  • Descriptive Statistics
    Summarizes and presents key features of a dataset, including central tendency and variability, to simplify data interpretation.
  • Mean
    Represents the average value of a dataset, calculated by dividing the sum of all values by the number of values.
  • Median
    Identifies the middle value in a sorted dataset, providing a measure of central tendency less affected by outliers.
  • Mode
    Highlights the value(s) that appear most frequently in a dataset, useful for identifying common outcomes.
  • Standard Deviation
    Measures the spread of data values around the mean, indicating how much values typically differ from the average.
  • 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
    A subset of a population used for analysis, often requiring specific statistical formulas for accurate results.
  • 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
    A group of adjacent cells in Excel selected for analysis, often specified by starting and ending cell references.
  • Function
    A predefined operation in Excel that performs calculations or data analysis, such as finding averages or maximums.
  • Shortcut
    A quick method in Excel, like copying and pasting function names, to streamline repetitive tasks during data analysis.
