EXAMPLES

Some Normal distribution examples. The first is an application of IQ scores as used by NVC's learning specialist and the second is how normally distributed temperatures are changing due to global warming. Note how the change in the mean shifts the distribution left/right while the change in standard deviation changes the shape/width of the bell.
