Understanding IQ test scores


what iq score is considered genius

Genius IQ Scores follow what is known as the Bell Curve. To understand what the score on an IQ test means, there are a few key terms that you should know:

Bell Curve: when IQ test scores are plotted on a graph, they typically follow a bell-shaped curve. The peak of the “bell” occurs where the majority of the scores lie. The bell then slopes down to each side – one side representing scores that are lower than the average, the other side representing scores that are above the average. An example of a bell curve can be seen in the image above.

Mean: The average score. The average is calculated by adding all of the scores together, then dividing by the total number of score.

Standard Deviation: A measure of variability in a population. A low standard deviation means that most of the data points tend to be very spread out from the average. In IQ testing, the standard deviation is plus or minus 15.
