MIDTERM EXAM: PRACTICAL RESEARCH 2

Mixed-method research refers to use of both:

• A) Experimental and correlational methods

• B) Quantitative and qualitative methods

• C) Description and intervention

• D) Group and single subject designs

Which of the following factors should NOT influence the decision when one is selecting a topic or problem for research?

• A) Will solution of the problem advance knowledge in my field?

• B) Will I be able to prove that my previously held beliefs are true?

• C) Will the study lead to the development of other investigations?

• D) Is the topic or problem amenable to research?

Operational definitions are encouraged in research in order to:

• A) conform to the requirement of statistical analysis

• B) increase the probability that experiments will succeed

• C) make terms used in a study as explicit as possible

• D) make educational research more easily understood by laypersons

"Students taught first aid by programmed instruction will achieve at a higher level than those taught first aid by the traditional method." The independent variable in this hypothesis is:

• A) students

• B) level of achievement

• C) programmed instruction

• D) method of instruction

"Students taught first aid by programmed instruction will achieve at a higher level than those taught first aid by the traditional method." In the example in question 9, the dependent variable is:

• A) students

• B) level of achievement

• C) programmed instruction

• D) method of instruction

Statements or predictions that are tested by collecting and analyzing objective evidence are called:

• A) assumptions

• B) indicators

• C) hypotheses

• D) premises

A research report states that Group A was exposed to a new teaching method and Group B was exposed to a traditional method. At the end of a four-month period, each group was given the same achievement test. Group A had a mean score that was higher than the mean score for Group B. The dependent variable in this study was the:

• A) achievement scores of the students

• B) motivation of the students

• C) type of teaching

• D) length of the period of instruction

The dependent variable is so called because:

• A) scores on this variable are hypothesized to depend on, and vary with, the value of the independent variable

• B) the outcome of an experiment is hypothesized to depend on the effect that this variable has on the independent variable

• C) scores on this variable can be expected not to vary in an experiment

• D) scores on this variable depend on how they are manipulated by the researcher

A researcher who decides to deceive participants in a study should:

• A) determine that the study cannot be done without deception

• B) argue convincingly that the importance of the study justifies deception

• C) undeceive participants as soon as possible

• D) all of the above

Informed consent to serve as a subject in research requires signing a document that states:

• A) the purpose of the study

• B) that the subject may end participation at any time

• C) the probable risks involved

• D) all of the above
