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 are adverse variances?
Adverse variances means unfavourable variance which is actual expenses are more than budgted variance.
What does homogeneity of variance mean?
It means that the variance remains the same across the range of values of the variable.
To conduct a t test for independent means ideally the populations should be both normally distributed and have the same?
The other assumptions are listed in the related link. The answer you are looking for is the same variance or standard deviation.
What is adverse variance?
A non favourable variance Eg: adverse revenue means the company earned less revenue than expected.
What is heteroscadacity?
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
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).
Purpose of variance analysis?
Variance analysis shows the deviation of an organization's financial performance from the set standard in the budget. An organization will promptly address the deviations.
What is cost variance?
Cost variance means the difference in actual cost from standard cost and very important part of standard costing and budgeting analysis.
Is ANOVA a qualitative or quantitative statistical analysis method?
ANOVA, which stands for Analysis of Variance, is a quantitative statistical analysis method used to compare means of three or more groups.
What are adverse variances?
Adverse variances means unfavourable variance which is actual expenses are more than budgted variance.
What does homogeneity of variance mean?
It means that the variance remains the same across the range of values of the variable.
Why is the variance of a distrubtion of means smaller than the original popluation variance?
It is a result of the Central Limit Theorem.
What is a positive or negative variance of a budget?
A variance is the difference between the projected budget and the actual performance for a particular account. A negative variance means that the budgeted amount was greater than the actual amount spent. A positive variance means that the budgeted amount was less than the actual amount spent. Note there is some debate over whether a negative variance means an underrun or an overrun. The Project Management Institute, however, endorses the accepted convention that a negative variance is a bad thing, and a positive variance a good thing.

What is adverse variance?
A non favourable variance Eg: adverse revenue means the company earned less revenue than expected.
What does it mean for a trait to have low variance?
A trait that has low variance suggests that there is a high environmental variance. This means that the success of a trait is increased if people are raised in optimal environmental conditions.
