Given two integers mean and mode, representing the Mean and Mode of a random group of data, the task is to calculate the median of that group of data.
Input: mean = 3, mode = 6
Output: 4Input: mean = 1, mode = 1
Output : 1
Approach: The given problem can be solved by using the mathematical relationship between mean, mode, and median of the group of data. Below is the relationship among them:
=>
=>
Therefore, the idea is to use the above formula to find the median of the data when the mean and the mode are given.
Below is the implementation of the above approach:
C++
// C++ program for the above approach#include <bits/stdc++.h>using namespace std;// Function to find the median of a// group of data with given mean and modevoid findMedian(int Mean, int Mode){ // Calculate the median double Median = (2 * Mean + Mode) / 3.0; // Print the median cout << Median;}// Driver Codeint main(){ int mode = 6, mean = 3; findMedian(mean, mode); return 0;} |
Java
// Java program for the above approachimport java.util.*;class GFG{// Function to find the median of a// group of data with given mean and modestatic void findMedian(int Mean, int Mode){ // Calculate the median double Median = (2 * Mean + Mode) / 3.0; // Print the median System.out.print((int)Median);}// Driver codepublic static void main (String[] args){ int mode = 6, mean = 3; findMedian(mean, mode);}}// This code is contributed by code_hunt |
