Question

Strength involves calculating the ___________ r.

Group of answer choices

regression

correlation

pattern

trend

Answer 1

Strength involves calculating the correlation coefficient r.

The strength can be either strongly positive(negative) or moderately positive (negative) or weakly positive (negative)

If r ranges from [-1,0) it indicates negative correlation with more strength if the value is towards -1

And if r ranges from (0,1], it indicates positive correlation with more strength if the value is towards 1

Whereas, regression, pattern and trend do not include strength. Regression predicts value for a variable based on a dependent variable. While pattern and trend indicates shapes and direction.
