claudia records the hours she spent studying and her test scores for 5 tests. what is the correlation coefficient? 0.85 what is the strength of the model? strong positive correlation moderate positive correlation strong negative correlation moderate negative correlation

Answer

Explanation:

Step1: Recall correlation - strength criteria

Correlation coefficients range from - 1 to 1. Values close to 1 or - 1 indicate strong correlation, while values around 0.5 - 0.7 (positive or negative) indicate moderate correlation.

Step2: Analyze the given coefficient

The given correlation coefficient is 0.85. Since 0.85 is close to 1, it represents a strong positive correlation (as it is positive). Positive correlation means that as the number of hours spent studying increases, the test - scores also tend to increase.

Answer:

Strong positive correlation
