Elaina records each person's pulse before and after listening to the music. What can you infer is missing from Elaina's scientific investigation? A testable hypothesis naming independent and dependent variables An experiment that takes initial and final measurements Controlled variables with only one varied independent variable Experimental data that can be recorded and analyzed
