Question 2 of 10

Answer 1

The better statistics which can be used to compare the given distributions are mean and standard deviation.

What is a z-core?

A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.

In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:

$Z=\frac{x\;-\;u}{\delta}$

Where:

• x is the observed data or sample mean.

• u is the mean.

• $\delta$ is the standard deviation.

In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.
