Variance & Standard Deviation Calculator

This project implements a statistical analysis tool in C to calculate dispersion metrics for a random dataset.

⚙️ Formulas

1. Mean ($\mu$): $\frac{\sum x}{N}$
2. Variance ($\sigma^2$): $\frac{\sum (x - \mu)^2}{N}$
3. Standard Deviation ($\sigma$): $\sqrt{\text{Variance}}$

💻 Usage

The function Istatistik_Hesapla(array, n, mode) operates based on the mode:

• Mode 1: Returns Variance.
• Mode 0: Returns Standard Deviation.

🚀 Example Output

Based on Question 7: N=5, Array: {10, 20, 30, 40, 50}

• Mean: 30
• Squared Diff Sum: $400 + 100 + 0 + 100 + 400 = 1000$
• Variance: $1000 / 5 = 200.0$
• Std Dev: $\sqrt{200} \approx 14.14$
