References can be made to the distribution of data, the distribution of scores or the dataset distribution.**An arranged dataset.**The organized arrangement of data, normally for representing frequencies (eg, histograms) or individual scores (eg, ranked distribution of scores).**A probability distribution.**Theoretical arrangements of data which provide know probabilities of occurrence. Real results are then compared against the theoretical distribution in order to ascertain the probability of such data under such theoretical distribution. Well known distributions are z-distributions (ie, the normal curve), t-distributions and F-distribution. Probability distributions are used for making inferences from a sample to a population.
