# Topic: Quartile

 [No title] Similarly, the.75 quantile (also referred to as the 75th percentile or upper quartile) is a value such that 75% of the values of the variable fall below that value and is calculated accordingly. The quartile (this term was first used by Galton, 1882) range of a variable is calculated as the value of the 75th percentile minus the value of the 25th percentile. The lower and upper quartiles (this term was first used by Galton, 1882; also referred to as the.25 and.75 quantiles) are the 25th and 75th percentiles of the distribution (respectively). www.statsoft.com /textbook/glosq.html   (2080 words)

 Quartile - Wikipedia, the free encyclopedia In descriptive statistics, a quartile is any of the three values which divide the sorted data set into four equal parts, so that each part represents 1/4th of the sample or population. The difference between the upper and lower quartiles is called the interquartile range.

In both of the above cases, the first and third quartiles can be taken to be the median values of the lower and upper halves of the data, respectively. However, there is more than one school of thought on how to apply this definition when the overall median is one of the original data values. su.wikipedia.org /wiki/Quartile   (466 words)

 Math Forum - Ask Dr. Math   (Site not responding. Last check: 2007-10-23) The upper quartile is the part containing the highest data values, the upper middle quartile is the part containing the next-highest data values, the lower quartile is the part containing the lowest data values, while the lower middle quartile is the part containing the next- lowest data values. The term 'quartiles' is sometimes used to collectively refer to these values plus the median (which is the cut-off value between the upper middle quartile subset and the lower middle quartile subset). Furthermore, if the quartile value is not required to be a point in the data set itself, most data sets don't have a unique set of values {Q1, Q2, Q3} that divides the data into four "roughly equal" portions. mathforum.org /library/drmath/view/60969.html   (1583 words)

 FPA Journal - Does Slow and Steady Win the Race? Not Quite. by Mark Riepe For each fund we counted how many individual years of the five years (1996–2000) the fund finished in the second quartile of its group as specified at the beginning (that is, year-end 1996) as well as calculating their cumulative five-year percentile rank. At this point we've established that the hyper-consistent funds that have managed to be second quartile for five straight years just barely turn in top quartile performance on a cumulative basis and that assumes the most aggressive adjustment for survivor bias. As for the funds that have managed to be second quartile four of five years, we have far more of them, but even after our survivor bias adjustment, the average cumulative performance percentile rank isn't top quartile. www.fpanet.org /journal/articles/2005_Issues/jfp0805-art2.cfm   (1353 words)

 [No title] The interquartile range is the range between the first quartile and the third quartile. If the value is greater than the third quartile plus 1.5 x the interquartile range (IQR) or less than the first quartile minus 1.5 x the IQR it is considered a moderate outlier. If the outlier is greater than the third quartile plus 3 x IQR or less than the first quartile minus 3 x IQR, it is considered an extreme outlier. www.cs.indiana.edu /classes/a113-dger/fall2003/lectures/Chapter_04.doc   (2023 words)
