Q1 WEEK 3? Flashcards
It is a question or a matter involving doubt, uncertainty, difficulty that is proposed for a solution or discussion.
Research Problem
by looking at the research title, you should be able to gest the research problem right away
2 Types of Research Question
Descriptive and Inferential
Typically asks the “what is…?” with the underlying purpose of describing a situation, state or existence of a specific variable.
Descriptive Research Question
describes and that’s it…
in quantitative research is usually numerical
Suggest a relationship of difference of some sort between two or more variables to be investigated
Inferential Research Question
In a normal quantitative research statement of the problem, the design of questions 1-3 are:
- D
- D
- I
Elements of Research Problem
Specific -
Measurable - all variables should be numerically possible to measure
Attainable - consider your resources and skill sets
Relevant - should be timely (e.g covid)
Time-oriented
-
Anything we measure through numbers in quantitative research
Research variable
Anything that has quantity and that varies.
Research Variable
Basic units of the information studied and interpreted in research.
Research Variable
May be manipulated and measured to test cause-and-effect relationship.
Research Variable
Two Types of Research Variables
Independent Variable
Depedent Variable
Say something about the Independent Variable
_Also known as “predicator variable” or explanatory variable —through it we can predict the result
_purposefully changed to see how other variables will respond
_Variable that the researcher controls or manipulates within the study
Say something about dependent variable
Also known as “response variable” or “outcome” variable
because it responds to the changes made in the Independent Variable
the one being measured in a study reflecting an outcome.
Do not directly control this variable
Variable that is being observed under different circumstances.
Say something about control variable
Any variable that’s held constant in a research study.
Kept constant for the reason that it should not influence in any way the result.
The act, process, or technique of selecting a suitable respondents of the research study.
Research Sampling
Selection of group where data collection for research will happen.
Research Sampling
A large collection of individuals or objects that is the main focus of a scientific query.
Population
It is for the benefit of the ________ that researches are done.
population
A _____ isa smaller set of data that a researcher chooses or selects from a larger population using a pre-selected technique.
Sample
A —– refers toa smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.
Sample
A —– refers toa smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.
Sample
process of studying the population by gathering information and analyzing that data. It is the basis of the data where the sample space is enormous.
sampling technique
Types of Sampling Technique
Probability and Non-Probability Sampling Technique
Under Non-Probability Sampling
Judgement Sampling
Convenience Sampling
Availability Sampling
Snowball Sampling
