WebOption C: This option is incorrect because we don't need to square the standard deviation σ. If we square the σ it is called variance. The formula is σ² = ( Σ (x-μ)² ) / N. Variance used in population not in the sample. Option D: This option is incorrect because μ is a parameter that represents a measure of the population, not the sample. WebStatistics Formulas. The branch of Statistics deals with the study of the collection, analysis, interpretation, presentation, and organization of data.
