Let's try using this knowledge to find the interquartile range for a data set in the following two examples. The first example will show how to find the IQR with an odd number of values in a data set, while the second example will show how to find the IQR with an even number o...
The interquartile range (IQR), represents the middle 50 percent of a data set. To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number...
2. Next, we need to calculate Q3. To calculate Q3 in Excel, simply find an empty cell and enter the formula ‘=QUARTILE(array, 3)‘. Again, replacing the ‘array‘ part with the cells that contain the data of interest. 3. Finally, to calculate the IQR, simply subtract the Q1 value...
In Python, we can use the NumPy function percentile() to find Q1 and Q3 and then find the IQR. Q1 = np.percentile(df_boston["DIS"], 25, interpolation="midpoint") Q3 = np.percentile(df_boston["DIS"], 75, interpolation="midpoint") IQR = Q3 - Q1 In our dataset, we print the...

Low outliers would be values less than 1.5*IQR (Q1-1.5*IQR), and high outliers would be values greater than 1.5*IQR (Q3+1.5*IQR). Outliers appear in the box plots as + symbols. The first page of the report compares the variables (the Analysis Fields) within each group to each other...
