Percentiles can be defined as “greater than or equal to” (inclusive) or “greater than” (exclusive). The QUARTILE.INC function is inclusive and has “greater than or equal to” behavior. QUARTILE.EXC is exclusive, and has “greater than” behavior.  The screen below shows how QUARTILE.INC and QUARTILE.EXC return different results for the same data. Note QUARTILE.EXC cannot be used to get the minimum or maximum value like QUARTILE.INC. 

Note: Starting with Excel 2010, the QUARTILE.INC function replaces the QUARTILE function with the same behavior.
