I am conducting a test to determine if there is a connection between how long you run and how fast your heart beats. I will perform an experiment where a person will run for 1 minute, and I will check their heart rate. Then, they will run for 2 minutes, and I will check their heart rate again. I will continue this up to 6 minutes and analyze if there is a connection.
What do you think my hypothesis should be? What are my variables?
Independent variable:
Dependent variable:
Answer (3)
Hypothesis: when a person runs, their heart beat increases with the amount of time they run. Your independent variable is checking heartbeat because that never changes. Your dependent variable is the about of time running because this gradually does change Also remember to test each time interval at least three times :)
Your **hypothesis **could be: 'The longer the duration of running, the higher the heart rate.' In this experiment, the independent variable is the duration of the run and the dependent variable is the heart rate.
In your experiment to check if there is a relationship between how long one runs and their heart rate, the hypothesis could be: 'The longer the duration of physical activity (in this case, running), the higher the heart rate.' The identified variables would be: the **independent **variable, which is the duration of the run (measured in minutes), and the **dependent **variable, which is the heart rate (measured in beats per minute). These variables allow you to monitor and track any changes in heart rate relative to the duration of running.

Your hypothesis could be: 'If a person runs for a longer time, then their heart rate will increase.' The independent variable is the duration of the run and the dependent variable is the heart rate. Keeping the person's resting condition constant is important for accurate results.
