What statistical literacy helps with
Launch library · evergreen read
Statistical literacy is the ability to understand and critically interpret numbers presented in public claims, including recognising the difference between a percentage change and a percentage point change, and understanding how sample size can affect how much confidence a figure deserves, a reminder that details matter enormously, which helps explain why it endures.
This skill helps readers notice when a statistic is being presented in a misleading way, such as citing an alarming relative increase from an extremely small base, or comparing figures that were not actually measured on the same basis, which is not always immediately apparent, however routine it may otherwise seem.
Because numbers often carry an appearance of objectivity that plain claims do not, a reasonable level of statistical literacy is an important defence against being persuaded by a figure that sounds precise but does not actually support the conclusion drawn from it, a point that deserves more attention than it gets.
