Study Notes
Scientific Evidence
- Scientific evidence refers to all the data collected during an experiment
- It answers the question of whether the experiment's findings support the hypothesis
Analyzing Data
- To analyze data, identify what it tells you about your question
- Compare the data to your hypothesis to see if it agrees
- Ask yourself what you expect to see if the data agrees with the hypothesis
Does the Data Fit?
- Look for patterns in the data that support the hypothesis
- Check if the data matches your expected outcome
- Replicating results is important to ensure accurate data
- Inconsistent results may indicate an error in the experiment
Interpreting Data
- Interpreting data means explaining what it says about the question
- Most interpretation happens when checking if the data fits
- Write a clear and concise summary of the findings
- Use visual aids like diagrams or charts to illustrate the results
