Block Sampling is a judgment sampling method in which accounts or items are chosen in a sequential order. After the initial item in the block is selected, the balance of the block is automatically chosen.
Cluster sampling is a method of selecting a sample by dividing the population into clusters (groups) and then taking a random sample from each cluster. This technique is commonly used in auditing.
Factor Analysis is a mathematical procedure used to reduce a large amount of data into a structure that can be more easily studied. It summarizes information contained in multiple variables into a smaller number of interrelated factors.
Estimating unknown quantities that lie between two of a series of known values. Interpolation is a statistical method often used in various fields including finance, science, and engineering.
Nonparametric statistics refers to statistical methods that do not assume a specific population distribution and are based on distribution-free procedures. These methods are useful when data do not meet the assumptions required for parametric tests.
Systematic sampling is a probability sampling method where researchers select every nth observation from a larger population, following an initial randomly chosen starting point.
Variables sampling is a statistical method used primarily in auditing to predict the value of a given variable within a population. It is often used to estimate the total amount or the arithmetic mean of a characteristic within a sample.
