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
