Question

1. if the correlation coefficient r = 0.98r = 0.98r = 0.98, what does this indicate? a) weak negative relationship b) strong positive relationship c) no relationship

Explanation:

The correlation coefficient \( r \) measures the strength and direction of a linear relationship between two variables. The value of \( r \) ranges from \(- 1\) to \(1\). A positive \( r \) value indicates a positive relationship (as one variable increases, the other tends to increase). The closer \( r \) is to \(1\) (or \(-1\)), the stronger the relationship. Since \(r = 0.98\) is close to \(1\) and positive, it shows a strong positive relationship.

Answer:

B. Strong positive relationship
