To gather good data, Year 8 students can use a few simple methods:

1. Surveys:

   • Create questionnaires with questions that have set answers.
   • Try to get at least 30 people to answer, so the results are reliable.

2. Experiments:

   • Carry out experiments where you only change one thing at a time.
   • Keep track of your data carefully. It’s best to do each experiment three times to make sure the results are trustworthy.

3. Observational Studies:

   • Collect information by watching things happen without getting involved.
   • Use tally charts for numbers and write down descriptions for what you see.

These methods will help students gather useful and accurate data for their analysis.
