Did you know...
…that in a normal distribution, about 68% of all values fall within one standard deviation of the mean?
This means that, when it comes to psychological traits like intelligence or personality, most people cluster around the “average.” Values further from the mean become increasingly rare: 95% fall within two standard deviations, and nearly 99.7% within three. These statistical principles are essential in psychological research and test interpretation.
On our Christmas card, this distribution takes festive shape — because sometimes, significance isn’t just found in data, but also in the warmest holiday wishes.
