Kinds of Quantitative research

1. Quantitative Research Kinds of Quantitative Research

2. Learning Competency: Describes characteristics, strengths, weaknesses, and kinds of quantitative research. (CS_RS12-Ia-c-1)

3. Specific Objectives: 1. Identify the different kinds of quantitative research. 2. Decide on suitable kinds of quantitative research in various fields of interest.

4. This kind of research allows the researcher to either describe a situation or phenomenon or the relationship between two or more variables without any interference from the proponent.

5. Descriptive Research Correlational Research Ex post facto

6. Descriptive Research Correlational Research Ex post facto

7. Descriptive Research It deals with describing the nature, characteristics and components of the population or a phenomenon. This is used to describe a particular phenomenon by observing it as it occurs in nature.

8. Descriptive Research There is no experimental manipulation, and the researcher does not start with a hypothesis. The goal of descriptive research is only to describe the person or object of the study.

9. Descriptive Research Example: the determination of the different kinds of physical activities and how often high school students do it during the quarantine period Determination of number of hours senior high school students spend in surfing the internet

10. Descriptive Research There are three ways a researcher cam go about doing a descriptive research project and they are: Observational – defined as a method of viewing and recording the participants Case study – defined as an in-depth study of an individual or group of individuals Survey – defined as a brief interview or discussion with an individual about a specific topic.

11. Descriptive Research Correlational Research Ex post facto It is primarily concerned with an orderly or systematic investigation of the nature of relationships, or associations between and among variables without necessarily investigating into casual reasons underlying them. Furthermore, it is also concerned with, the extent of relationships that exists between or among the variables.

12. 2. Correlational Research Examples: if Performance in Mathematics can be used to predict performance then, the higher the Mathematics grade, the higher most likely be the score in Practical Research 2. Determination if the following factors are related to each other: sex and mathematical ability, age and leadership style, and occupation and life span.

13. Descriptive Research Correlational Research Ex post facto It is used to investigate a possible relationship between previous events and present conditions. The term “Ex post facto” which means after the fact, looks at the possible causes of an already occurring phenomenon. Just like the first two, there is no experimental manipulation in this design.

14. 3. Ex post facto Examples: “How does the parent’s academic achievement affect the children obesity?”

15. 1. Quasi-Experimental Research 2. True Experimental Research

16. 1. Quasi-Experimental Research This is used to establish the cause-and-effect relationship of variables. Although it resembles the experimental design, the quasi-experimental has lesser validity due to the absence of random selection and assignment of subjects. Here, the independent variable is identified but not manipulated. 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): 2. True Experimental Research

17. 1. Quasi-Experimental Research Example: the effects of unemployment on attitude towards following safety protocol in ECQ declared areas.

18. Quasi-Experimental Research This is used to establish the cause-and-effect relationship of two or more variables. This design provides a more conclusive result because it uses random assignment of subjects and experimental manipulations. This kind of research can be identified by three characteristics: randomly formed groups, manipulation of the treatment (the IV), and comparisons among groups. 2. True Experimental Research

19. 2. True Experimental Research Example: a comparison of the effects of various blended learning to the reading comprehension of elementary pupils.
