What are some basic statistics concepts in C++?

What are some basic statistics concepts I should know for C++ programming?

In C++, basic statistics concepts include mean, median, mode, variance, and standard deviation. Would you like to dive deeper into any of these?

Can you explain how to calculate the mean in C++?

To calculate the mean, sum all the values in your dataset and divide by the number of values. Here's a simple code snippet:

#include <iostream>
#include <vector>

float calculateMean(const std::vector<int>& data) {
    float sum = 0;
    for (int num : data) {
        sum += num;
    }
    return sum / data.size();
}

Would you like to see examples of the other concepts?

Yes, please show me how to calculate the standard deviation.

To calculate the standard deviation, first find the mean, then calculate the variance by averaging the squared differences from the mean, and finally take the square root of the variance. Here's a code example:

#include <cmath>
#include <vector>

float calculateStandardDeviation(const std::vector<int>& data) {
    float mean = calculateMean(data);
    float variance = 0;
    for (int num : data) {
        variance += (num - mean) * (num - mean);
    }
    variance /= data.size();
    return std::sqrt(variance);
}
