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 error variance?

Is the result of unsystematic differences among participants; that portion of the total variance in a set of data that remains unaccounted for a systematic variance is removed; variance that is unrelated to the variables under investigation in a study.

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.


What is the sample variance and the estimated standard error for a sample of n 9 and scores with SS 72?

The sample variance (s²) is calculated using the formula ( s² = \frac{SS}{n - 1} ), where SS is the sum of squares and n is the sample size. For a sample size of n = 9 and SS = 72, the sample variance is ( s² = \frac{72}{9 - 1} = \frac{72}{8} = 9 ). The estimated standard error (SE) is the square root of the sample variance divided by the sample size, calculated as ( SE = \sqrt{\frac{s²}{n}} = \sqrt{\frac{9}{9}} = 1 ). Thus, the sample variance is 9 and the estimated standard error is 1.

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?
