4 Frequency histogram for the continuous variable x over the range 0 to +10. The mean, since it is derived from a sample, is known as a statistic. The corresponding value for a population, the population mean, is given the symbol μ and this is known as a parameter, another use for the term. A convention in statistics is that Greek letters are used to denote parameters (measures or characteristics of the population) and Roman letters are used for statistics. The mean is known as a ‘measure of central tendency’ (others are the mode, median and midrange) which means that it gives some idea of the centre of the distribution of the values of the variable.

Experimental design terminology Experimental design techniques Compound and set selection High throughput experiments WHAT IS EXPERIMENTAL DESIGN? All experiments are designed insofar as decisions are made concerning the choice of apparatus, reagents, animals, analytical instruments, temperature, solvent, and so on. Such decisions need to be made for any individual experiment, or series of experiments, and will be based on prior experience, reference to the literature, or perhaps the whim of an individual experimentalist.
This calls for a design known as a Graeco-Latin square which is made by superimposing two different Latin squares. There are two possible 3 × 3 Latin squares: A B C A B C B C A C A B C A B B C A The 3 × 3 Graeco-Latin square is made by the superimposition of these two Latin squares with the third blocking variable denoted by Greek letters thus: Aα Bβ Cγ Bγ Cα Aβ Cβ Aγ Bα It can be seen in this design that each treatment occurs only once in each row and column (two of the blocking variables, say time of day and cofactor batch) and only once with each level (α, β, and γ ) of the third blocking variable, the enzyme batch.
