and $$Q3=\frac{3.54, 3.54}{2}=3.54 $$ Example of Calculating Quartiles When the Data Size is Even Find the lower and upper quartiles of the test scores $$75,58,69,80,87,77,91,67 $$ Step 1: Order the data values from smallest to largest. The ordered list of test scores is ...
While the above procedure works, you may want to use the lower and upper quartile formulas for larger data sets. Upper and lower quartiles The upper quartile (sometimes called Q3) is the number dividing the third and fourth quartile. The upper quartile can also be thought of as themedianof...
A quartile is a statistical term that describes a division of observations into four defined intervals based on the values of the data and how they compare to the entire set of observations. Quartiles are organized into lower quartiles, median quartiles, and upper quartiles. When the data poi...
You can also find the upper and lower values by using theLARGEandSMALLfunctions, respectively. These functions allow you to determine thekthlargest or smallest value in a dataset. Find the Lower Value: Go to cellE5and enter the formula: =SMALL(C5:C15,1) TheSMALLfunction searches for the1st...
UPPER_LIMIT = [QUARTILE3]+1.5*[IQR] and now I'd like to compare each individual Sales value with the [LOWER_LIMIT] and [UPPER_LIMIT] for a given customer and a given product. I can't seem to figure it out. If I just do a calculated column that compares Table[Sales] with...
How to Find an Outlier in Google Sheets If all of the above sounds like a bit too much math for your liking, never fear. Google Sheets does all the hard work for you. It will help you to calculate the upper quartile, lower quartile, and interquartile range for your data, and you ca...

Lower whisker boundary – Q1 – 1,5 * IQR Upper whisker boundary – Q3 + 1,5 * IQR We will return to our array again and implement this way of detecting outliers. First, we will calculate the first and third quartile. Then with those two values, we can calculate the interquartile ran...
To calculate the Interquartile Range (IQR) in Excel using VBA and prompt the user to select the range, you can use the followingVBA code. This code first asks the user to select a range of data. Then, it calculates the IQR by subtracting the 1st quartile (25th percentile) from the 3rd...
