Similarly, [math]Q_2[/math] is the second quartile (or the median, 50th percentile), and [math]Q_3[/math] is the upper quartile (or the third quartile, 75th percentile). Must not be confused with quantile because quantile is same as percentile.

The lower quartile value is the median of the lower half of the data. The upper quartile value is the median of the upper half of the data. This rule is employed by the TI-83 calculator boxplot and "1-Var Stats" functions. Method 2. Use the median to divide the ordered data set into two halves. If there are an odd number of data points in the original ordered data set, include the median (the how to find the equation of the best fit line Obtaining the quartiles: Typically you obtain quartiles from the data. Thus, you would have sample data (either your dataset or another dataset), and you can use software to give you .25 and .75 percentiles (or alternatively, you can get such values fairly straightforwardly by rank ordering the data).
