are nominal and ordinal scales.
Categorical Data
It is defined as the difference between the highest value and the lowest value of the distribution.
Range
A measure that divides a distribution into four equal parts.
Quartile
The number of data belonging to a class interval is _______.
Class Frequency
The square root of the variance is ________.
Standard Deviation
a more reliable measure of variability
Interquartile Range
measures how many standard deviations an observation is above or below the mean and allows us to compare the results to different normal
distributions.
