The Probable Error of a Mean

Any experiment may he regarded as forming an individual of a “population” of experiments which might he performed under the same conditions. A series of experi­ ments is a sample drawn from this population. Now any series of experiments is only of value in so far as it enables us to form a judgment as to the statistical constants of the population to which the experiments belong. In a greater n...

On Student’s 1908 Article “The Probable Error of a Mean”

This month marks the 100th anniversary of the appearance of William Sealey Gosset’s celebrated article, “The Probable Error of a Mean” (Student 1908a).

This review celebrates the ce...
