WebWhen you sort a set of data and divide it into equal parts so that each part contains the same number of values, these cut-off points are called quantiles. For instance, when a set of data is divided into five equal parts, each of them is called a quintile, which refers both to the cut-off points as well as the group of values contained. WebThe formula for quantiles given in the book is rn/q + 1/2 where n is the number of observations, r is the rth quantile and q is the number of quantiles. So to calculate the 25th percentile of 10 observations would be 25x10/100 + 1/2 which is the 3rd observation. If I sketch this out on paper it seems reasonable I suppose. flat to rent in oudtshoorn
