Campbellsville High School students recently used their hair to help them study standard deviation.
AP biology students in Lauren Bennett’s class have learned how to calculate standard deviation, which is a mathematical calculation that refers to the reliability of data.
To help them practice the calculation, Bennett asked students to measure the length of their hair and then use the measurements to calculate standard deviation.
Male students worked together, and female students formed a group.
