Emphasizes on objective measurement and numerical analysis of data
Focuses on generalizing findings across groups of people
Has clearly defined research question to which objective answers are sought
Data is usually collected through structured research instruments
It can be replicated given its high reliability
Data is in a form of numbers and statistics
Use larger sample size based on representativeness of a population
It allows for .....
a broader study involving a larger number of samples for generalization of findings
greater objectivity and accuracy of findings
application of standard means for replication of study
minimizing personal bias
Static and rigid approach = inflexible process of discovery
Preset response does not necessarily reflect how people perceive about an issue or subject
Less elaborate accounts of human perception
May miss out contextual details
Quantitative research presumes to have an objective approach to study research problems where the data is controlled and measured in the process of accumulation of facts and determining causes of behaviors
What should you do before designing a quantitative research study?
Before designing a quantitative research, you should ...
Decide whether it will be descriptive or experimental in nature
It dictates how you collect, analyze and interpret the results of findings
A descriptive or non-intervention research is governed by the following principles ...
samples are generally measured once
the intention is to establish association between variables
use large sample size to ensure a valid estimate of a generalized relationship between variables has been obtained
What about intervention research design?
An intervention research design
It includes samples measured before and after a particular treatment
It can be categorized into two: experimental and quasi-experimental research
Samples may be small and purposefully chosen (depending on research problems)
It is intended to establish causality between variables
