Question

what does the correlation coefficient reveal about the data if describes...strong or not strong? 2. answer: 3. answer:

Explanation:

Step1: Recall the correlation coefficient rule

The closer the absolute value of the correlation coefficient \(r\) is to \(1\), the stronger the linear correlation.

Step2: Analyze \(r = - 0.284\)

\(\vert r\vert=\vert - 0.284\vert = 0.284\). Since \(0.284\) is far from \(1\), the correlation is not strong.

Step3: Analyze \(r = 0.984\)

\(\vert r\vert=\vert0.984\vert = 0.984\). Since \(0.984\) is very close to \(1\), the correlation is strong.

Answer:

  1. NOT STRONG
  2. STRONG
