SECTION 1.2
EXERCISE SET 1
1.1: This is an observational study because the person conducting the study merely recorded (based
on a survey) whether or not the respondents believe it is “very important” for couples who have who
have children together to be married.
1.2: This is an observational study because the researchers analyzed data from hospital emergency
departments. No older people were assigned “walking dog” or “not walking dog” treatments.
1.3: This is an experiment because the researchers assigned different toddlers to experimental
conditions (adult played with/talked to the robot or the adult ignored the robot).
1
, 1.4: This is an observational study because the researchers surveyed U.S. adults and drew a
conclusion from the survey results; there were no experimental treatments assigned.
1.5: This is an experiment because the researchers assigned study participants to one of three
treatment groups (meditation, distraction task, or relaxation technique).
EXERCISE SET 2
1.6: This is an observational study based on results of a survey (no consumers were assigned to
different experimental conditions).
1.7: This is an experiment because the participants (diners at full-service restaurants on a college
campus) were assigned to different experimental conditions (usual menus or menus with the addition of
calorie labels).
1.8: This is an observational study because the researchers collected data using a survey about
“cancel culture” and had the respondents explain the term. There was no assignment to different
experimental conditions.
1.9: This is an experiment because the researchers assigned study participants to different
experimental conditions (garlic supplement group or no garlic supplement group).
1.10: This is an experiment because the researchers assigned the children to different experimental
groups (ball behaving as expected and ball behaving in an unexpected way).
ADDITIONAL EXERCISES FOR SECTION 1.2
1.11: This is an observational study because the researchers observed the proportion of patients who
got an infection in the two groups (overnight hospitalization or more than one night hospitalization);
there was no assignment of subjects to experimental groups.
1.12: This is an experiment because the course professor assigned each discussion group an instructor
who taught under a particular gender identity (perceived gender was the experimental treatment).
1.13: This is an experiment because the study participants were assigned to one of the two
experimental groups (how much would you pay for the mug or how much would you sell the mug for).
1.14: The study described was an experiment because the study participants were asked either the
first or second question (the participants were assigned to one of the two experimental groups).
SECTION 1.3
EXERCISE SET 1
1.15: (a) The group of 857 bicycle fatalities represents a census of the 2018 bicycle fatalities. (b)
Because the group of 857 represents a census, the average age of 47 years is a population characteristic.
1.16: The sample is the 100 San Fernando Valley residents, and the population of interest is all San
Fernando Valley residents.
