Question

When the mean is the best measure of central tendency?

• A. continuous and symmetrical data
• B. discontinuous and symmetrical data
• C. skewed data only
• D. continuous data only

Answer 1

Answer: (D)

continuous data only

$\Rightarrow$ The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.

$\Rightarrow$ However, it all depends on what you are trying to show from your data.

$\Rightarrow$ The mean is equal to the sum of all the values in the data set divided by the number of values in the data set.

$\overline{x}=\frac{x_1+x_2+x_3+...x_n}{n}$
