WebThe interquartile range is the section of data between the lower and upper quartiles, comprising exactly 50% of the data. Much like the regular range, the IQR reflects how spread out a data set is: a lower IQR means that data is clustered closely around the median, while a large IQR suggests the data is more spread out. WebThe interquartile range (IQR) is the difference between the first and third quartiles. You can find the interquartile range using the formula: IQR=Q_ {3}\ –\ Q_ {1} I QR = Q3 – Q1. Then, using the quartiles and interquartile range, set fences beyond the quartiles. Any values outside of these fences are considered outliers. WebThe formula for finding the interquartile range takes the third quartile value and subtracts the first quartile value. IQR = Q3 – Q1. Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data). Using the IQR formula, we need to find the values for Q3 and Q1. dworc fleshunter tibia
