At this smaller y-axis range, the high chloroform washing sample variance is detectable via the significantly higher error bars compared with white light interferometry.
For k = 1 we get the sample variance (46) and the sample covariance (50) (for i = 1, 2, ..., p) from the first row of the sample covariance matrix of variables [B.sup.(1)], [B.sup.(2)], ..., [B.sup.(p)] making use of the relative weights [w.sup.(1).sub.i*].
As indicated, the significant changes for pre- and postleveling mean values of BD, pH, FC, PWP, and WHC for the surface soil according to the paired t-test (Table 1), the sample variance (<r) values of, same properties except PWP, were also significantly affected (P [less than or equal to] 0.05) by the land leveling (Table 2) according to the Levene's test.
The weighted least squares fit of the model expressed in equation 1 gives us the result that appears in equation 2, where the only predictor is the sample variance, and Y' represents the prediction made by the model for the Log(l-[alpha]), as expressed in Equation 1.
The calculation of complex sample variances is supported by commonly used statistical packages (see, for example, SAS 2009; SPSS 2009; Stata 2009; Westat 2009).
(13) When we take a sample variance under the Gaussian assumption, we consider it as an estimate of the unknown population variance.
Regarding the coverage probabilities for the Wilson intervals, Chebyshev's inequality guarantees a minimum coverage of (1 - 1/[Z.sub.[alpha]/2.sup.2]) for the Wilson intervals since the population variance, not the sample variance, is used in the calculation.
it is just to adjust the size of the sample variance. Before you go back to William's message, look over Ed's (# 488) where he mentions estimation and then Deanne's (# 437) where she has the sentence that may come closest to the true reason we use n-1 ...

(10) Specifically, for each month during this period, I calculate the sample variance of returns over the previous 36 months.
The Modulus Uncertainty Calculator also allows you to reduce the test variance, prior to running samples, so you can examine your sample variance with more confidence.
