A special program was run to improve the goal-shooting accuracy of the school's basketballers. A study of the effectiveness of the program was undertaken to determine if it should be used in other schools.
A trial is run before the program is implemented and the average score for the shooters is 52%. The shooters are then randomly divided into two groups. The members of the control group practise shooting for one hour per day, under the supervision of their classroom teacher. The members of the experimental group undertake the special program for one hour per day, under the supervision of their basketball coach. After five sessions, the test is repeated and the scores recorded.
A potential confounding variable in this study is
A.the classroom teacher versus the expertise of basketball coach.
B.the health of the basketball players before and after the program.
C.the height of the basketball players.
D.the age of each basketballer, and therefore the average age of the group to which they are assigned.
In an experiment, debriefing of participants most likely includes information about
A.each participant’s own results in the study.
B.the number of hours participants will be expected to participate.
C.the procedures that will be required of participants during the experiment.
D.the individual results of other participants in the study.
The main purpose of ethical guidelines for research in Psychology is to
A.minimise the problems that participants cause for researchers.
B.guarantee that the experimentation runs without problems.
C.ensure that any results published will not be challenged.
D.protect the welfare and rights of the participants.
In a study, injections of saline solution (which contains no chemicals) were shown to be quite effective for relieving pain. This is an example of
A.an experimenter effect.
B.a placebo effect.
C.the experimental effect.
D.an order effect.

What is the term referred to the extent to which the researcher is testing what they claim to be testing ?
Validity
Reliability
Generalisability
An experimental design in which different participants are used in each level of IV
Repeated measures design

Matched pairs design
Reliability is the extent to which a procedure is consistent to produce the same results with same people on each occasion.
True
False

Positive correlation
Negative correlation
