Based on previous research on conditional reliability for number-correct test scores, conditioned on levels of the logit scale in item response theory, this article deals with conditional reliability of classical-type weighted scores conditioned on latent levels of a bounded scale. This is done in the framework of the D-scoring method of measurement (D-scale, bounded from 0 to 1). Along with the conditional reliability of weighted D-scores, conditioned on latent levels of the D-scale, presented are some additional measures of precision-conditional standard error, conditional signal-to-noise ratio, and marginal reliability. A syntax code (in R) for all computations is also provided.

Testing a Claim about Standard Deviation
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...

Coefficient of Correlation
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...
