Since 1.5 can also be written as 3/2, and inverse is 2/3
The absolute value equation for the scores within one standard deviation of the mean is:
|x - 20.9| = 5.3.
The minimum score that is within one standard deviation of the mean is of 15.6.
<h3>What is the absolute value function?</h3>
The absolute value function is defined by:
It measures the distance of a point x to the origin of x = 0.
One standard deviation is of 5.3, while the mean is of 20.9, hence the absolute value equation for the scores within one standard deviation of the mean is:
|x - 20.9| = 5.3.
Which means that the minimum score is:
x - 20.9 = -5.3
x = 15.6.
