Exam 2: Studying Behaviour Scientifically

In order to assess the effectiveness of a new statewide seatbelt law,researchers collected data from the Department of Transportation regarding the number of traffic fatalities in the last year.This type of measurement of behaviour is called a(n):

Imagine you have created a new personality questionnaire and you are worried about social desirability influencing people's responses.Which of the following would minimize the impact of this potential problem?

Dr.Sussman conducts a study on the effect of various motivational factors on job performance.In her study,she does an excellent job of controlling extraneous factors and as a result,we can have high confidence in the causal conclusions she draws.However,the participants in her study were from a select group of the population and,therefore,Dr.Sussman will be rather limited in terms of her ability to apply her results to other people and situations.Taken as a whole,this study would be said to have ________ internal validity and __________ external validity.

When a sample accurately reflects the important characteristics of the population from which it is drawn,it is said to be a(n)______________ sample.

In correlational research,the experimenter measures all of the variables and statistically determines whether there is an association between them.

A sample that accurately reflects the population from which it was taken is called a _______________ sample.

If you are conducting research that involves making observations of people's behaviour,one major issue that you would need to be concerned about is:

The technique typically used in experimental research to balance out differences between participants is called _____________ ______________.

The social desirability bias was discussed as a limitation of which of the major ways of measuring behaviour?

In experimental research,the researcher ______________ the independent variable and _________________ the dependent variable.

A statistic that indicates the strength and direction of a relation between two variables is called a(n)_____________________ coefficient.

The goal of meta-analysis is to

An operational definition defines a variable in terms of the specific procedures used to produce or measure it.

One of the primary techniques for reducing both the placebo effect and experimenter expectancy effects is random selection.

Examining the social behaviours of whales as they migrate is an example of

Which of the following would specifically be an advantage of the case study method of research? Case Studies:

Researchers must be particularly aware of the problem of social desirability when using ______________ measures to assess behaviour.

Which of the following would be a potential limitation of naturalistic observation?

One of the essential features of true experiments is that:

Which of the following is a major problem of after-the-fact or "hindsight" explanations?
