valid

which of the following is most important to an evaluator: reliability, objectivity, validity?

validity

what are the elements of the participant, instrumentation, procedures, and design and analysis section of the introduction?

References to journal articles should include

Author, date, article title, journal total, volume Number, issue number, page numbers (look in book for answer)

identify which sources would make a good beginning point in a literature search

Encyclopedias, textbooks and literature reviews

The only type of research that can manipulate treatment and establish a cause and effect is

Experimental research

external validity

The generalizability of the results of a study. To what extent can the results apply to the real world?

a researcher predicts that there will be no significant relationship between attitude scores and grade point average. This is an example of what?

a null hypothesis

what is empirical research

a study based on objective; collects data in which to base decisions

when a person concludes that there is a difference between populations means when she has actually observed an improbable difference between two sample means that come from identical populations, she has made what type of error?

a type 1 error

the probability that a specific result will occur strictly as a result of chance is called what

alpha level

randomly assigned subjects to treatments or exposures is known as

classic controlled experiment

a thesis was submitted with the title "a study comparing the achievement of 6th grade students in moscow, idaho, instructed in health education through closed-circuit television and regular classroom procedure for a period of 16 weeks." this title

in which part of the methods section should you expect to find information about when the participants were tested?

procedures

identify elements of both a research hypothesis, and, more importantly, a null hypothesis

research hypothesis- null hypothesis-

when a researcher rejects H0 when H0 is false, she has made what type of error?

she made the right decision

at the end of a well-written introduction, the reader should be able to predict what?

the statement of the problem (purpose of study).

internal validity

The extent to which the results of a study can be attributed to the treatments used in the study. internal validity refers to the extent to which the results can be attributed to the treatments used in the study. In other words, the researcher must try to control all other variables that could influence the results.

the part of the methods section of the research paper that describes the activities of each treatment group is titled

procedures

researchers set small alpha levels (eg: alpha = .05) because they want to avoid what type of errors?

rejecting the null hypothesis when it's true
