Exam 2: Research Methods: Tools for Discovery

A small group of individuals can be the focus of a case study

If two variables are correlated +1.00:

An experiment in which researchers deliberately create a change in a real-world setting and then measure the outcome of their manipulation is called:

Hormones have a regulatory effect on the activity of certain organs

A form of observation in which researchers structure a situation so that behaviors they wish to study are more likely to occur is called:

Ecological validity refers to the degree to which a research study accurately represents events or processes that occur in the real world

An intervention:

Researchers interested in studying the way a child responds to a parent's directions would most likely use:

Focus groups are only valuable in the early stages of a study

In an ABAB design, the B represents:

To secure a child's participation in a study, it may be necessary to obtain informed consent from:

Correlational studies do not allow us to determine whether a factor is actually causing a child's behavior, yet researchers conduct them because:

Laboratory analogue experiments are not typically designed to address problems of artificiality

Natural experiments:

All research with human subjects requires that researchers obtain informed consent from participants before they are enrolled in the study

A principal difference between field experiments and interventions is that interventions have the explicit goal of changing behavior

An observer's tendency to be influenced by knowledge about the research design or hypothesis is:

An estimate of the magnitude of the difference between groups or the strength of the association between the factors is:

An effect size cannot represent the magnitude of the difference between treatment and control groups

A research sample in which participants are drawn from strata or categories in the same proportions as they are found in the larger population is:
