The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>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:
<u>Where:</u>
- x is the observed data or sample mean.
- u is the mean.
is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.
