CARA MENENTUKAN JENIS PENELITIAN KUANTITATIF

Summary

The video explains how to determine the type and methodology of quantitative research, focusing on distinguishing between experimental and non-experimental designs. It offers guidance on identifying whether research involves controlled variables, such as in true experiments or quasi-experiments, or if it follows non-experimental methods like surveys, ex post facto studies, or correlational studies. The video provides a step-by-step approach to help researchers decide based on their data type—whether it’s qualitative or quantitative—and how variables interact within their study.

Takeaways

• 🔍 To determine the type of research, identify whether it's experimental or non-experimental.
• 📊 Quantitative research involves numerical data, while qualitative research involves non-numerical data.
• 🧪 If the researcher controls all independent variables, the research is experimental.
• 🔄 Experimental research can be true-experiment or quasi-experiment, depending on sample selection.
• 🎯 True-experiment involves random sampling and control over variables, while quasi-experiment does not.
• 📝 If the researcher does not control the independent variables, the research is non-experimental.
• 📈 Non-experimental research types include survey, ex-post facto, and correlational studies.
• 🔗 Correlational research examines the relationship between two or more variables.
• 🧮 Ex-post facto research studies events or phenomena without manipulating variables.
• 📊 Survey research collects data by observing existing facts without altering variables.

Q & A

What is the first step in determining the type of research?

The first step is to determine whether the data is in the form of numbers (quantitative) or words (qualitative).

What type of research is conducted if the data is numerical?

If the data is numerical, the research is quantitative.

How can you distinguish between experimental and non-experimental research in quantitative studies?

You can distinguish between experimental and non-experimental research by determining whether the researcher controls all independent variables. If they do, it is experimental; if not, it is non-experimental.

What defines true experimental research?

True experimental research is defined by the random selection of samples and the researcher having full control over the independent variables.

What is the main characteristic of quasi-experimental research?

Quasi-experimental research involves the researcher not fully controlling the sample selection or using non-random methods.

When is a study categorized as non-experimental?

A study is categorized as non-experimental if the researcher does not control the independent variables.

What types of studies fall under non-experimental research?

Non-experimental research can include survey, ex post facto, and correlational studies.

What is the defining feature of a survey study?

A survey study examines facts or situations as they are without looking for variable changes.

What does a correlational study focus on?

A correlational study focuses on the relationship and strength between two or more variables.

What is ex post facto research?

Ex post facto research examines cause-and-effect relationships after an event has already occurred, without manipulating variables.
