Answer:
is the number dividing the third and fourth quartile. The upper quartile can also be thought of as the median of the upper half of the numbers. The upper quartile is also called the 75th percentile; it splits the lowest 75% of data from the highest 25%
Sometimes, the formula will result in an answer that is not a whole number and does not end in .5. If this is the case, then subtract the answer by .25 and then follow the earlier provided rules. An example would be a set with 10 elements. Using the formula results in an answer of 8.25. This should be subtracted by .25 to yield 8, meaning the 8th term would be the upper quartile. A similar example would be a data set with 4 items. Using the formula would give an answer of 3.75, which should be subtracted by a .25 to yield an answer of 3.5. The upper quartile will be the average of the 3rd and 4th terms.
