Definitions:

Upper Quartile

The value below which 75% of the observations in a group of data fall, marking the upper 25% of the data.

Weights

A measure of the heaviness of an object or the importance assigned to elements in a computational operation.

Police Officers

Law enforcement members responsible for maintaining public order, enforcing laws, and preventing, detecting, and investigating criminal activities.

Whiskers

In a box plot, the lines that extend from the quartiles to the furthest data points within a reasonable range, representing the spread of the bulk of the data.
