IQR = Interquartile range These equations give you two values, or “fences“. You can think of them as a fence that cordons off the outliers from all of the values that are contained in the bulk of the data. Example question:Use Tukey’s method to find outliers for the following set ...
the 50th percentile (the median) and the 75th percentile. The calculator then subtracts the 75th percentile from the 25th percentile to find the interquartile range using the formula Q3– Q1= IQR. Just type your numbers into the text box and click the “Find the interquartile range” button...

Each pixel plays an important role. For example, alignment markers—the small squares with dots in the middle—help your device figure out the QR Code’s orientation and size. Meanwhile, the black-and-white modules running horizontally and vertically through the center act as a timing pattern, ...
