Exam 2: Studying Behaviour Scientifically

In order to estimate the results in a local election,a pollster contacts a select group of people and asks them how they voted.The pollster is using which of the following research methods?

The independent variable is the variable administered to the experimental group and the dependent variable is the variable administered to the control group.

____________________ refers to the unintentional and subtle ways that the experimenters can influence and affect their participants to behave in a manner consistent with the experimental hypotheses.

Random assignment is important in experiments because:

Dr.Jun is conducting an experiment that has two experimental groups.In order to control for differences among her subjects,she flips a coin and uses chance to determine which subjects belong in which group.The procedure that Dr.Jun is using to place participants in the various groups is called:

The plus or minus sign (+/-)on the correlation coefficient reflects:

A major drawback of ____________ research is that unrepresentative samples can lead to inaccurate projections about how an entire population of people would respond.

Which of the following statements regarding the differences between experimental and correlational research is FALSE?

Dr.Johns found that as the temperature increased,his dogs romped around the yard less and less.This is an example of a(n)_____________ correlation.

Which of the following is an advantage of the case study method of research?

One of the major limitations of behavioural observations is that:

When the experimenter's subtle or unintentional behaviours influence the behaviour of participants in his/her experiment,the placebo effect occurs.
