A quartile is a specific percentile. First, second, third quartiles are 25th, 50th and 75th percentiles respectively. As discussed in the percentile calculations post the position of the pth percentile item, i = (p/100) * n where n is the total numbers in the data sample.
Calculate these quartiles as described in the post. If a fund falls under top quartile (percentile greater than 75) is considered for investment.
