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 in a data set.
• Mean: The average of all values in a data set.
• Mode: The most frequent value in a data set.
• Range: The difference between the largest and smallest values in a data set.

Examples

Median

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

Mean

$\frac{2+2+4+5+8+12}{6} = \frac{33}{6} = \textcolor{#7932ff}{5.5}$

$\frac{\text{Total of all the numbers}}{\text{Count of the numbers}}$

Mode

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

Range

$\{4,5,6,8,15,17\}\\ 17-4\\ \textcolor{#7932ff}{13}$

$\small\text{largest number} - \text{smallest number}$
