What does a correlation factor of -0.95 mean?
This means that the correlation is negative but still significant.
What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
What is the correlation on a graph?
a correlation on a graph is when the line of best fit is positive, negative or none.
If two variables have a negative linear correlation is the slope of the least squares negative?
Negative
Difference between positive and negative correlation?
If the two variables increase together and decrease together AND in a linear fashion, the correlation is positive. If one increases when the other decreases, again, in a linear fashion, the correlation is negative.
When are is close to -1 does it indicate a weak negative correlation?
No, it indicates an extremely strong positive correlation.
When are is close to -1 does it indicate a strong negative correlation?
Yes.
Does a negative correlation coefficient indicate an inverse relationship?
Yes, but the relationship need not be causal.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
What does a correlation coefficient value of negative two indicate?
A mistake in calculations! ;) If the calculations are done correctly then the sample correlation must lie within the closed interval [-1, 1].
What does the sign of the correlation coefficient tell you about the association?
Positive correlation = positive association Negative correlation = negative association
Are negative correlation and reverse correlation same?
No.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Is -.187 a positive or negative correlation?
It's a negative correlation because it is less than 0
Is certain a negative connotation or positive correlation?
A positive correlation.
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What are the trends of a line?
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
