A correlation coefficient of . 10 is thought to represent a weak or small association; a correlation coefficient of . 30 is considered a moderate correlation; and a correlation coefficient of . 50 or larger is thought to represent a strong or large correlation.
What is a strong correlation?
The relationship between two variables is generally considered strong when their r value is larger than 0.7. The correlation r measures the strength of the linear relationship between two quantitative variables.
Is .78 a strong correlation?
Numbers can range from –1.00 (a perfect negative correlation) to 1.00 (a perfect positive correlation. … For example, a correlation of -. 78 is for stronger than one of . 23.
What are examples of strong correlations?
Positive Correlation Examples in Real Life
- The more time you spend running on a treadmill, the more calories you will burn.
- The longer your hair grows, the more shampoo you will need.
- The more money you save, the more financially secure you feel.
- As the temperature goes up, ice cream sales also go up.
Is 0.4 A strong correlation?
The sign of the correlation coefficient indicates the direction of the relationship. … For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak.
What is a strong and weak correlation?
A correlation of -0.97 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation. … When you are thinking about correlation, just remember this handy rule: The closer the correlation is to 0, the weaker it is, while the closer it is to +/-1, the stronger it is.
Is 0.2 A strong correlation?
There is no rule for determining what size of correlation is considered strong, moderate or weak. … For this kind of data, we generally consider correlations above 0.4 to be relatively strong; correlations between 0.2 and 0.4 are moderate, and those below 0.2 are considered weak.
Is .23 a strong correlation?
A correlation of . 23 could be very meaningful depending on context. A correlation of 0.8 and n = 10 is not really hugely meaningful because of noise (though it is statistically significant).
Is .36 a strong correlation?
All Answers (10) correlation value of 0.6 is moderate value. The square of correlation value is 0.36 which means 36% of the dependent variable can be explained by the independent variable.
Which of the following represents the strongest correlation?
Answer: -0.85 (Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others.
Is 0.8 A strong correlation?
Correlation Coefficient = 0.8: A fairly strong positive relationship. Correlation Coefficient = 0.6: A moderate positive relationship. Correlation Coefficient = 0: No relationship. As one value increases, there is no tendency for the other value to change in a specific direction.
Is 0.5 A strong correlation?
Correlation coefficients whose magnitude are between 0.7 and 0.9 indicate variables which can be considered highly correlated. Correlation coefficients whose magnitude are between 0.5 and 0.7 indicate variables which can be considered moderately correlated.
Is 0.49 A strong correlation?
High degree: If the coefficient value lies between ± 0.50 and ± 1, then it is said to be a strong correlation. Moderate degree: If the value lies between ± 0.30 and ± 0.49, then it is said to be a medium correlation. Low degree: When the value lies below + . 29, then it is said to be a small correlation.
Is 0.48 A strong correlation?
For a natural/social/economics science student, a correlation coefficient higher than 0.6 is enough. Correlation coefficient values below 0.3 are considered to be weak; 0.3-0.7 are moderate; >0.7 are strong.
Is 0.44 A strong correlation?
Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation.
