  • How do you indicate to Excel that you want to perform a calculation using a function?
    You start the formula with an equal sign (=) followed by the function name and an open parenthesis.
  • What is the Excel function for finding the mean (average) of a dataset?
    The function =AVERAGE() is used to find the mean in Excel.
  • Which Excel function calculates the standard deviation for a sample?
    The function =STDEV() calculates the sample standard deviation in Excel.
  • How do you modify the standard deviation function in Excel to calculate for a population instead of a sample?
    You use =STDEV.P() to calculate the population standard deviation in Excel.
  • What function would you use in Excel to find the maximum value in a dataset?
    You use =MAX() to find the maximum value in a dataset.
  • How can you select a range of data for a function in Excel?

  • What is the result of using =STDEV() on sample data in Excel?
    It returns the sample standard deviation of the selected data.
  • Why is it important to know whether your data is a sample or a population when using Excel’s standard deviation functions?
    Because Excel uses different formulas for sample (=STDEV()) and population (=STDEV.P()) standard deviation, affecting the result.
