**[OBJECTIVES]** a\. Differentiate Experimental from Non-Experimental Research b\. Identify and describe types of Experimental Research. c\. Identify and describe types of Non-Experimental Research **Types of Quantitative Research** **[RESEARCH DESIGN]** Research Design is important in identifying the approach to be used in solving a particular problem. Research design is an overall strategy to follow in a logical way to ensure that the research problem is addressed correctly. Research design includes the description of the selection, measurement, and analysis of the data. **[EXPERIMENTAL RESEARCH]** It is used to identify "cause and effect relationships between variables." It is composed of the [**control group**,] the samples [not exposed to experimental treatment], and the [**experimental group** exposed to the treatment]. It uses one or more dependent and independent variables being tested to determine the effect on each other. The researcher is allowed to do manipulation of the controlled variables. The subjects or participants in the study are randomly or non-randomly selected. 01 **Kinds Of Experimental Research** **[A. PRE-EXPERIMENTAL RESEARCH DESIGN]** It is considered the simplest experimental design. In using this design, the researcher studies a single group and does not make any comparisons between this group and an equivalent treatment group. The single group, pre-test-post-test design is one example of a pre-experimental research design wherein the group is measured two times before and after the intervention. The Pre-Test and Post-Test of the group are not being compared; instead, the Post-Test of the treated group is compared to the Post-Test of the untreated group. **[B. TRUE-EXPERIMENTAL RESEARCH DESIGN]** A true-experimental design should have the following criteria: (a) An experimental variable is manipulated by the researcher,(b)the researcher has control over the independent variables as well as the treatment of the subjects,(c) one experimental and one control group should be present, and; (d)the subjects or participants are randomly assigned either to the control or experimental group. **Types of True-Experimental Research** **1. Pre-Test-Post-Test Design** Experimental and Controlled groups are formed. The pre-test is given on both groups for the independent variable. Only the experimental group will be assigned the treatment. Both groups will be given the Post-Test to measure the effect of the independent variable on the dependent variable. **2. Post-Test Only Design** Experimental and Controlled groups are formed. Only the experimental group will be given the treatment. Both groups will be given the Post-Test to measure the effect of the treatment. This type of experimental research is done if it is impossible to provide a Pre-Test on the subjects or participants. **3. Solomon Four Group Design** It is considered the most reliable experimental design since four groups are randomly formed: two experimental groups and two control groups. This method combines the first two methods wherein only two groups will be pre-tested(one experimental and one controlled group), then one pre-tested group and one un-pretested group get the treatment. All four groups receive the Post-Test. The Post-Test result will show the effects of the dependent variable compared to the independent variable\'s effects on the dependent variable. **[C. QUASI-EXPERIMENTAL RESEARCH]** The criterion of quasi-experimental research is identical to true experimental research. The only difference is that subjects are not randomly selected. **Types of Quasi-Experimental Design** **1. Non-Equivalent Control Group Design** Similar to Pre-Test-Post-Test design under True Experimental Research, only that, the subjects are not randomly selected. **2. Time Series Design** Multiple measures are done before and after the experimental intervention. The researcher observes or measures the subject periodically. Not only one Pre-test or Post-test is given to the subjects. The researcher believes that time threats affect the intervention it measures. Thus it should be done in a time series. **[NON-EXPERIMENTAL RESEARCH]** In a Non-Experimental Research Design, [**the researcher does not manipulate nor control**] the setting or environment of the research. It is the type of research that does not involve the manipulation of control or independent variable. The researcher observes and collects data as the phenomena occur naturally. This kind of research is usually used if the research pertains to a [**non-causal relationship**] between variables. 02 **Kinds Of Non-Experimental Research** **[DESCRIPTIVE RESEARCH DESIGN]** is an example of Non-Experimental Research, which aims to observe and describe a certain situation or phenomena as it occurs naturally. **Types of Descriptive Research Design** **1. Survey Research** It is used when the researcher needs to provide a quantitative description of a population\'s trends, attitudes, behavior, or opinions. **2. Correlational Research** It is used to determine the magnitude and direction of relationships among variables in a population. **3. Comparative Research** It is used to compare and contrast representative samples from two or more groups of subjects in relation **Directions: Write E if the statement describes Experimental Research or N if Non-Experimental Research.** 1\. It is used for research that describes the non-causal relationship among variables. 2\. The researcher does not control the research setting. 3\. The researcher manipulates one or two variables in the research. 4\. It is commonly called scientific research. 5\. Descriptive research design is used in this type of research method **Directions: Write E if the statement describes Experimental Research or N if Non-Experimental Research.** 6\. It has a controlled and uncontrolled group. 7\. Participants of the study are may be selected randomly or non-random. 8\. It is used to identify cause and effect relationships among variables. 9\. It does not involve the manipulation of variables. 10\. It is used to observe and describe phenomena as it occurs naturally. **Complete the following paragraph with the concepts learned\ in this module.** **Complete the following paragraph with the concepts learned\ in this module.** **Complete the following paragraph with the concepts learned\ in this module.** SCHOOL HANDMADE ICONS SCHOOL HANDMADE ICONS II Business Icons Teamwork Icons Help & Support Icons Avatar Icons Creative Process Icons Performing Arts Icons Nature Icons
