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

You should be familiar with concepts like mean, median, mode, variance, and standard deviation.

Can you explain the difference between variance and standard deviation?

Variance measures the spread of data points, while standard deviation is the square root of variance, indicating dispersion.

How can I calculate the mean in C++?

To calculate the mean, sum all the values and divide by the number of values. Would you like a code example?

Yes, please provide a code example for calculating the mean.

Here's a simple example:

#include <iostream>
#include <vector>

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