PLEASE HELP ME AND EXPLAIN WHY. THANK YOU.

In the same study, Gradidge and De Jager (2011) reported that no practically significant differences were found between the mean wellness of demographic groups (gender, language or academic year level). This is in line with wellness theory and previous research. Factor analysis also revealed the expected factor structure. Correlations between the seven subscales furthermore indicated that scales measure the same theoretical construct (i.e. Wellness). Answer Questions 11 to 15.

Question 11

The statistical methods described above, are ...

(a) discriminant validity

(b) theory-related group comparison

(c) correlations with other tests

(d) factorial validity

(e) convergent validity

(f) incremental validity

(1) (a) (b) (d)

(2) (b) (d) (e)

(3) (c) (d) (e)

(4) (c) (e) (f)

Question 12

The theoretical model of wellness employed here is relevant for a multicultural South African student population.

(1) true, the theoretical model was replicated across subgroups

(2) true, a new theoretical model was identified

(3) false, the underlying structure differed from the theoretical model

(4) false, the underlying structure differed between subgroups

Question 13

If a questionnaire of wellness correlates highly with a measure of depression while the correlation with a mechanical aptitude test is low, this implies that the wellness questionnaire shows ...

(1) high convergent but low discriminant validity

(2) low convergent but high discriminant validity

(3) high convergent and discriminant validity

(4) low convergent and discriminant validity

Question 14

Suppose that the researchers want to use the Wellness Questionnaire to determine if wellness is related to a person's level of satisfaction. They would need to determine the ... validity of the questionnaire.

(1) content

(2) construct

(3) predictive

(4) concurrent

Question 15

The 'level of satisfaction' referred to in Question 14 can be regarded as ...

(1) observable behaviour

(2) a cognitive construct

(3) an unknown

(4) a criterion
