About This Chapter
Principles & Procedures in Scientific Research - Chapter Summary
Consisting of animated educational videos, this chapter outlines various definitions, techniques and research methods that are used in experimental design and scientific research. While watching the online videos, you can learn about the functions of confounding and extraneous variables, explore scientific theories and laws, and get an understanding of scientific notation. This chapter might assist you with understanding hypotheses, scientific sampling techniques, and the following:
- Explaining the characteristics of the scientific theory
- Describing the steps and terms of the scientific method
- Discovering what happens during a scientific experiment
- Learning about the designing of scientific experiments
- Outlining different kinds of research methods and research variables
- Understanding the differences between inductive and deductive reasoning
- Defining scientific notation and descriptive statistics
- Evaluating the validity of sources
All of the instructor-led video lessons in this chapter aim to increase your knowledge of principles and procedures in scientific research. Click on the timeline feature to discover the main topics of the videos. The Dashboard area includes information on additional courses, and it contains an ask-a-question feature. You'll also be able to make use of the worksheets and text transcripts, some of which include bold terms that you can explore further. The self-assessment quizzes and the practice chapter examination will measure your comprehension.
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. What Are Descriptive Statistics? - Definition and Uses
This lesson is a simple walk-through of the common types of descriptive statistics and why they are important for understanding psychological research. You will likely be familiar with many of them but some you may not be.
13. Assessing the Reliability and Validity of Sources
In the business world, any research material must have support that can provide validity and reliability. The support must be credible and have documentation to show that it is well-researched, professional, peer-reviewed and recent.
