Can a correlation equal to 3?
A correlation coefficient cannot exceed 1.
Does correlation always equal causation?
No! Correlation by itself is not sufficient to infer or prove causation.
If the correlation coefficient r is equal to 0.35 find the coefficient of nondetermination?
The coefficient of nondetermination is found by 1.00-r squared so 1.00-0.35X0.35 1.00-0.1225 0.8772 round it to 0.88
If coefficient of correlation r between two variables is zero does it mean that there is no relationship between the variables Justify your answer?
"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".
What plus and minus signs mean in correlation mean?
They equal a minus and two +'s or two -'s equal a + :)
What type of correlation do you have when are is equal to one?
A correlation coefficient of 1 (r=1) is a perfect positive correlation.
What is the value of correlation coefficient r for perfect positive correlation?
1.
What is the correlation if x values are equal to the y values?
Positive Correlation
Can a correlation equal to 3?
A correlation coefficient cannot exceed 1.
Does statistical correlation r have units?
No, r is a coefficient.
What is the feasible range for r the correlation coefficient?
the correlation coefficient range is -1 to +1
Does correlation always equal causation?
No! Correlation by itself is not sufficient to infer or prove causation.
If the correlation coefficient r is equal to 0.35 find the coefficient of nondetermination?
The coefficient of nondetermination is found by 1.00-r squared so 1.00-0.35X0.35 1.00-0.1225 0.8772 round it to 0.88
Interpret an r value of 0.11?
a strong negative correlation* * * * *No it is not. It is a very weak positive correlation.
Is r equal .12 a strong correlation in social sciences?
A correlation of .12 is considered weak in social sciences. It suggests that there is a very minor relationship between the variables being studied. Strong correlations are typically closer to 1 or -1.
Which is the stronger correlation?
The stronger correlation will be the one whose absolute value is closest to one. For example, r = -.78 is stronger than r=.65, because: |r| = |-.78| = .78 > |r| = |.65| = .65
What does the science symbol r mean?
In science, the symbol "r" typically refers to the correlation coefficient, which measures the strength and direction of a relationship between two variables. It ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.
