1. FEEDBACK ON ASSIGNMENT 02
Question 1
What is the difference between the information provided in Table 3 and in Table 4 in the mini-
manual of the SBQ?
1) Table 3 shows the validity of the SBQ and Table 4 shows its reliability.
2) Both tables provide information about the validity of the SBQ.
3) Table 3 is about the SBQ’s internal inconsistency and Table 4 is about its test-retest
reliability.
4) Table 3 shows the reliability of the SBQ and Table 4 shows its validity.
Both tables provide information about the reliability of the SBQ. Table 3 shows the split-half
reliability. Split-half reliability is determined when you want to know to what extent all the items in
the questionnaire measures the same attribute (i.e. the internal consistency of the questionnaire).
To calculate this, the scores on two halves of the questionnaire are correlated. Table 4 shows the
test-retest reliability. Test-retest reliability is determined when you are interested in the
stability/consistency of the results over time, that is how consistent are the results over different
occasions. You administer the same questionnaire to the same group of people on two different
occasions. The two sets of scores are correlated.
QUESTION 2
What does Table 4 in the manual tell us about the reliability of the SBQ? Choose the most correct
answer.
1) The table shows that the SBQ was administered twice, and it indicates the total scores of
five respondents for each administration.
2) The table shows a poor correlation between the two sets of scores.
3) The table shows a poor correlation between the two sets of scores, and it is a negative
correlation.
4) The table shows a high correlation between the two sets of scores, implying that the
SBQ has test-retest reliability.
More than one of the answer options are true, but these options differ in terms of the value of the
information provided. The table shows that SBQ was administered twice, and it indicates the total
scores of five respondents for each administration. It will add value to consider the relationship
between the two sets of scores. We see that there is a high correlation between the two sets of
scores and it is a positive correlation (ascending values in the one set correspond with ascending
values in the other set). It adds even more value if we interpret this relationship in terms of the
reliability of the SBQ. The high correlation implies a high degree of test-retest reliability.
