Question

Arithmetic mean of a given frequency table depends on _______.

• A. frequencies of the scores only
• B. the scores only
• C. both scores and its frequencies
• D. None of the above

Answer 1

The correct option is C both scores and its frequencies

Arithmetic mean = $\frac{\sum f_i{x}_i}{\sum f_i}$ , where $x_i$ is the scores and $f_i$ is the frequency of the corresponding score $x_i$
$\Rightarrow$ mean depends on both scores($x_i$) and its frequencies($f_i$)
