4. Experimental Research Experimental research is a quantitative research that manipulates some level of independent variable and then measures the outcome through the dependent variable . It determines cause and effect relationship.

5. Experimental Research The quantitative research treats or deals with the object or subject of the research in a definite or exact manner and determines the extent of the effects or influence of the treatment on the object, then discovers the causes of such effect.

6. 2 Groups in Experimental Research The experimental group , the one on which the treatment or influence is applied. The control group , which does not receive any treatment.

7. Two Categories of Experimental Research True experimental Quasi-experimental

8. True Experimental R esearch Done in a laboratory or in the field Uses random selection of participants Measures the effect of independent variable (cause) to the dependent variable (effect). The researcher can control the independent variable

9. Quasi-Experimental Research Alternative to determine cause and effect between two variables but cannot be subjected to experimental control. Most of the time, this design is used on a naturally given phenomena (something that cannot be controlled) and its effect to people. No random assignment of participants.

10. Non-Experimental Research Non-Experimental research is a way of finding truths about a subject by describing the collected data about such subject and determining their relationships or connections with one another. Any treatment or conditions is not involved in this type of research. But there is a measuring variable here; once you do a non-experimental research, you deal both with qualitative and quantitative.

11. Non-Experimental Research Is a research that lacks the manipulation of an independent variable and random assignments of participants to conditions. It determines correlation, interaction, connection or relationship of variables.

12. The desire to discover people’s thoughts, views, feelings and attitudes about a certain societal issue, object, place or event causes you to use non-experimental research. The variables should be measurable, meaning they can be counted or subjected to scale .

13. It can be a causal relationship, but the independent variable cannot be manipulated, or participants cannot be randomly assigned to conditions. It collects data through survey, observation, historical studies, case studies, documentary analysis, etc .

14. Characteristics of Non-Experimental Research 1. It is incapable of establishing cause-effect relationships; by itself, it is able, if it takes place in conjunction with other experimental and quasi-experimental research methods. Example: It has been noted that when ice cream sales are higher, so is the murder rate. But that doesn't mean that ice cream causes people to kill. Ice cream sales go up in the summer and criminals are more active at that time of year too, but the one doesn't have anything to do with the other. This is an example of a correlation. but not a causation.

15. Characteristics of Non-Experimental Research 2. It involves ways of data analysis: Primary — analysis of data collected by the researcher himself Secondary — examination of data collected by other people Meta-analysis — analysis of data expressed numerically

16. 3. It uses research method that is applicable to both quantitative and qualitative data. 4. It collects data through survey, observation, historical studies, case studies, documentary analysis, etc.

17. Survey research is a method of research that aims at knowing what a big number of people think about some sociological issues. The data it collects from these people serving as the “ representatives or informants ” explain or describe the society’s thoughts, attitudes and feelings towards these issues.

18. Strengths of Survey Research 1. It is versatile . It can tackle any issue. 2. It is efficient. It is not costly in terms of money and time. 3. Generality. It can get a good sample. 4. It can provide confidentiality, safeguarding the privacy and anonymity of the respondents.

19. Types of Non-Experimental Research : 1. Descriptive — aims to accurately and systematically describe a population, situation or phenomenon. It answers the questions what, when, where and how. Identifies characteristics, frequencies, trends, correlations and categories.

20. Types of Non-Experimental Research : 2. Correlational Research - attempts to determine the level or strength of two or more quantifiable variables does not mean that one variable causes the other.

21. Types of Non-Experimental Research: 3. Causal Comparative — Causal comparative research attempts to determine relationship between independent variable and dependent variable after an action or event has already occurred.

22. Reminders: Make a Research Group consisting of 6 to 7 persons. Choose 1 Research Representative. Think a good quantitative research title (quasi-experimental / correlational as much as possible). 25 items Quiz during your asynchronous schedule. Multiple choice. Coverage from week 1 to 3.
