✍️ Suggested Video Description
🔎 In this video, we explore hypothesis testing with Pearson’s correlation coefficient (PMCC). You’ll learn how to:
Set up null and alternative hypotheses for correlation.
Use the sample size
𝑛
n to find the critical value.
Apply the level of significance (α) to decide whether to reject or accept the null hypothesis.
Interpret correlation results in real-world examples.
📊 This tutorial is perfect for statistics students preparing for exams or anyone wanting a clear explanation of how to test if a correlation is statistically significant.
✅ Topics covered:
PMCC definition and formula
Hypotheses:
Finding the critical value from
n and significance level
Step-by-step decision-making process
💡 By the end, you’ll confidently know when a correlation is significant and when it could be due to random chance.
