Which R value represents the weakest correlations?
The correlation between two variables is considered to be weak if the absolute value of r is between 0.25 and 0.5.
Which R value represents the strongest correlation?
+1 Generally, correlation coefficients range between -1.00 to +1.00. According to the rule of correlation coefficients, the strongest correlation is considered when the value is closest to +1 (positive correlation) or -1 (negative correlation).
Which of the following correlations is the weakest?
Answer and Explanation: (a) -0.15 represents the weakest correlation. The sign of the correlation just indicates the type of relationship that exists between the two…
Is 0.3 A possible R value?
Correlation coefficient values below 0.3 are considered to be weak; 0.3-0.7 are moderate; >0.7 are strong.
Is 0.4 A weak correlation?
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 0.2 A weak correlation?
The magnitude of the correlation coefficient indicates the strength of the association. For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association.
Which of the following is the value of r if the strength of correlation is weak positive correlation?
r is always a number between -1 and 1. r > 0 indicates a positive association. r < 0 indicates a negative association. Values of r near 0 indicate a very weak linear relationship.
Which of the following values of r indicates the strongest correlation quizlet?
The correlation coefficient, often expressed as r, indicates a measure of the direction and strength of a relationship between two variables. When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables.
Which correlation coefficient represents the weakest relationship quizlet?
+0.10 is the weakest. Explain why a correlation coefficient of 0.00 or close to 0.00 may not mean that there is no relationship between the variables. a correlation coefficient of . 00 or close to .
What is a possible r value?
Possible values of the correlation coefficient range from -1 to +1, with -1 indicating a perfectly linear negative, i.e., inverse, correlation (sloping downward) and +1 indicating a perfectly linear positive correlation (sloping upward).
Is 0.3 A weak correlation?
Values between 0 and 0.3 (0 and −0.3) indicate a weak positive (negative) linear relationship through a shaky linear rule.
Is 0.4 A good r value?
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.
Is 0.67 A strong correlation?
Correlation Coefficient = 0.8: A fairly strong positive relationship. Correlation Coefficient = 0.6: A moderate positive relationship.
Is r 0.2 a strong correlation?
The magnitude of the correlation coefficient indicates the strength of the association. For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association.
Is 0.4 A strong correlation?
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 0.6 A strong correlation?
If we wish to label the strength of the association, for absolute values of r, 0-0.19 is regarded as very weak, 0.2-0.39 as weak, 0.40-0.59 as moderate, 0.6-0.79 as strong and 0.8-1 as very strong correlation, but these are rather arbitrary limits, and the context of the results should be considered.
Which r value suggests a weak positive correlation?
0.10 For example, a correlation of -0.97 is a strong negative correlation, whereas a correlation of 0.10 indicates a weak positive correlation.
Is an r of stronger than an r of 50 quizlet?
50 indicates a stronger degree of linear relationship than one of r=. 40. Likewise a correlation coefficient of r=-. 50 shows a greater degree of relationship than one of r=.
Which correlation would be considered the weakest or least strong?
A correlation is a statistical measurement of the relationship between two variables. 2 Remember this handy rule: The closer the correlation is to 0, the weaker it is. The closer it is to +/-1, the stronger it is.
Which value represents the strongest negative correlation?
Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1.0, while a 0 indicates no correlation, and +1.0 indicates a perfect positive correlation.
What is the highest R-value?
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
Is a higher R-value better?
The R-value for insulation is a way to measure how much resistance the insulation has to heat flow. The higher the R-value, the more the resistance and the better the material is at insulating a home.
What does an R value of 0.4 mean?
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.
What does R value 0.5 mean?
Correlation coefficients whose magnitude are between 0.5 and 0.7 indicate variables which can be considered moderately correlated. Correlation coefficients whose magnitude are between 0.3 and 0.5 indicate variables which have a low correlation.
Is .64 a strong correlation?
Strength of relationship The correlation between two variables is considered to be strong if the absolute value of r is greater than 0.75.
Is 0.08 a weak correlation?
A coefficient of correlation of +0.8 or -0.8 indicates a strong correlation between the independent variable and the dependent variable. An r of +0.20 or -0.20 indicates a weak correlation between the variables.
Which value of r indicates a stronger correlation than 40?
=.50 A correlation coefficient of r=. 50 indicates a stronger degree of linear relationship than one of r=. 40. Likewise a correlation coefficient of r=-.
Is a weak negative correlation?
A negative correlation indicates two variables that tend to move in opposite directions. A correlation coefficient of -0.8 or lower indicates a strong negative relationship, while a coefficient of -0.3 or lower indicates a very weak one.
What is weak positive correlation?
A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.
What is the lowest R-value insulation?
Here are the most common insulation materials listed in order of lowest to highest R-value: Cellulose: Loose-fill cellulose is rated between R-3.2 and R-3.9 per inch, making it one of the least efficient insulation materials available.
