Note: Medians are reported in this study instead of means (averages) because medians represent the “typical” response and aren’t influenced by extreme values. A median is the value that lies at the middle of a distribution; that is, 50% of the values are above it and 50% are below. Medians for grouped or categorical data are calculated by locating the group that contains the 50th percentile, then interpolating between the lower and upper bounds to estimate the precise value.
