Which type of source summarizes information from sources of original research reports?

• Primary

• Secondary

• Premier

• Germinal

How do studies using experimental research differ from other types of research?

• Only experiments can demonstrate cause and effect relationships

• Only experiments can involve comparing two or more groups of scores

• Only experiments can describe the relationship between variables

• Only experiments can have more than one independent variable

For a within-subjects study comparing 2 treatments, A & B, a researcher expects that practice in the first treatment will improve the participants' scores in the 2nd treatment. If the order of treatments is counterbalanced, then the practice will __.

• influence scores in treatment A, but not B

• influence scores in treatment B, but not A

• influence scores in treatment A for half the participants & scores in B for half the participants

• not influence the scores in either treatment condition because the treatments are counterbalanced

In nonexperimental & quasi-experimental studies, different groups or conditions are defined in terms of __.

• independent variables

• dependent variables

• pre-existing participant variables or time

• treatment conditions

A potential drawback of secondary sources is that they….

• typically do not contain detailed information about any specific study

• often cover a decade or more of research in a given area

• provide detailed information about research methods, but little about results

• offer no statistical analysis in support of their conclusions

When it comes to comparison, researchers typically attempt to...

• increase the differences between treatments & decrease the variance within treatments

• decrease the differences between treatments & increase the variance within treatments

• increase the differences between treatments & increase the variance within treatments

• decrease the differences between treatments & decrease the variance within treatments

A researcher introduces a new math program in one school district & uses a neighboring district as a no-treatment control group. After the program is in place for 6months, the researcher intends to give the students in both districts a standardized math test & then compare their scores.  This research cannot be classified as a true experiment because ____.

• the treatment is only administered to one group

• the researcher does not control the assignment of participants to groups

• there is no pretest to determine mathematics ability before the program

• it is not conducted in a laboratory

A(n) _____ is a brief summary of a psychology article.

• abstract

• introduction

• key word summary

• running head

Which of the following bests demonstrates "compensatory equalization"?

• participants in the control group learn about the treatment & work harder to prove they can succeed in spite of not gaining the desired treatment

• participants in the treatment group resent having to work hard & demand they be placed in the control group

• participants in the control group learn about the treatment group & demand they get the same treatment

• participants in the treatment group accidentally "spread" their treatment to those in the control group

In an experiment, any variable that varies systematically with the treatment conditions & might influence participants’ sores is called a(n) ____ variable.

• matching

• dependent

• extraneous

• confounding
