Question

-It would not be appropriate to use the Mann–Whitney U test when:

a researcher is comparing two independent populations.

the dependent variable is measured at the ordinal level.

the assumptions for an independent-samples t test are not met.

a researcher is comparing three or more groups on a normally distributed dependent variable.

-Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables. Kia is using a(n):

correlational design

experimental design

quasi-experimental design

descriptive design

-If a researcher randomly assigns participants to one of two conditions, that researcher is likely to use a(n):

descriptive design

correlational design

quasi-experimental design

experimental design

-Quasi-experimental designs classify cases by:

using the naturally occurring status of participants.

manipulating independent variables of interest.

manipulating dependent variables of interest

using random assignment

Answer 1
