PRACTICAL RESEARCH 2 Flashcards
-systematic study about a specific problem
- used to establish facts
Research
- generalize results from a sample to the population
- large number of cases
- based on precise measurements
- statistical relationships
Quantitative
Characteristics of Quantitative
- Objective, unbiased
- Clearly defined questions
- Structured research instruments
- numerical data and statistical treatment
- Replicable
- Future outcomes
Strengths
- Fast speed data collection
- Findings can be generalized
- easy to analyze data
- consistent and reliable data
- can be anonymous
- objective
weaknesses
- requires a large number of respondents
- costly and expensive
- secondary data may be unavailable
- extensive stat analysis
- Very little room for depressing areas and uncertainty
Kinds of Quantitative Research
- Descriptive
- Correlational
- Quasi Experimental
- Experimental
seeks to describe the current status of an identified variable
Descriptive research
determine the extent of the relationship of 2 or more variables using stratified data
- NO INTERVENTION
Correlational Research
attempts to establish cause effect relationships among the variable
Quasi Experimental
__________ is identified but not manipulated by the experimenter
Independent Variable
uses the scientific method to establish cause-effect relationship
Experimental Research
experimental research are _______ assigned
Randomly Assigned
- are measurable characteristics
- can manipulate/control
Variables
Types of Variables
- Categorical
- Quantitative
any variable that is a category or type
Categorical
Types of Categorical
Nominal
Ordinal
Represents categories that cannot be ordered in any way
- eye color, barangay, religion
Nominal
categories that can be ranked or ordered
- income bracket, student classification
Ordinal
variables where the measure has a numerical meaning
- height weight number of students
Quantitative
Types of numerical
Interval
Ratio
No true zero, only uses addition subtraction
Interval
have true zero,
Ratio
Is a compilation, classification and evaluation of what other researchers have written on a particular topic
