I use the QUARTILE.INC function to calculate quartiles for a data set. The function takes a single argument, which is the range of cells containing the data set. It then returns the quartiles for the data set as numbers in the range 0 to 3.
The syntax of the QUARTILE.INC function in Microsoft Excel is as follows:
The QUARTILE.INC function returns the quartile of the values in the supplied array. The quartile is the value that separates the lower 25% of the values from the upper 75% of the values. If the array contains fewer than 25 values, the quartile returned is the median of the values in the array.
QUARTILE.INC can be used in Excel to calculate quartiles for a set of data. The function takes a single input, which is the range of cells that contains the data you want to calculate the quartiles for. The quartiles are then calculated and returned as a series of numbers in the range A1:A4. The first quartile is returned in A1, the second quartile is returned in A2, the third quartile is returned in A3, and the fourth quartile is returned in A4.
There are a few occasions when you should not use the QUARTILE.INC function in Excel. One instance would be when you have a list of data that is not sorted in ascending order. If the data is not sorted, the function will not produce accurate results. Another time you should not use the function is when you have fewer than four data points. In this case, the function will not be able to produce any results.
There are a few similar formulae to QUARTILE.INC in Excel. One such formula is Quartile.rank(), which will give you the quartile rank of a given value. This formula takes into account the values in the entire dataset, not just the values in the current row or column. Another similar formula is Quartile.Inv(), which will give you the inverse of the quartile rank. This formula takes into account the values in the entire dataset, not just the values in the current row or column. Yet another similar formula is Quartile.stats(), which will give you some basic statistics about the quartiles in a given dataset. This formula takes into account the values in the entire dataset, not just the values in the current row or column.
