[D Biology Classroom] CAIE A-level biology 9700
What is Pearson's correlation coefficient? How to use it for problem-solving?
*** At 2:35, I made a mistake by writing 294100 as 29410. However, the calculation is correct. My apology for that !!
*** In the 2022-2024 syllabus, the formula is changed to (n-1)SxSy, no longer nSxSy as shown in this video. Do take note of that!
