Description
A sample is one or more parts taken from a system and intended to provide information on the system, often to serve as a basis for evaluation of the system (diagnosis) or for a decision on intervention (therapy, production process). Compare: Primary sample.

- An experimental sample is the object of an assay. A sample of a defined sample type subjected to a specific sample preparation (see MitoPedia: Sample preparations) may be e.g. a mitochondrial preparation obtained from an organ, cells suspended from a cell culture dish, a tissue biopsy, an organ, an individual organism, or a group of organisms (e.g. a number of nematodes studied collectively in an experimental chamber).
- EXAMPLE: A blood sample or a biopsy taken from an individual organism. For these examples, the sample size, N, corresponds to the number of organisms in a study group (arm). A sample may be processed and split into a number of subsamples, n (smaller volumes of serum taken from a larger volume of serum), for replicate measurements on the same sample.
