csyang2 1:c0f972361605 85 * to calculate the median of the samples so that wild outliers
csyang2 1:c0f972361605 86 * don't skew the result. First off, let's assume that arrays
csyang2 1:c0f972361605 87 * are one-based instead of zero-based. If this were the case
csyang2 1:c0f972361605 88 * and index was odd, we would need sample number ((index+1)/2)
csyang2 1:c0f972361605 89 * of a sorted array; if index was even, we would need the
csyang2 1:c0f972361605 90 * average of sample number (index/2) and sample number
csyang2 1:c0f972361605 91 * ((index/2)+1). To turn this into something useful for the
csyang2 1:c0f972361605 92 * real world, we just need to subtract one off of the sample
csyang2 1:c0f972361605 93 * numbers. So for when index is odd, we need sample number
csyang2 1:c0f972361605 94 * (((index+1)/2)-1). Due to integer division truncation, we
csyang2 1:c0f972361605 95 * can simplify this to just (index/2). When index is even, we
csyang2 1:c0f972361605 96 * need the average of sample number ((index/2)-1) and sample
csyang2 1:c0f972361605 97 * number (index/2). Calculate (index/2) now and we'll handle
csyang2 1:c0f972361605 98 * the even odd stuff after we sort.
