Question

The mean of discrete observations $y_1,y_2,\dots \dots y_n$ is given by

• A. $\frac{{\sum }_{i=1}^n{y}_i}{m}$
• B. $\frac{{\sum }_{i=1}^n{y}_i}{{\sum }_{i=1}^{n}i}$
• C. $\frac{{\sum }_{i=1}^n{y}_i{f}_i}{n}$
• D. $\frac{{\sum }_{i=1}^n{y}_i{f}_i}{{\sum }_{i=1}^n{f}_i}$

Answer 1

The correct option is A

$\frac{{\sum }_{i=1}^n{y}_i}{m}$

Mean of discrete observations $y_1,\dots \dots y_n$ is given by $\frac{{\sum }_{i=1}^n{y}_i}{n}$
