median: 6
mode: 6
variance: 4
the z - score is the number dropdown data value is away from the
options: means, quartiles, standard deviations

Explanation:

The z - score (also called standard score) is defined as the number of standard deviations a data value is away from the mean. The formula for z - score is $z=\frac{x - \mu}{\sigma}$, where $x$ is the data value, $\mu$ is the mean, and $\sigma$ is the standard deviation. So the correct option is the one related to standard deviations.

Answer:

standard deviations
