Maximum unambiguous range maximum theoretical range

Interquartile range = range between the first and third quartile.

Cumulative frequency = sum of all frequencies for all values.

Variance = the average of the squared differences from the Mean.

Standard variation = the average of the squared differences from the Mean under a squared root (the same as Variance just under a square root to get rid of the squared unit).

The Range = The distance between two values of which we combine their frequencies to simplify longer datasets.

Quartiles = A division of a dataset into 4 equal parts.

Whisker Plot Box = graphical representation of a dataset’s distribution based on a five values: 

1. Minimum


2. First quartile (Q1)


3. Median


4. Third quartile (Q3)


5. Maximum

The Measures of Dispersion= measures how spread out or scattered data points are around a central value (mean or median
