differences between quantative and qualitive method

MEMBERS : LAN ANH BÌNH MINH YẾN NHI NGUYỄN HẰNG KIM TÂM BÁCH NHÃ What are the differences between qualitative and quantitative method? What are the major research methods? The differences between qualitative and quantitative methods : Qualitative Methods Quantitative Methods Collecting non-numeric data Collecting numerical data that can be quantified Methods include focus groups, in-depth interviews, and reviews ,content analysis,observation Methods include questionnaire surveys,reviews, content analysis,observation This is an inductive process which is used to formulate theory. This is a deductive process which is used to test pre-specified concepts, constructs, and hypotheses that make up a theory It describes a problem or condition from the point of view of people experiencing it it provides observed effects of a program on a problem or condition ( Qualitative Methods ) ( Quantitative Method ) Text-based Number-based No statistical tests Statistical tests are used for analysis Can be valid and reliable: depends on skill of the researcher Can be valid and reliable: depends on the measurement device or instrument Take less time on the planning end and more time during the analysis process Take more time on the planning end and less time during the analysis process Less generalizable More generalizable Existing information Experimental Research In-depth interview/ Focus groups Participant observation Content analysis observation Questionnaire Surveys • It is a research project by looking at sources like encyclopedias and other reference books, CD-ROMs, community surveys, government reports and Australian Bureau of Statistics (ABS) data. • Tell us what is already known about your research area. • These information you collect will be both qualitative and quantitative. It is used for historical research FOR EXAMPLE: create a new kind of medicine , a new machine for education,agriculture,Industry [...]... observe It is a method that involves colleting data from a large number of people (more than forty),a questionnaire might be worthwhile They are of two types: + Self-completed where we hand out and mail the questionnaire + Researcher –completed where we ask the questions and complete the form ourselves It is used for descriptive ,explanatory ,and evaluative forms of research For example We can hand out a... the method that we participate in what we are researching It is used for descriptive and evaluative research For example Evaluating the food quality of a restaurant,we participate in observing the way the chefs cook For example Evaluating the food quality of a restaurant,we participate in observing the way the chefs cook A research: The differences about lifestyle between peole living in rural areas and. .. about 5 groups of students in different classes who used to learn with his method They are useful for explanatory and evaluate researches It is a method which we use to analyze existing material such as newspapers, historical and other documents, television programs, magazines or books It is used for descriptive , explanatory and evaluative research FOR EXAMPLE If we want to analyze “climate change",... improve listening skill everyday For example We can hand out a list of questions to survey the quality of a product Which age groups are interested in it? Is it good or bad? What are strong and weak points of the product? How many percent of people like and don’t like? It is a method that involves testing a hypothesis It is used for explanatory and evaluative research For example: A hypothesis:watching... analysize a graph which show world population growth or show the number of people who suffer from AIDS in Africa to find out how it changes and what information we can collect It is a method which we look at or observing some form of behaviour It is used for descriptive and evaluative research FOR EXAMPLE Evaluate the quality of A high school By observing students at this high school Do they go to school... University are very deligent” Interview some teachers who taught them and ask if they agree or not Interview some students how many time they spend for studying A focus group is similar to an indepth interview but you gather the information for a small discussion group, usually up to eight people For example: We want to know if the teaching method that teacher A use is effective or not We interview about...It is a method which we carry out interviewing small number of people (ten or less) from whom you need a lot of detailed information, consider using individual in-depth interviewers Typically we would develop a list of open-ended questions and base your interview around these FOR EXAMPLE Hypothesis :students nowadays are lazier .
