Learning Outcomes • Understand the importance of precision and accuracy in data collection.
Topic Scientific methods Instructions
Part 1 Using OHS examples describe the differences between;
precision
accuracy
variability
reliability
and validity/. (word count 1000 max)
Part 2 The scientific method is a logical and rational way of investigation that helps us to organise our thoughts and procedures and generally we can identify 7 specific steps in this process, these are:
1. Observation
2. Asking a critical question
3. Developing a hypothesis
4. Making a prediction that can be tested
5. Performing experiments to test the prediction
6. Data collecting and analysis
7. Making a logical conclusion based on experimental results
