Math - Data set

A data set in mathematics is a collection of related data points or values, often used in statistics to analyze and interpret information.

• Median - The middle value of a data set.
• Mean - The average of a data set.
• Mode - The most common number in the data set.
• Range - The difference between the largest and smallest number in the data set.

Examples

Median

$\{1,1,3,3,3,\textcolor{#7932ff}{6},7,8,8,9,9\}\\$

Mean

$\frac{\text{Total of all the numbers}}{\text{Count of the numbers}}$ = $\frac{2+2+4+5+8+12}{6} = \frac{33}{6} = \textcolor{#7932ff}{5.5}$

Mode

$\{2,3,3,5,\textcolor{#7932ff}{7},\textcolor{#7932ff}{7},\textcolor{#7932ff}{7},\textcolor{#7932ff}{7},9,13\}$

Range

$\small\text{largest number} - \text{smallest number}$
$\{4,5,6,8,15,17\}\\ 17-4\\ \textcolor{#7932ff}{13}$
