what is the definition of normal dispersion?
11513
Definition of normal dispersion. : dispersion (as of light by an optical grating) in which the separation of components in any one spectrum increases continuously and almost uniformly with the wavelength, the separation being a monotonic function of the dispersion variable.

The normality of a solution is the gram equivalent weight of a solute per liter of solution. ... For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given chemical species (ion, molecule, etc.).

Absolute & relative dispersion are two different ways to measure the spread of a data set. ... The easiest way to differentiate relative dispersion/absolute dispersion is to check whether your statistic involves units. Absolute measures always have units, while relative measures do not.

Where molarity describes the moles of a complete substance per liter of solution, normality describes only the moles of reactive species per liter of solution. Normality is always a multiple of molarity.

The standard normal (or Z-distribution), is the most common normal distribution, with a mean of 0 and standard deviation of 1. ... The t-distribution is typically used to study the mean of a population, rather than to study the individuals within a population.

Standard Deviation is a statistical term used to measure the amount of variability or dispersion around an average. Technically it is a measure of volatility. Dispersion is the difference between the actual and the average value. The larger this dispersion or variability is, the higher is the standard deviation.

Dispersion. ... Interquartile Range (IQR) It is the better measure of dispersion than the Range. It uses the terms Q1, Q2, Q3, Q4 to denote each quarter of the data set. Q1 lies at the 25th percentile, Q2 lies at the 50th percentile or median, Q3 lies at the 75th percentile, and Q4 lies at the 100th percentile.

A normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme. ... The precise shape can vary according to the distribution of the population but the peak is always in the middle and the curve is always symmetrical.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. ... The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance.

A normal distribution is an arrangement of data that is symmetrical and forms a bell-shaped pattern where the mean, median and/or mode falls in the centre at the highest peak.

The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. ... Examine the table and note that a "Z" score of 0.0 lists a probability of 0.50 or 50%, and a "Z" score of 1, meaning one standard deviation above the mean, lists a probability of 0.8413 or 84%.

Volume of distribution (Vd), represents the apparent volume into which the drug is distributed to provide the same concentration as it currently is in blood plasma. It is calculated by the amount of the drug in the body divided by the plasma concentration [19].

The standard normal distribution, represented by the letter Z, is the normal distribution having a mean of 0 and a standard deviation of 1.

Molarity ( ) is defined as the number of moles of solute per liter of solution. Molality ( ) is defined as the number of moles of solute per kilogram of solvent. Normality ( ) is defined as the number of equivalents per liter of solution.

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. The difference in the concentration of a substance between two areas is called the concentration gradient .

The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z. It does this for positive values of z only (i.e., z-values on the right-hand side of the mean).

Description. Standard deviation is the statistical measure of market volatility, measuring how widely prices are dispersed from the average price. If prices trade in a narrow trading range, the standard deviation will return a low value that indicates low volatility.
