PR 2 (LESSON 2) - KINDS OF QUANTITATIVE RESEARCH DESIGN

Creswell, 2013

Research is a systematic and objective creation of knowledge

RESEARCH DESIGN

framework of research methods and techniques chosen by a researcher

DATA COLLECTION, DATA ANALYSIS, AND REPORT WRITING

specific procedures involved in the research process

RESEARCH PROBLEM

determines the type of design you should use

DESCRIPTIVE AND EXPERIMENTAL

two main types of quantitative research design

SURVEY (DESCRIPTIVE)

very old technique but still the most used non-experimental research in the field of social sciences

intends to provide numeric description of trends, attitudes, or opinions of a population by studying a sample of that population

CROSS-SECTIONAL SURVEY

it is being conducted if the information collected from sample is from a single point in time but respondents come from different groups.

LONGITUDINAL SURVEY

it is being conducted if the information collected from a sample if over a period of time, sometimes lasting many years in order to study the changes through the years from the same respondents.

EVALUATIVE (DESCRIPTIVE)

refers to the study on the efficiency or effectiveness of policies, instruments, or the variables being considered.

elicits feedback to aid in decision making or policy information

DEVELOPMENTAL (DESCRIPTIVE)

systematic study of designing, developing, and evaluating instructional programs, processes, and products that meet criteria of internal consistency and effectiveness

particularly important in the field of instructional technology

EVALUATIVE (DESCRIPTIVE)

refers to the study on the efficiency or effectiveness of policies, instruments, or the variables being considered

elicits feedback to aid in decision making or policy formation

CORRELATIONAL (DESCRIPTIVE)

examines the relationship between two or more variables (predictor and criterion variables)

correlation does not mean causation

CORRELATION COEFFICIENT

measures the strength of relationship between variables

CAUSAL-COMPARATIVE

seeks to find the relationships between independent and dependent variables after an action or event has already occurred

compared two or more groups to find out whether the independent variable affected the outcome or the dependent variable

the independent variable cannot be manipulated

TRUE EXPERIMENTAL

may be carried out with or without a pre-test

uses random selection in determining the participants of experimental group or control group

most accurate type of experimental design

QUASI-EXPERIMENTAL

bearing resemblance to the true-experimental research

the participants are not randomly assigned

fails to qualify as a genuine experimental research

QUASI

means partial, half, or pseudo
