Question

If a correlation coefficient of -0.898 is given for comparing two things, what does this number tell you about the correlation of the two things?
strong positive


strong negative


weak negative


no correlation

Answer 1

Answer: Strong negative

Step-by-step explanation:

Correlation coefficient tells about the strength ( Strong , moderate or weak ) and direction ( positive or negative) of the relationship between two quantities.

• Strong correlation: The value of correlation coefficient lies between -1 to -0.5 or 0.5 to 1.
• Moderate correlation : The value of correlation coefficient lies between -0.5 to -0.3 or 0.3 to 0.5.
• Weak correlation : The value of correlation coefficient lies between -0.3 to -0.1 or 0.1 to 3.

The given correlation coefficient :-0.898

Since, it lies between -1 and -0.5 and has negative sign, it means it indicates a strong negative  between the two things.

Hence, the correct answer is "strong negative ".
