How to Find Quartiles in R, A dataset is divided into four equal halves using values known as quartiles. The first quartile of a dataset corresponds to the 25th percentile. The second quartile of a dataset serves as a proxy for the 50th percentile. This sum corresponds to the median value...
These are also referred to as quartiles, and the interquartile range is the region between the 25th and 75th percentiles. This calculation’s methodology is the same as that used to determine the percentile value. How to Calculate Percentiles in R How then may percentiles be found in R? Usi...
