Are negative correlation and reverse correlation same?
No.
Can the variance of a sample be negaTIve?
No.
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What is a negative correlation?
A negative correlation is a measure of the linear component of a relationship where one variable increase as the other decrease.
What a correlation of 0.30 means that the independent variable explains -- percent of the variance in the dependent variable?
The independent variable explains .32*100 percent of the variance in the dependent variable.This is 9%.The explainable variance is always the square of the correlation (r).
What is the difference between negative price variance and volume variance?
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
Can variance be negative?
Since Variance is the average of the squared distanced from the mean, Variance must be a non negative number.
