1) In a multi-group study what is the best way to distribute participants to the groups? a) selectively b) planned order c) randomly d) every other 2) In a two group treatment study, if I'm worried about validity of results of an outcome measure what should I do? a) Blind the participants to which group they are in b) Blind the person giving the outcome measure to the hypothesis c) blind the person giving the outcome measure to what group participants are in  d) Blind the caregivers 3) If I am comparing results of two treatment groups what is the correct statistical test of significance? a) ANOVA b) correlation c) t-test d) regression 4) A researcher predicts that the 3 days a week treatment group will improve more than the 2 days a week treatment group. What type of prediction is this? a) alternative non-directional hypothesis b) null hypothesis c) rationale d) alternative directional hypothesis 5) A research wants to ensure that outcome measure scoring across participants is consistent. What should she add to her study procedures? a) face and content validity b) control measures c) inter-rater and intra-rater reliability d) inclusion/exclusion criteria 6) A researcher is trying to decide what design to use for her study. Her study will be a phase 2 study in which she is developing a treatment protocol. Which design is most appropriate? a) single-subject design b) meta-analysis c) descriptive design d) case design 7) What is the control in a study in which one treatment group receives a new experimental treatment and the other group receives a current clinical treatment? a) experimental treatment b) there is no control c) time d) current clinical treatment 8) What are the independent and dependent variables in study examining the effects of severity of disorder on treatment outcomes? a) IV: treatment outcomes, DV: severity b) IV: severity, DV: treatment outcomes c) IV: treatment outcomes, DV: test scores d) IV: severity, DV: test scores 9) What is the outcome measure of a study examining the effect of DTTC on articulation measured by Goldman-Fristoe scores? a) DTTC b) treatment c) Goldman-Fristoe d) Goldman-Fristoe scores 10) A research incorrectly concluded the treatment was effective. What error has she made? a) Type A b) Type I c) Type B d) Type II 11) The results of a study are: 2 days a week treatment vs 3 days week treatment, p ≤ .05 in which the mean for 3 days a week is higher than 2 days a week; 2 days a week vs no treatment p ≤ .05 in which the mean for 2 days a week is higher than no treatment; 3 days a week vs no treamtent, p ≤ .05 in which the mean for 3 days a week is higher than no treatment. What are does this mean? a) 3 days a week is better than 2 days and no treatment; but 2 days is not better than no treatment b) 3 days a week is better than 2 days and no treatment; 2 days is better than no treatment c) 3 days a week is not better than 2 days a week but is better than no treatment d) 3 days a week and 2 days are week are no better than no treament
