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
The first step in selecting a sample should be to:
A) define the population
B) decide how to stratify the population
C) compile a list of the population
D) determine how to randomize
A research worker plans to evaluate high school students' reactions to a new policy on closed campus stations. He locates himself near the office of the dean, where he interviews every fourth student who visits the dean. He eventually secures data from 100 interviews and publishes his findings as the "Reactions of high school students to a new policy for a closed campus." What may be wrong with this approach?
A) Too small a sample
B) Inadequately defined problem
C) Inadequate techniques of analysis
D) Biased sample
The most important consideration in selecting a sample is that the sample be:
A) selected from the population by means of a table of random numbers
B) made up of a large number of subjects
C) representative of the population
D) selected from a large number of individuals or elements
Which of the following is the best synonym for validity?
A) Consistency
B) Feasibility
C) Truthfulness
D) Economy
Which of the following is the best synonym for reliability?
A) Consistency
B) Usefulness
C) Truthfulness
D) Economy

Directions: Select two of the three questions below and provide an answer in a paragraph or so in the space provided. Each response is worth 10 points.
1. An educational researcher is interested in the relationship between students’ participation in two after school programs and academic achievement. She states the following hypothesis in the description of her study:
H.1. Children who participate in an after school program that emphasizes critical thinking skills will score higher on measures of academic achievement and self esteem than students who participate in a program that emphasizes rote memorization.
1.What are the variables in this study? 2. Identify the independent variable(s) and dependent variable(s). Describe how each variable varies (i.e., whether the variable is categorical or continuous). 3. Provide justification for why each variable varies the way you describe?
