To compare the athletes we need to convert there results into z-scores. The z-score z-score measures the distance of the value from the. A positive z-score indicates the value is above the mean, negative z-score indicates the value is below the mean. A small z-score indicates the value is close to the mean when compared to the rest of the data values. A large z-score indicates the value is far from the mean when compared to the rest of the data values. A random phenomena/experiment is an experiment where we know the possible outcomes, but we do not know what the actual outcome is until after we perform the experiment.
