Term
What are the steps in the Research Process?
Definition
  • Select a topic
  • Narrow down to research question
  • Review the literature (theory and past research)
  • Develop a hypothesis or hypotheses
  • Design a study
  • Collect data
  • Analyze Data
  • Interpret data
  • Inform Others
Term
The research is not a ____ process
Definition

Linear


-we revisit certain steps throughout the research process

Term

Role of Theoretical Perspective



Different approaches

 

(falls out of scientific approach)

Definition
  • Positivist approach - reality consists of objective facts
  • Interpretative approach - realities are constructed [everyone has their own social reality]
  • Critical Approach - intersection of objective and constructionist view of reality  [ there might be an objective reality but it's been distored (e.g, political studies, feminism things)]
Term
What is the Role of theory?
Definition

It organizes and explains a variety of specific facts or descriptions of behaviour

 

-a framework for making these facts and descriptions comprehensible

Term

The Role of Theory

 

 

What are the two approaches?

Definition
  • Deductive approach - testing theories with data
  • Inductive approach - use data to build theory (e.g., grounded theory)
Term
What makes a Good Theory?
Definition
  • Testability and specificty
  • Internal consistency and clarity
  • Empirical Support
  • Parsimony
  • Scientific Impact
Term

What Makes a Good Theory?


Testability and specificity definition:

Definition

-Must be empirically testable

-Must allow us to make predictions that are specific

Term

What Makes a Good Theory?



Internal consistency and Clarity Definition

Definition

 - Principles should NOT contradict one another, does not not make condradictory redictions about the outcomes that will occur in a particular situation 

 

-Concepts and links between them should be clearly specified

Term

What Makes a Good Theory?




Empirical Support Description

Definition

 

-Must be consistent with the known empirical facts @ that time

 

-Cannot rest on the laurels of preexisting evidence

Term

What makes a Good Theory?




Law of Parsimony

Definition
-Explanations should use the minimum number of principles necessary to account for the greatest number of facts
Term

What Makes a Good Theory?




Scientific Impact description 

Definition

 

-Should stimulate research and contribute to the advancement of scientific knowledge

Term

Proof and Disproof



It is always possible that our results are due to _______

Definition

Chance


-A single set of results cannot disprove a hypothesis derived from a theory 

Term

 

 

Inductive Reasoning

Definition

-Specific to general

-Data to theory 

-Data driven "bottom up" 

-e.g. medical diagnosis based on symptoms

 

-used for generating hypotheses 

Term
We can use inductive reasoning to make _____________ about a population of interest based on the statistical analyses run on the specific sample we used to test our hypotheses about a population (but these hypotheses are developed using deductive reasoning)
Definition
Generalizations
Term

 

 

Deductive Reasoning:

Definition

-General to specific

-Theory to data 

-Theory driven "top down" 

 

-E.g., all people have a _____. Pat is a person, therefore Pat has a ______

 

Term

Deductive Reasoning:

 

In adpoting the scientific method, researchers are more likely to use Deductive reasoning to develop a _________

Definition
Hypotheses
Term

Logic and Inference




Falsification

Definition

-Karl Popper's description of how science is performed 

 

-Science should be concerned with Disproving theories through logic based on observation 

Term
Quantitative Research:
Definition

-NUMERICAL data 

-Statistical analysis

Term
Qualitiative Research
Definition

-hollistic or thematic description & understanding of behaviour

 

-Primarily nonstatistical analysis of data

Term

Purpose of Conducting Research



the 3 different kinds of research

 

Definition
  • Exploratory
  • Descriptive
  • Explanatory 
Term

Puprose of Conducting Research



Exploratory Research

Definition

-Little is known of the topic or minimal research has examined the topic

-Asks "what"

-Rich qualitiative data [documenting in words]

Term

Purpose of Conducting Research



Descriptive Research

Definition

-Have ideas about a topic but need to describe it

-Asks "how?" "where?" "who?"

 

Can inclute observational, correlational research - describing relationships we are seeing and maybe even consequences - are there identified patterns we can elaborat on? How does it fit in with other events?

Term

Puprose of Conducting Research


Explanatory Research

Definition

-Lack an understanding of the sources of a particular phenomenon 

-Asks "why?" 

 

-Causal relationships, getting at the why - not always ethical or practical

Term

Operational Definition

Definition

-Definition of CRUCIAL terms in the hypothesis in reference to concrete operations 

Term

 

 

Two types of operational definitions:

Definition

-Measured: may specify both how observations are to be made and what is to be observed and measured 

 

-Experimental: describes how experimental procedures are to be followed

Term

Variables 



definition

Definition
-any attribute or property in which organisms (objects, events, people) vary.
Term

Variables



examples of variables:

Definition
-Age, sex, weight, mental ability, relgious affiliation, aggression
Term
To qualify as a variable, the attribute or property under examination must consist of at least _____ ________
Definition
TWO values (e.g., male and female)
Term
At any given time, it must be possible to assign each element in the population ____ and ____ _____ ______ on the variable under consideration
Definition

One

and ONLY one value

 

(e.g. =, male OR female - you can never be both or neither)

Term
Independent Variable
Definition
-Systematically manipulated by the researcher in experimental research
Term
Dependent Variable 
Definition
-outcome of interest; what we design research to assess / measure
Term

-Laboratory settings offer researchers ________

-Field settings offer researchers a "____-_____" context 

 

-Field experiments still entail _____________ of an IV, but occur in a ______ setting as apposed to a ___ setting

Definition

-Control 

-"real - world"

 

-Manipulation

-Natural

-lab

Term
Internal Validity 
Definition

-Represents the degree to which we can confidently infer that our study demo'd that one variable had a causal effect on another variable 

 

 

Term
Internal Validity is compromised by:
Definition

The presence of confounds

(extraneous variables that systematically vary along with the variables we are studying and therefor provide potential alternative explanations for our results.)

Term
External Validity
Definition

Concerns inferences about the generalizability of the findings beyond the circumstances of the present study.

 

 

(application)

Term
Four ways to ensure high quality research:
Definition
  • Through impartial, sytematic observation using logically sound research design
  • Through Statistical description and inference 
  • Through reason and logic
  • By emphasizing perspective and context
