Lesson 1 - Quantitative and Qualitative Characteristics of Research Flashcards
(29 cards)
anything that can be counted or measured; numerical data commonly expressed in graphs and numbers
Quantitative data
descriptive, referring to things that can be observed but not measured
Qualitative data
experiments, observations recorded as numbers, and surveys with closed-ended questions.
quantitative methods
interviews with open-ended questions, observations described in words, and literature reviews that explore concepts and theories.
qualitative methods
Kind of research that is subjective, no close-ended questions, and does not have clearly structured instruments.
Qualitative Research
Presents textural data and does not require a large sample size
Qualitative Research
this research cannot be replicated; explains the past and present outcomes
Qualitative Research
the process of looking for information once again
Research
‘re’ - again
‘search’ - to look for
research’s main objective
answer questions and acquire new information
research done scientifically is more accurate, reliable, and valid
tama tama
kind of research that is objective and requires a large sample size, can be replicated, and predicts future outcomes.
Quantitative Research
does not verify existing facts but develops a new concept
Qualitative Research
verifies existing facts and develops new concepts
Quantitative Research
Importance of quantitative research in Education
students develop critical thinking, effective, analytical, research and communication skills
Importance of quantitative research in Business
products innovates and service improves
Importance of quantitative research in Science
discovers prevention and cure to diseases, means of people’s safety and health
7 characteristics of Quantitative Research
Numerical in nature
objective, accurate, valid, and predictive
bigger sample size
use of well-structured research instruments
use of tables, charts, and graphs
use of statistical treatment
replicable
[+] use of close-ended questions
studies under quantitative research requires measurable information (ex. age, weight, temperature, etc.)
Numerical in Nature
focused on testing specific hypothesis and observes behaviors under controlled setting; findings aim to form generalizations of predictions applicable to bigger populations
objective, accurate, valid, and predictive
usually applied in determining the number of respondents; the greater the participants, the more reliable the data is (lesser biases)
bigger sample size
-random sampling techniques
survey questionnaires validated by experts; designed to gather specific information for respondents (usually multiple choice questions)
use of well-structured research instruments
- research instruments
visual representation of the collected data for the summary of findings
use of tables, charts, and graphs
provide distribution of recorded data values in frequencies and percentage
Tables
present a trend or pattern between or among data values
Charts and graphs
