median() method from fcf::NTest::HistogramBasic class

TItem median() const

Available from version: 1.2.5

Calculates the estimated median value of the distribution.

The median method calculates the median of the data points currently stored in the histogram. Since the histogram uses bins, the median is an estimated value based on the distribution across those bins.

Result

TItem

- The estimated median value.

Example: Calculating Median

Finding the median of a simple distribution.

#define FCF_TEST_IMPLEMENTATION #include <fcfTest/test.hpp> #include <iostream> FCF_TEST_DEFINE("HistogramDemo", "Stats", "MedianTest") { fcf::NTest::HistogramBasic<int> hist(10, 0, 100); // Add values: 10, 20, 30, 40, 50 hist.append(10); hist.append(20); hist.append(30); hist.append(40); hist.append(50); int med = hist.median(); fcf::NTest::log() << "Median: " << med << std::endl; FCF_TEST(med == 30); } int main(int a_argc, char* a_argv[]) { bool error = false; fcf::NTest::cmdRun(a_argc, a_argv, fcf::NTest::CRM_RUN, &error); return error ? 1 : 0; }

Output:
