What is the variance for the uniform random variable?
the variance of the uniform distribution is (a+b)/12
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 does homogeneity of variance mean?
It means that the variance remains the same across the range of values of the variable.
What is concomitant variance?
Concomitant variance refers to the situation where the variability of one variable is related to the variability of another variable. It indicates that as one variable changes, the degree of variability in another variable also changes, suggesting a potential relationship between the two. This concept is often used in statistics and research to understand how different factors may influence each other's variability. Understanding concomitant variance can help in identifying interactions in data and improving model predictions.
What is the moment generating function for normal distribution with mean 20 and variance 25?
It is exp(20t + 25/2*t^2).
What are the properties of z in a normal distribution?
Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.
What is the difference between variable overheads cost variance andfixed overheads cost variance?
Variable overhead cost variance is that variance which is in variable overheads costs between the standard cost and the actual variable cost WHILE fixed overheads cost variance is variance between standard fixed overhead cost and actual fixed overhead cost.
What are the variances in a 4 variance analysis?
efficiency variance, spending variance, production volume variance, variable and fixed components
What is the variance for the uniform random variable?
the variance of the uniform distribution is (a+b)/12

How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
What does homogeneity of variance mean?
It means that the variance remains the same across the range of values of the variable.
What is Proportion of variance unaccounted?
The unaccounted for variance aka Error Variance, is the amount of variance of the dependent variable (DV) that is not accounted for by the main effects/independent variables (IV) and their interactions.
What is the difference between the coefficient of simple determination and that of multiple determination?
The coefficient of simple determination tells the proportion of variance in one variable that can be accounted for (or explained) by variance in another variable. The coefficient of multiple determination is the Proportion of variance X and Y share with Z; or proportion of variance in Z that can be explained by X & Y.
What causes variance in the criterion variable?
Let me guess...stats comps, too?
The mean of the discrete random variable X is 18.59 What is the variance of X?
23.18
In analysis of variance the term factor refers to?
independent or quasi-independent variable
