Q: Which equation would you use to calculate the mean value of a set of measurements collected during a lab experiment?

$$ \text{Mean} = \frac{\sum_{i=1}^{n} x_i}{n} $$

Q: A researcher measures the heart rate of subjects before and after exercise. Which formula should be used to calculate the percentage increase in heart rate?

$$ \text{Percentage Increase} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100 $$
