2. HELLO! Joven P. De Asis 2

3. 4 At the end of the lesson the students should be able to: define quantitative research; describe the characteristics of quantitative research; identify the strengths and weaknesses of quantitative research; and explain the kinds of quantitative research.

4. 5 Quantitative research Quantitative research is the process of collecting and analyzing numerical data. It is an objective, systematic empirical investigation of observable phenomena through the use of computational techniques.

5. 6 The word research was coined from the French word " cerhier " which means seek . The prefix "re" means to repeat . Literally, research is to repeat looking for something.

6. 7   1. Objective. Quantitative research seeks accurate measurement and analysis of target concepts. It is not based on mere intuitions and guesses. 2. Clearly Defined Research Questions. In quantitative research, the researchers know in advance what they are looking for. The research questions are well-defined for which objective answers are sought. Characteristics of Quantitative Research

7. 8 3. Structured Research Instruments. Data are normally gathered using structured research tools such as questionnaires to characteristics to collect measurable characteristics of the population like age, socio-economic status, number of children, among others. 4. Numerical Data. Data are in the form of numbers and statistics, often organized and presented using tables, charts, graphs and figures that consolidate large numbers of data to show trends, relationships, or differences among variables.

8. 9 6. Replication. Reliable quantitative studies can be repeated to verify or confirm the correctness of the results in another setting. This strengthens the validity of the findings thus eliminating the possibility of spurious conclusions. 5. Large Sample Sizes. To arrive at a more reliable data analysis, a normal population distribution curve is preferred. This requires a large sample size, depending on how the characteristics of the population vary.

9. 10 7. Future Outcomes. By using complex mathematical calculations and with the aid of computers, if-then scenarios may be formulated thus predicting future results.

10. 11 Strengths of Quantitative Research The advantages of quantitative research include: 1. It is objective. Since it provides numerical data, it can't be easily misinterpreted. 2. The use of statistical techniques facilitates sophisticated analyses and allows you to comprehend a huge amount of vital characteristics of data. 3. The numerical data can be analyzed in a quick and easy way. By employing statistically valid random models, findings can be generalized to the about which information is necessary. 4 Quantitative studies are replicable. Standardized approaches allow the study to be replicated in different areas or over time with the formulation of comparable findings

11. 12  Weaknesses of Quantitative Research   The disadvantages of quantitative research are as follows: 1 Quantitative research requires a large number of respondents . It is assumed that the larger the sample is, the more statistically accurate the findings are. 2. It is costly. Since, there are more respondents compared to qualitative research, the expenses will be greater in reaching out to these people and in reproducing the questionnaires. 3. The information on contextual factors to help interpret the results or to explain variations are usually ignored . It does not consider the distinct capacity of the respondents to share and elaborate further information unlike the qualitative research

12. 13 4. Many information are difficult to gather using structured research instruments, specifically on sensitive issues like pre-marital sex, domestic violence, among others. 5. If not done seriously and correctly, data from questionnaires may be incomplete and inaccurate . Researchers must be on the look-out on respondents who are just guessing in answering the instrument.

13. 14 Kinds of Quantitative Research   Descriptive Research. This design is concerned with describing the nature, characteristics and components of the population or a phenomenon. Descriptive research is used if, for example, you want to know how many hours senior high school students spend in social media, the number of malnourished students who failed in the achievement test, and how healthy is the food served during recess in the public schools.      

14. 15 Correlational Research It is the systematic investigation of the nature of relationships, or associations between and among variables without necessarily investigating into causal reasons underlying them. It is also concerned with the extent of relationships that exists between or among the variables. For example, if pre-board examination results can be used to predict performance in the Licensure Examination for Teachers (LET), then the higher the pre-board grade, the higher most likely be the score in the LET.

15. 16 Evaluation Research This kind of research aims to assess the effect, impacts or outcomes of practices, policies or programs . Assessing the implementation nursing care in a hospital and determining the impact of a new treatment procedure for patients are examples of evaluation research.      

16. 17 Survey Research A survey research is used to gather information from a group of people by selecting and studying samples chosen from a population. It may done in various ways like face-to-face, phone, mail, and online.   C ross-sectional research Information is collected from a sample in just single point in time just like the child-rearing practices of single parents, and population control practices of unmarried couples. L ongitudinal Research T he researcher collects information on the same subjects over a period of time sometimes lasting many years in order to study the changes through the years Longitudinal survey is utilized, for example, to determine the growth of rice yield in the country and the rate of promotion of doctorate degree holders five years after earning the degree.

17. 18 Causal-Comparative Research It is also known as ex post facto (after the fact) research. This kind of research derives conclusion from observations and manifestations that already occurred in the past and now compared to some dependent variables. It discusses why and how a phenomenon occurs. For example, a researcher is interested in how weight influences stress-coping level of adults.   Experimental Research This research utilizes scientific method to test cause and-effect relationships under conditions controlled by the researcher. For example, teaching strategies.

18. 19 A quasi-experimental design The researcher does not modify pre-existing groups of subjects. The group exposed to treatment (experimental) is compared to the group unexposed to treatment (control.
