Abstract:
Previous research suggests that the Victoria Symptom Validity Test (VSVT) is effective in confirming or disconfirming the validity of a patient's reported cognitive impairments. We sought to cross-validate the findings of the VSVT standardization study, and to determine cut-off scores that are most efficient in discriminating our samples of compensation-seeking patients, primarily with mild traumatic brain injury (CS; n = 53), and non-compensation seeking patients with intractable seizures (NCS; n = 30). All patients in the NCS sample scored in the "valid" range on the VSVT difficult memory items, compared to only 58.5% of the CS sample. We also identified VSVT measures and cut-off scores maximally efficient in discriminating these samples. This study confirms previous research that non-compensation seeking patients do well on the VSVT, but that many compensation seeking patients perform poorly on this measure.

01:19Testing 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...

Different sample means can result in different values for the variance estimate: variance between samples. This is because the variance between samples is calculated as the product of the sample size and the variance between the...
