There is no direct formula to calculate the IQR in Excel, however, it is relatively straight forward to do. The easiest approach is to firstly calculate the Q1 and Q3 and then use these to determine the IQR. Below is the steps recommended to calculate the IQR in Excel. ...
Lower bound = Q1 - (1.5 * IQR) Upper bound = Q3 + (1.5 * IQR) The 1.5 might look arbitrary, but it has mathematical significance. If you are interested in its detailed math, look at this article You need to know that this is roughly equivalent to finding data at least 3 standard...
