Basic properties of the normal distribution, Section 3.2. He considered that the . in making an observation is the sum of a very large number of very small errors each of which might be . or . at .. He then proved mathematically that, if . is the total error, the population of total errors has a probability density function (defined in Sectio

,The χ2-test for ‘goodness of fit’: test for ‘association’,tter to have some test available to determine quantitatively whether a set of observations really could come from a given (or a hypothetical) distribution. Karl Pearson in 1899 by using properties of the . distribution (see Section 8.6) devised the ‘. test’ for this purpose (there are other tests, b

Fitting lines and curves to data, least squares method,often called ‘scatter’ (e.g. the yield in some chemical reactions is frequently subject to scatter), whereas the other quantity can be determined beforehand exactly (e.g. the.temperature or the duration of a reaction can be determined exactly, but the yield often cannot). The problem then is to find
