About This Chapter
Principles and Procedures of Scientific Inquiry - Chapter Summary
Across the many fields of science, there are certain principles scientists follow when conducting research. If you need to review scientific research procedures, the video and text lessons in this chapter cover relevant concepts and key terms. You'll examine exactly what scientific research entails and take a look at different types of experiments. Our professional instructors also go over the scientific method and types of reasoning. You will have the chance to interpret scientific data presented in visual form. After completing the chapter, you should be able to:
- List characteristics of scientific theories
- Identify steps of the scientific method
- Describe experimental design in science
- Understand research methods and variables
- Develop research and null hypotheses
- Explain scientific sampling techniques
- Distinguish between inductive and deductive reasoning
- Correctly use scientific notation
- Interpret data from tables, graphs and charts
To help you review scientific research methods, we offer fun video and text lessons that typically take less than 10 minutes of your time. Each video includes tags so that you can look back at key points without having to re-watch entire lessons. Videos are coupled with transcripts often containing useful links to other text lessons, highlighted key terms and self-assessment quizzes. The multiple-choice quizzes are brief and enable you to gauge your understanding of the material presented.
1. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
2. What is the Scientific Theory? - Definition, Characteristics & Example
In this lesson, you'll learn the definition and characteristics of a scientific theory and understand how theories are formulated. You'll see examples of scientific theories, and after the lesson you can test your knowledge with a brief quiz.
3. 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.
4. Scientific Experiment: Definition & Examples
In this lesson, you will learn about the process of a scientific experiment. First, the lesson will outline the definition and give a short history of scientific experimentation. Then the types will be described and, finally, an example of a scientific experiment will be provided.
5. 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.
6. 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.
7. Research Variables: Dependent, Independent, Control, Extraneous & Moderator
This lesson explores the terminology of experimental design. What are variables? How do they influence each other? Is it possible that you are seeing connections that don't actually exist?
8. Formulating the Research Hypothesis and Null Hypothesis
After figuring out what you want to study, what is the next step in designing a research experiment? You, the researcher, write a hypothesis and null hypothesis. This lesson explores the process and terminology used in writing a hypothesis and null hypothesis.
9. Sampling Techniques In Scientific Investigations
We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.
10. Inductive vs. Deductive Reasoning: Differences & Examples
This lesson explores the difference between inductive and deductive reasoning in the form of psychological experiments. In addition to defining these terms, the lesson gives examples to explain how this reasoning is applied.
11. Scientific Notation: Definition and Examples
Scientific notation is a special way of writing numbers so they are easier to work with. This lesson will define scientific notations and show some examples of how to convert numbers from standard notation to scientific notation and back.
12. Interpreting Tables of Scientific Data: Practice Problems
Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
13. Interpreting Graphs and Charts of Scientific Data: Practice Problems
Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.
