Treatment of the Data Seted in the order in which they were made. With respect to analytical data, the data set is usually the certificate of analysis issued by the laboratory. Table 1 illustrates a data set of Si02 analyses from 20 barite samples (l-kg rock samples).

Estimation of the Errors collected. This therefore raises the question of how “precisely” does the mean value of the sample reflect that of the population. In other words, how large is the uncertainty of the mean value, or what is the magnitude of “the error”?

Skewed distributions Thus, higher grades occur in addition to the average grade tenor, and they extend beyond the range considered as the normal distribution. These irregularly high values or enrichments frequently convert mineralisation into orebodies.

Defining an Exploration Gridations in Exploration, Chap. 10). The definition of the grid for the subsequent geochemical and geophysical exploration represents the first step into exploration statistics. Initially, however, before any statistics are taken into consideration, all the geological information must be fully compiled and evaluated.
