11. when researchers use multiple items to measure a single concept, they hope for high levels of consistent responses on these items. (High Cronbach's Alpha) If they achieve this sort of interr consistence, they have achieved:
o Construct validity
o Criterion validity
o Inter-observer reliability
o Test-Retest reliability
o Content validity
12. As the size of the sample goes up,
o The fraction of the total population that a sample contains decreases o Its proportion to the size of the population must remain constant
o The confidence intervals of sample statistics increase
o Confidence in its representativeness of the population decreases
o Confidence in its representativeness of the population increases

(10)
It is an example of negative association.
