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.
Bell curve may refer to: 1  A Gaussian function, a specific kind of function whose graph is a bell-shaped curve. 2  Normal (Gaussian) distribution, whose density function is a Gaussian function.ell curve may refer to: 1  A Gaussian function, a specific kind of function whose graph is a bell-shaped curve. 2  Normal (Gaussian) distribution, whose density function is a Gaussian function.
The only two numbers that we care about in it are the mean and standard deviation. The bell curve for a given set of data has center located at the mean. This is where the highest point of the curve or âtop of the bellâ is located. A data setâs standard deviation determines how spread out our bell curve is.The larger the standard deviation, the more spread out the curve.he only two numbers that we care about in it are the mean and standard deviation.
