Practice question · Sort into groups
Sort each activity into the planning or analysis phase of an experiment.
Groups: Planning phase · Analysis phase
- Formulating the hypothesis
- Choosing controlled variables
- Propagating uncertainties to the final result
- Calculating the chi-squared statistic
- Plotting residuals
- Designing the data collection table
Hints
- Ask whether the activity happens before or after data exists.
- Choosing what to measure precedes deciding what it means.
Show the answer
Planning phase: Formulating the hypothesis, Choosing controlled variables, Designing the data collection table
Analysis phase: Calculating the chi-squared statistic, Plotting residuals, Propagating uncertainties to the final result
Why
Good experiments require careful planning before and rigorous analysis after data collection.
