What 4 concepts are covered in the Z Score Lookup Calculator?
- distribution
- value range for a variable
- probability
- the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes - z score
- the number of standard deviations from the mean a data point is. Also known as a standard score
