Interquartile Range (IQR): What it is and How to Find it
WebCalculation of Q1 can be done as follows, Q1 = ¼ (9 + 1) =¼ (10) Q1 = 2.5 Term Calculation of Q3 can be done as follows, Q3=¾ (9 + 1) =¾ (10) Q3 = 7.5 Term Calculation of quartile deviation can be done as follows, Q1 is an average of 2nd, which is 11, and adds the difference between 3rd & 4th and 0.5, which is (12-11)*0.5 = 11.50. 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. WebJul 25, 2024 · Q1 = 6,Q3 = 10 Explanation: We require the data to be in ascending order 1,x4,x6,x6,x6, ↑ x7,x9,x10,x11,x14 Find the median of the data set the median is the middle entry in the data set. If not a value then the average of the values either side of the middle In this case the median = 6 +7 2 = 6.5 shark rv2610wfus
