What else can I help you with?
How is variance of error term is derived?
Sse = ssr / ( n - k)
Score that is 15 above the means be an extreme score?
It depends entirely on the variance (or standard error).
Will a large sample size and a small sample variance produce the largest value for the estimated standard error?
no
What is subsampling in rcbd?
Each treatment is applied more than once per block. This makes it possible to enhance the error variance estimate by extracting some sampling variance from it. See the link for a visual example.
What difference between a favorable variance and an unfavorable variance?
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
Define error variance-?
The error in which a particular numbers are set apart is called error variance.
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.
How is variance of error term is derived?
Sse = ssr / ( n - k)
If the sample variance increases the estimated standard error will also increase?
true
Score that is 15 above the means be an extreme score?
It depends entirely on the variance (or standard error).
Will a large sample size and a small sample variance produce the largest value for the estimated standard error?
no
What shows you how accurate to the true value an experimental value is?
The error, which can be measured in a number of different ways. Error, percentage error, mean absolute deviation, standardised error, standard deviation, variance are some measures that can be used.
From a population with a variance of 900 a sample of 225 items is selected At 95 percent confidence the margin of error is?
3.92
What is heteroscedasticity and autocorrelation of the error term?
A sequence of variables in which each variable has a different variance. Heteroscedastics may be used to measure the margin of the error between predicted and actual data.
What is subsampling in rcbd?
Each treatment is applied more than once per block. This makes it possible to enhance the error variance estimate by extracting some sampling variance from it. See the link for a visual example.
Which of the following samples will produce the largest value for the estimated standard error?
A small sample size and a large sample variance.
What is the sample variance and the estimated standard error for a sample of n 4 scores with SS 300?
The sample variance is obtained by dividing SS by the degrees of freedom (n-1). In this case, the sample variance is SS/(n-1) = 300/(4-1) = 300/3 = 100 In order to get the standard error, you can do one of two things: a) divide the variance by n and get the square root of the result: square.root (100/4) = square.root(25) = 5, or b) get the standard deviation and divide it by the square root of n. 10/square.root(4) = 10/2 = 5
