The lower the pH reading, the more acidic the solution. Readings from 0â7 are considered acidic, and numbers from 7.0â14 are considered basic, or alkaline. Pure water, in the very middle of the (logarithmic) pH scale, has a pH of 7.0, which is considered neutral.

A good example of a bell curve or normal distribution is the roll of two dice. The distribution is centered around the number 7 and the probability decreases as you move away from the center. Here are the % chance of the various outcomes when you roll two dice.2 - 2.78 % 8 - 13.89 %. 3 - 5.56 % 9 â 11.11 %.he important things to note about a normal distribution is the curve is concentrated in the center and decreases on either side. This is significant in that the data has less of a tendency to produce unusually extreme values, called outliers, as compared to other distributions.
