factorial validity

Question 1

what is factorial validity?

Answer 1

is relevant to determining whether the scores of a measure correspond to the number and nature of dimensions of theorised dimensions that underlie the construct of interest

Question 2

what does factor analysis do?

Answer 2

helps to determine the number and nature of dimensions associated with the scores derived from a test

Question 3

what does factorial validity pertian to?

Answer 3

the internal structure of test scores which is the way the parts of a test are related to eachother

Question 4

what are the three things factor analysis does?

Answer 4

• clarify number of factors
• determine the nature of associations
• determine which items are linked to which ffactor

Question 5

what is a unidimensional test?

Answer 5

consists of items which all measure one factor

Question 6

what is a multidimensional uncorrelated test?

Answer 6

items which measure two or more dimensions that arent related to eachother

Question 7

what is multi correlated?

Answer 7

two or more that are correlated with eachother

Question 8

what are the three different types of test?

Answer 8

unidimensional, multi dimensional uncorrelated, multi correlated

Question 9

for unidimensional tests, what does FA do?

Answer 9

can estimate the degree to which each indicator is linked to the attribute

Question 10

what does test dimensionality have implications for?

Answer 10

scoring, evaluation and test scores

Question 11

what is the psychological meaning of dimensions and how is it found?

Answer 11

accomplished by evaluating which items load onto each respective dimensions and done through CA or FA
