Explaining the importance of measurement in science and the inevitability of uncertainty, this program emphasizes the need for multiple measurements and taking averages. It teaches how to estimate the range of uncertainty in measurements, discusses outliers, and differentiates between accuracy and precision. It also teaches how to manage uncertainty when performing calculations with measurements and shows how to express uncertainty in standard form. The program concludes with a practical exercise—measuring the diameter of the sun and then estimating the uncertainty in the results.
