| distribution volume | The volume throughout which an added tracer substance appears to have been evenly distributed, calculated by dividing the amount of tracer added by its concentration after equilibration. (05 Mar 2000) |
| t distribution | The distribution of the quotient of independent random variables, the numerator of which is a standardised normal variate and the denominator the positive square root of the quotient of a chi-square distributed variate and its number of degrees of freedom. (05 Mar 2000) |
| tissue distribution | Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. (12 Dec 1998) |

| f distribution | The distribution of the ratio of two independent quantities each of which is distributed like a variance in normally distributed samples. So named in honor of the English statistician and geneticist R.A. Fisher. (05 Mar 2000) |
| frequency distribution | A statistical description of raw data in terms of the number or frequency of items characterised by each of a series or range of values of a continuous variable. (05 Mar 2000) |
| lognormal distribution | If a variable y is such that x = log y, it is said to have a lognormal distribution; this is a skew distribution. (05 Mar 2000) |
| normal distribution |
A term synonymous with the standard normal distribution. The normal distribution (a bell-shaped curve) represents a theoretical frequency distribution of measurements. In a normal distribution, scores are concentrated near the mean and decrease in frequency as the distance from the mean increases.

| normal distribution |
A frequency distribution that predicts the probability that a variable will take a certain value; the distribution is symmetrical about the mean value. Based on statistical theory, the normal distribution underlies much statistical analysis

| normal distribution |
A variable follows a normal distribution if it is continuous and if its frequency graph follows the characteristic, symmetrical, bell-shaped form in which all the values of mean, median and mode co-incide (see graph on the left).

| normal distribution |
Statistical distribution in which data are represented by a bell-shaped curve. The distinct shape and position of the curve are determined by the mean and the standard deviation.
