Question

The mean $\overline{x}$ of the data is given by:

• A. ^ΣF_ix_i ⁄_ΣFi
• B. ^ΣF_i ⁄_Xi
• C. ^ΣX_i ⁄_Fi
• D. ^ΣF_ix_i ⁄_ΣX.F

Answer 1

The correct option is A

^ΣF_ix_i ⁄_ΣFi

The mean of the data is the sum of the values of all the observations divided by the total number of observations. It is used to derive the central tendency of the data in a question. It is determined by adding all the data points in a population and then dividing the total by the number of points.
