QUESTIONS AND ANSWERS SURE A+
✔✔An example of a positive correlation would be based on which of the following
results? - ✔✔High levels of sedentary behavior during the day are related to higher
blood pressure.
✔✔Another way of saying we have found statistical significance would be to say -
✔✔these results are unlikely to be due to chance in the large majority of cases.
✔✔Rose has received IRB approval to conduct a study. She plans to recruit young
women to wear an activity tracker for one week and complete daily questionnaires. Prior
to enrolling a participant, what must Rose do? - ✔✔Rose must inform the participant of
the potential risks and benefits involved in participating in the study.
✔✔A professor is scoring her students' exams and realizes she was grading each
question on a scale from 0 to 3 instead of 1 to 4. If she makes this adjustment, which of
the following would be true? - ✔✔Only the mean will change, the standard deviation will
stay the same.
✔✔Which of the following is a description of a study using naturalistic observation
methods? - ✔✔going to a playground and taking notes on how boys and girls play
, ✔✔According to the textbook, the primary strength associated with using experimental
research method is that - ✔✔it allows control of variables and allow for the study of
causal relationships.
✔✔Experimental research is to correlational research as confounding variable is to -
✔✔third variable.
✔✔A researcher designs an experiment in which he is investigating the effects of
providing counselling versus medication for smoking cessation. In this study - ✔✔the
treatment group is the independent variable and smoking status is the dependent
variable.
✔✔In which of the following instances would you expect to have a perfect correlation
(correlation coefficient = +1.00)? - ✔✔the age of an older brother and the age of his
younger sister during their childhood
✔✔Alan wants to conduct a study to better children's peer interactions. In which of the
following scenarios would it be most appropriate to use correlational rather than causal
research methods? - ✔✔when studying children with down's syndrome compared to
their same-aged normally developing peers
✔✔A meta-analysis can be described as - ✔✔conducting a statistical analysis of
previously published results from different studies.
✔✔Rufus conducted a study in which he evaluated life satisfaction among patients with
a history of cancer. He found that the mean score was 21 out of 35, with a standard
deviation of 12 points. What does this large standard deviation tell us? - ✔✔Adults with
a history of cancer have a wide range of life satisfaction scores.
✔✔Hannah wants to better understand the learning and memory processes associated
with Alternating Hemiplegia of Childhood (AHA; a rare neurological condition). What
would be the best way for Hannah to gather her data? - ✔✔Find a single patient and his
family with AHA with whom to conduct in-depth interviews about their memory
processes.
✔✔Kevin is designing a study in which he asks participants to share their medical and
surgical history. It is possible that the participants' medical providers may receive
information about the participant's study results. Of the following, what is the best way
for Kevin to manage any concerns about privacy and confidentiality? - ✔✔Thoroughly
explain any potential risks to privacy and confidentiality to the participant during the
consent process.
