If a set of data has 100 points and a variance 4 then what is the standard deviation?
Standard deviation is the square root of the variance. Since you stated the variance is 4, the standard deviation is 2.
What is the variance of the data set of 18 14 10 9 5?
- 4
What is F-ratio?
The F-ratio is a statistical ratio which arises as the ratio of two chi-square distributions.If X and Y are two random variables which are independent and approximately normally distributed, then their variances have chi-squared distributions. The ration of these chi-square distributions, appropriately scaled, is called the F-ratio.The F-ratio is used extensively in analysis of variance to determine what proportion of the variation in the dependent variable is explained by an explanatory variable (and the model being tested).
What is the variance of the scores 2 6 1 4 2 2 4 3 2?
2.12.12.12.1
Which is not a measure of dispersion range or variance?
Variance
In an analysis of variance is SS directly influenced by the size of the sample variances?
Yes it is.
In an analysis of variance which is directly influenced by the size of the sample variances?
df within
What are adverse variances?
Adverse variances means unfavourable variance which is actual expenses are more than budgted variance.
Basic assumption in analysis of variance?
1- observations are from normally distributed populations. 2- observations are from populations with equal variances.
What is the F stat in regression analysis?
The F stat tests the equality of variances. It uses statistical tables for reference and is calculated with F = Variance 1 (max)/variance 2(min).
Why are variances generally segregated in terms of a price variance and an efficiency variance?
Efficiency Varian materials and direct labor, the variances were recorded in specific general ledger accounts.
What factors causes Budget Variance?
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
What is the meaning of analysis of covariance?
A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
Can additive variance have a negative value?
No. Variance is always positive and so the sum of variances must also be positive.
