Chapter 6 Objectives , Questions, Hypothesis and Study Variables Flashcards
What are dead concepts at various levels of abstraction that are measured, manipulated, or controlled in a study
Study variables
What are clear, concise, declarative statemntents expressed in the present tense to specify the foci of the study
Research objectives/aims
What is a concise interrogative statement that is worked in the present tense and includes one or more of a study principles concepts or variables
Research questions
What is a stated relationship between or among variables within a specified population
Hypothesis
What type of hypothesis proposes a cause and effect relationship between variables in which one causes the other
A casual hypothesis
What type of hypothesis presents a noncauseative relationship among variables
Associative hypothesis
What type of hypothesis predicts the relationship between only two variables
Simple hypothesis
What type of hypothesis predicts the relationship among three of more variables
A complex hypothesis
What types of hypothesis states theatre or direction of a proposed relationship between variables
Directional hypothesis
What type of hypothesis does not specify the direction of the relationship between and among variables
Nondirectional hypothesis
What type of hypothesis is used for statistical testing and interpretation of study results
The null hypothesis AKA the statistical hypothesis
What type of hypothesis is the alternative hypothesis and it represents the researchers posited results
A research hypothesis
What types of hypothesis contains variables that can be precisely measured or manipulated in a study
Testable hypothesis
What are concepts or ideas qualities properties or characteristics of a person things or situations that are studied in research
Variables
What are variables that are subject or participant characteristics measured during a study and used to describe a sample
Demographic variables
What are variables that are not central to a study research purpose but have a potential effect on the results making the independent variable appear more or less powerful than it really is in its effect on the value of the dependent variable
Extraneous variables
What type of variables that are not recognized until the study is in process or that are recognized before the study is initiated but cannot be controlled
Confounding variables
What is the term for a variable that is used to refer to a variable that is the focus of a quantitative study but that is not identified as an independent or a dependent variable
Research variable
What type of variables are those that emanate from the research setting
Environmental variables
What type of variables change the strength and sometimes the direction of a relationship between other variables
Modifying variables
What type of variables that occur as links in the chan in between independent and dependent variables
Mediating variables
What identifies that meaning of an idea
A conceptual definition
What is the type of research that results in a measurement of the dependent or research variable
Operational defintion
