Condition for Calculating Measures of Central Tendency in Java
Description:Calculating the measures of central tendency for a data set involves finding the mean, median, and mode. In Java, you can use basic data structures like arrays and collections to compute these values. The mean is calculated by summing the data points and dividing by the number of elements, while the median is the middle value of a sorted data set, with special handling for even-sized arrays. The mode is computed using a frequency map, which identifies the most frequently occurring values in the dataset. This approach provides an accurate and efficient way to analyze data and is implemented with standard Java libraries.
Sample Source Code
# CentralTendency.java package JavaSamples2;
import java.util.*;
public class CentralTendency {
public static double calculateMean(int[] data) { double sum = 0; for (int num : data) { sum += num; } return sum / data.length; }
public static double calculateMedian(int[] data) { Arrays.sort(data); // Sort the data in ascending order int length = data.length;
