Inductive vs. Deductive Reasoning
|
Deductive: general to specificInductive: specific to general
|
Theoretical Framework vs. Conceptual Framework (differences between)
|
Theoretical Framework: already exists in literature as a mid range theory that has been tested (eg-Orem's or Neumans); serves as a foundation of the studyConceptual framework: researcher devises for that particular study
|
Hypothesis: What are characteristics of a workable hypothesis?
|
-Concise, conjectural statement-1 relationship is expressed per hypothesis (studies may have more than one hypothesis)-usually written in a declarative sentence form-written prior to the start of the study in a quantitative design-an Identified population-"goes with" (follows from) the problem and purpose-Is testable- has 1 Independent variable and 1 dependent variable and they are measurable
|
What is the purpose of the Hypothesis?
|
-Statement that makes a prediciton about an expected outcome-translates purpose statment into prediction of expected results that can be measured-"sets the stage" for study design
|
Name 4 types of hypotheses
|
-Associative or Causative-Simple or Complex-Directional or Non-Directional-Statistical (Null) or Research
|
What is an Associative vs Causative hypothesis?
|
Causal: variable A causes variable BAssociative: relationship between varible A and B so if one changes, then the other chnages in a predictable way BUT are NOT saying they change because variable A causes B or vice versa (uses words like "caused by" or "causes.")
|
What is a Simple vs Complex hypothesis?
|
Simple: predicts a relationship between 2 variables Complex: Predicts a relationship between 3 or more variables
|
What is a Directional or Non Directional hypothesis?
|
-Directional: states nature of the interaction (uses words like More, Less, Greater, Lower, Increase, Decrease)
-Positive Relationship: prediction that variables change in the same direction -Negative Relationship: prediction that variables change in opposite directions -NON-direction: says that a relationship exists but does not predict the nature of the relationship (uses phrase "Is related to" without any qualifiers) |
In this hypothesis: Identify Type, Independent Variable; Dependent variable
|
X
|
In a directional hypothesis: What is a positive relationship? What is a negative Hypothesis?
|
Positive: variables change in the same directionNegative: variables change in the opposite direction
|
Independent vs Dependent Variables
|
J
|
What are Research Variables?
|
Research Variables -Are part of the research question (instead of IV or DV that are in hypotheses)-Those characteristics that are mentioned in purpose and observed or measured-observed in natural setting-Terminology used by qualitative studies and descriptive and correlational (quantitative) designs
|
Distinguish how extraneous variables can be a source of bias
|
-are other variables that can possibly affect the results of the study-best to recognize them but may not be obvious-try to control if you can -in quasi-experimental and experimental - acknowledge and control them
|
Explain how demographics are variables
|
Height, age, race, weight, gender. If they are varying in the groups - these may be factors that influence subject responses/data and can influence the outcome rather than the just the independent variable
|
How to determine if a variable is operational or conceptual
|
Conceptual: theoretical meaning and usually very abstract
Operational: defines variable so that it can be MEASURED. makes variable empirical |
