which best describes the strength of a model with an r - value of 0.29?\n○ a weak positive correlation\n○ a strong positive correlation\n○ a weak negative correlation\n○ a strong negative correlation

Answer

Explanation:

Step1: Understand r - value range

The correlation coefficient (r) ranges from - 1 to 1. Positive values of (r) indicate positive correlation (as one variable increases, the other increases), and negative values indicate negative correlation (as one variable increases, the other decreases).

Step2: Determine strength based on magnitude

The closer (|r|) is to 1, the stronger the correlation. When (|r|) is close to 0, the correlation is weak. Since (r = 0.29) (a positive value), it is a positive correlation, and since (|0.29|) is far from 1 and close to 0, it is a weak correlation.

Answer:

a weak positive correlation
