings does a typical person have?*

We would need to collect information about the siblings of several people, and use this to approximate the answer.

- Analyse the data you collected. Decide how the information gathered will be grouped, organise the data, and count the data in each group.
- Present the data. Create a line plot, bar graph, picture graph, etc. to represent your findings.
- Interpret the results. Write 3 statements that can be concluded from the information that you gathered on your topic.
