Maximum
Shows the largest value in a dataset, useful for identifying the upper boundary of observed data.
Minimum
Displays the smallest value in a dataset, helping to determine the lower boundary of observed data.
Sample

Population
The entire group of interest in a study, requiring distinct statistical formulas compared to samples.
Central Tendency
Describes the center or typical value of a dataset, commonly measured by mean, median, or mode.
Variability
Indicates how spread out or dispersed data values are, often measured by standard deviation.
Formula Bar
The area in Excel where functions and formulas are entered to perform calculations on selected data.
Cell Range
