Data that has this pattern are said to be bell-shaped or have a normal ... The 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. percentile = (number of ranks below x/total number of ranks) X 100. For example, in the table above, the number 58 with a rank = 6. Number of ranks below 58 = 5, total number of ranks = 50. The percentile for 58 = (5/50)X 100 = 10th. Using that formula, we can calculate the percentiles for all numbers in our data.Measurement refers to careful, deliberate observations of the real world and is the essence of empirical research.
