It is not a good method for estimating small or large percentage points (for example, the height at which 99 per cent of specimens explode) unless normality of the distribution is assured. In fact, no method which uses the normal distribution can be relied on to estimate extreme percentage points because such estimates depend critically on the assumption of normality. In most experimental research,...

Page A-8 - When there is some logical basis for the selection of a particular equation, the equation and the corresponding curve may provide a definite logical measurement of the nature of the relationship., When no such logical basis can be developed, a curve fitted by a definite equation yields only an empirical statement of the relationship and may fail to show the true relation. In such cases a curve fitted freehand by graphic methods, and conforming to logical limitations on its shape, may be even more...
