Question:

In the article by Gadd and Phipps (2012), they refer to the challenges faced by psychological and, specifically, neuropsychological assessment. Their study focused on a preliminary standardisation of the Wisconsin Card Sorting Test (a non-verbal measure) for Setswana-speaking university students. The US normative sample is described as participants (N = 899) from both genders who were screened beforehand to exclude individuals with a history of neurological, learning, emotional and attention difficulties. The South African sample consisted of university students (N = 93) from both genders, between the ages of 18 and 29, who were screened in terms of hearing and visual impairments and any history of psychiatriceurological difficulties. The latter was done to prevent contamination of the results by these variables. The students were from the University of Limpopo, Medunsa Campus. Answer Questions 1 to 5.

Question 5

Gadd and Phipps (2012) found that the results of the South African sample on the Wisconsin Card Sorting Test did not resemble a normal distribution and could not be converted to a normal distribution. This implies that the ...

(1) mean performance of this sample cannot be calculated

(2) standard deviation will differ below and above the mean

(3) mean and standard deviation do not provide a predetermined distribution of performance

(4) results cannot be replicated

Would 1 be the correct answer?

Partial Question 5 0.5 / 1 pts Which of the following statements about Gauss's law are correct? (There may be more than one correct choice.) The electric flux passing through a Gaussian surface depends only on the amount of charge inside that surface, not on its size or shape. O Gauss's law is valid only for symmetric charge distributions, such as spheres and cylinders. V If a Gaussian surface is completely inside an electrostatic conductor, the electric field must always be zero at all points on that surface. If there is no charge inside of a Gaussian surface, the electric field must be zero at points of that surface. Only charge enclosed within a Gaussian surface can produce an electric field at points on that surface.[1] A Gaussian cube of edge length 1.0 m is located in the xyz space, as shown in the following figure. If the electric field in this space is expressed as: E = 4x ax + 3(yz + 3)ay V/m Determine: a) The electric flux through the top face of the Gaussian cube b) The net charge enclosed by the Gaussian cube Gaussian surface 1- 20m x- 30 mAssignment 4 Complete solution of Problem 1 and 2a using Naive Gaussian.
