Statistics is often regarded as being a means by which observations are expressed numerically in order to investigate causal relations or associations. Things that can be counted, added, divided and sub-divided, analysed, compared, scored as a quantitative measure of assessment. Thus, any fact to be called statistics must be numerically expressed, and should be placed in relation to each other. Qualitative data cannot be included in statistics unless they are quantified by assigning some figures for assessment. However, not all numbers are continuous and measurable. For example, the fact that marks of a student are 50 tells nothing unless it is comparable. Thus, for figures to be included in statistics, they must be aggregate of facts and not individual figures.
