## Key ideas

How the results of an investigation are interpreted depends on a number of factors. These can include:

- the number of variables to be considered
- the sophistication of the procedure (that is, appropriateness of the approach and method chosen)
- the quality of the data collected
- the theoretical perspective of the scientist interpreting the data.

## Teacher reflection

- How can there be more than one explanation for the results of an investigation? Does at least one of the explanations have to be wrong?
- Would the ‘perfect investigation’ have only one explanation? Why or why not?
- If there is more than one explanation for the results of an investigation, should further investigations be carried out? Why or why not?
