The standard deviation of the population is 2.16. This is calculated by taking the difference of each score from the mean, squaring each difference, summing them, dividing by the size of the population, and then taking the square root of the resulting quotient. In this case, the mean score is 7, the sum of the squared differences is 16, and the population size is 6, resulting in an answer of 2.16.
