# Glossary¶

experiment
A computational experiment, inheriting from Experiment. Experiments are run at a point in a multi-dimensional parameter space, and should be designed to be repeatable.
experiment combinators
Experiments that wrap-up other, underlying experiments and perform them in some way, perhaps repeating them or summarising or re-writing their results. They allow common experimental patterns to be coded.
experimental configuration
A list of pairs of an experiment and the parameters at which it will be run, created according to an experimental design.
experimental design
The way in which a set of parameters is converted into points at which experiments are run.
experimental parameters
The values used to position an individual experimental run in the “space” of all experiments. Each experiment has its own parameters, which it can use to configure itself and perform set-up (see The lifecycle of an experiment).
experimental results
The collection of values returned by an experimental run.
lab
A computational laboratory co-ordinating the execution of multiple experiments, inheriting from Lab.
An immutable and often persistent store experimental results and metadata, inheriting from LabNotebook.
The set of experimental parameters at which experiments will be run. The parameter space is defined by a Design,
