About This Chapter
Scientific Research & Experiments - Chapter Summary
If you're having trouble remembering the difference between qualitative and quantitative data, check out this chapter. The video lessons cover not only types of data but also types of research methods, including observation and experimentation. In addition, you'll review the components of strong hypotheses and studies. After studying our short video lessons, you'll be able to tackle the following:
- Identify the types of research methods
- List the steps of the scientific method
- Explain how to formulate a scientific hypothesis
- Recognize the components of experimental design
- Distinguish between quantitative and qualitative data
- Discuss the importance of reliability and validity in research studies
With our videos lasting a few minutes, you can easily and quickly fit study sessions into your hectic schedule. The video lessons contain many images, diagrams and animations to enforce the instructors' explanations of science concepts. You also have access to lesson transcripts and self-assessment quizzes in a multiple-choice format.
1. What Are The Different Kinds of Research Methods?
This lesson will go over some important research methods, including observation, correlation, and experimentation, as well as examples of each type of methodology.
2. The Scientific Method: Steps, Terms & Examples
The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.
3. Developing a Scientific Hypothesis
This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.
4. Experimental Design in Science: Definition & Method
What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.
5. Validity and Reliability: How to Assess the Quality of a Research Study
Many psychologists and teachers complete research studies. How can you tell if a study was done well? This lesson will cover many criteria for a good quality study, including types of reliability and validity.
6. Qualitative vs. Quantitative Data in Various Research Methods
Qualitative data and quantitative data are both useful in research, but it is important to understand the differences between the two. Learn how to differentiate the two types of data in this lesson.
