18 Lessons in Chapter 2: Glencoe Understanding Psychology Chapter 2: Psychological Research
What Is the Scientific Method in Psychology? - Definition, Characteristics & Steps

1. What Is the Scientific Method in Psychology? - Definition, Characteristics & Steps

How might someone apply the scientific method to psychological research? We will review the steps of the scientific method and how they applied to one of the most famous psychological studies ever conducted.

Formulating the Research Hypothesis and Null Hypothesis

2. 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.

Types of Research Designs in Psychology

3. Types of Research Designs in Psychology

What are the three main research designs, and what are their advantages and disadvantages? In this lesson, you'll explore the different goals behind descriptive, correlational and experimental research designs.

Using Archival Research & Secondary Records to Collect Social Research Data

4. Using Archival Research & Secondary Records to Collect Social Research Data

This lesson explores the idea of what happens when researchers already have information and data that they can study. You'll get the chance to look at descriptions of archival and meta-analysis research.

What Is Survey Research? - Definition, Methods & Types

5. What Is Survey Research? - Definition, Methods & Types

This lesson explores the ways a researcher may employ the types of surveys used in research. We will also go over the strengths and weaknesses of each type of survey.

Case Study Design: Definition, Advantages & Disadvantages

6. Case Study Design: Definition, Advantages & Disadvantages

Often, research involves looking at large numbers of people. But sometimes, researchers want to look at just a few people in-depth. In this lesson, we'll examine case studies and their strengths and limitations.

Correlational Research: Definition, Purpose & Examples

7. Correlational Research: Definition, Purpose & Examples

This lesson explores, with the help of two examples, the basic idea of what a correlation is, the general purpose of using correlational research, and how a researcher might use it in a study.

Non-Experimental and Experimental Research: Differences, Advantages & Disadvantages

8. Non-Experimental and Experimental Research: Differences, Advantages & Disadvantages

How is a non-experimental design scientific? We will look at what it means to use experimental and non-experimental designs in the course of psychological research. We will also look at some classic examples of different types of research.

What is a Control Group? - Definition and Use in Research

9. What is a Control Group? - Definition and Use in Research

In research, many times a condition is compared to a group that doesn't receive treatment. In this lesson, we'll look at what a control group is and why it is important.

Research Variables: Dependent, Independent, Control, Extraneous & Moderator

10. 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?

Random Assignment in Research: Definition and Importance

11. Random Assignment in Research: Definition and Importance

In order to get the most accurate results, researchers must choose and assign their subjects in a random manner. In this lesson, we'll look at random assignment, random selection, and why they are important.

Requirements of External Validity: Internal Validity & Replication

12. Requirements of External Validity: Internal Validity & Replication

In order to generalize results from studies to the real world, there are a couple of things that are required. In this lesson, we look at the requirements for external validity: replication and internal validity.

Statistical Significance: Definition, Levels & Critical Regions

13. Statistical Significance: Definition, Levels & Critical Regions

This lesson explores the basic principle of statistical significance and why it is important to understand when performing nearly any statistical test.

Ethical Research: Maintaining Privacy, Anonymity & Confidentiality

14. Ethical Research: Maintaining Privacy, Anonymity & Confidentiality

When performing research, there are certain expectations that a researcher must follow to protect their subjects. We will explore a few of the different ways that a subject's responses are kept from being used against them.

What Is Informed Consent in Research? - Definition & Purpose

15. What Is Informed Consent in Research? - Definition & Purpose

After you have figured out what you are going to research and have approval to do it, you need informed consent from the participants in your experiment. What is informed consent, and how is it different than regular consent?

Reliability and Validity

16. Reliability and Validity

How do validity and reliability contribute to study design in psychology? In this lesson, you'll look at how experiments can fail reliability and validity requirements to get an idea of the challenges behind conducting significant psychological research.

What is Internal Validity in Research? - Definition & Examples

17. What is Internal Validity in Research? - Definition & Examples

The purpose of most research is to show that one variable causes changes in another variable. But, what happens when other variables come into play? In this lesson, we'll explore the definition, importance and threats to internal validity.

Unconditioned Stimulus: Examples & Definition

18. Unconditioned Stimulus: Examples & Definition

An unconditioned stimulus produces an automatic, natural reaction. Read on to find out more about unconditioned stimuli and classical conditioning. Then, test your knowledge with a quiz.
