What is an example of a third variable correlation?
an example of third variable correlation would be something like a lack of adult supervision (the 3rd variable) would cause watching televised violence and aggressiveness. There are still two other variables that are in relation to each other, but they probably would not occur unless the 3rd variable was there (which is the lack of parents).
Who is the first discovered the relation between motion and force?
the answer is sir. isaac newton galileo galilei explained only the relation between motion and force
What is Conclusion on one compartment open model?
lineaar relation
What is starvation in relation to extinguishing fire?
removing the fuel or source of ignition.
What is the relationship of history to other sciences?
relation of history to other sciences
What is multiple correlation coefficient and partial correlation coefficient?
partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
What are the uses of Pearson correlation coefficient?
The nominal variant will be for males (1) and for females (3) to identify the relation in the study.
How change of origin or scale effect value of co-efficient of co-relation?
The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.
When is the correlation coefficient zero?
The correlation coefficient is zero when there is no linear relationship between two variables, meaning they are not related in a linear fashion. This indicates that changes in one variable do not predict or explain changes in the other variable.
Is r0.45 a strong correlation?
No, it's a small enough value that it doesn't suggest any correlation at all. There's no hard-and-fast rule for interpreting the correlation coefficient: a very strong correlation in one discipline might be considered weak in others, and the correlation coefficient might be misleading in some cases. But most of the time, you want r to be at least plus or minus 0.9 before even thinking about any relation between the data.
What does Pearson's linear correlation coefficient measure?
Strength and direction of linear relation. Closer to 1 is positive linear association, closer to -1 is positive negative association and closer to 0 means no linear relation. Remember that 0 does not mean that there is no relation - just no linear relation.
Explain the relation between sunk costs and specificity?
Specificity refers to the percentage of an investment that will be lost if the asset is switched to another use. Sunk cost is a cost that cannot be avoided once incurred. The relation between them is
What is the medical term meaning state of having a fixed relation to a pathogen?
Specificity
What is the relation of Figure of merit with current sensitivity?
Figure of merit = 1/ Current Sensitivity.
What is biochemical correlation?
Biochemical correlation refers to the statistical relation between two or more biochemical variables.
Which correlation coefficient best describes the relation between X and Y below X10 20 30 40 50 Y 80 70 60 50 40 a -1 b 1?
-1. Y falls as X rises. In fact the PMCC is precisely -1 (i.e. a perfect negative correlation).
What will be the correlation for the graph of this equation y equals 14x?
Since y=14x is a perfect linear relation, the correlation would be 1.
