Usually, we are interested in the standard deviation of a population. Her hair is black with hints of red, the color of seaweed spread over rocks. The spread of a distribution tells you the range of your data. If your spread is small, then your data covers a short range. If your spread is large, then the data covers a larger range. For our donuts, a small range would mean that people cluster together with their choices being very close to each other. To calculate the range, you just subtract the … First, if the data values seem to pile up into a single "mound", we say the Specific numerical values are not required. B. ★★★ Correct answer to the question: Which statement correctly compares the spreads of the distributions? Wave 1 has taller crests than Wave 2. Spread. However, as we are often presented with data from a sample only, we can estimate the population standard deviation from a sample standard deviation. 2) The mean exceeds the median by 2.
