It is a symmetrical arrangement of a data set in which most values cluster in the mean and the rest taper off symmetrically towards either extreme. Numerous genetic and environmental factors influence the trait. Central Limit TheoremIn that case, a bar code graph may be a better choice. The graphs above show the dependency of cell lines on the gene FOXA1; those to the left of the minus-1 reference line need the gene to survive. Those cell lines are difficult to see on the bell curve, but stand out on the bar code.The IQ bell curve helps categorize where people fall along the scale of intelligence and does so in a neatly compartmentalized way.
