Correlation Coefficient | Karl Pearson's correlation coefficient| with real life example

Описание: 📊 Correlation Coefficient (r) Explained | How to Calculate with Example + Exercise

In this video, we break down the correlation coefficient (r)—a statistical measure that shows the strength and direction of a linear relationship between two variables. You'll learn:

✅ What the correlation coefficient means
✅ How to interpret the value of r
✅ Step-by-step calculation of r using a real example
✅ One exercise question for you to solve and test your understanding

📘 What You'll Learn:

Meaning of the correlation coefficient

How values of r range from –1 to +1

Interpretation:
• r = +1 → perfect positive correlation
• r = –1 → perfect negative correlation
• r = 0 → no linear correlation
