Ch 4: Sampling and Measurement: Homeschool Curriculum

About This Chapter

The Sampling and Measurement unit of this High School Psychology Homeschool course is designed to help homeschooled students learn about the importance of sampling and measurement in psychological research. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our High School Psychology Homeschool course will benefit any student who is trying to learn about the types and reliability of measurements. There is no faster or easier way to learn about psychology. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn to make the distinction between qualitative and quantitative measurements.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a psychology curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a Sampling and Measurement unit exam confirm understanding or identify any topics that require review.

Sampling and Measurement Unit Objectives:

  • Define the reliability of measurement.
  • Explain interrater and interitem.
  • Learn the importance of test-retest reliability.
  • Learn about validity and reliability.
  • Explain the various types of validity.
  • Discuss constructs as well as direct and indirect measurements.
  • Explore random assignment in research.

What is Sampling in Research? - Definition, Methods & Importance

1. What is Sampling in Research? - Definition, Methods & Importance

The sample of a study can have a profound impact on the outcome of a study. In this lesson, we'll look at the procedure for drawing a sample and why it is so important to draw a sample that represents the population.

The Relationship Between Population, Sample & Generalizability

2. The Relationship Between Population, Sample & Generalizability

Researchers try their best to gather a sample that represents their population. But why is this important? In this lesson, we'll look at the relationship between population, sample, and generalizability in research.

Random Assignment in Research: Definition and Importance

3. 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.

The Importance of Measurement in the Research Process

4. The Importance of Measurement in the Research Process

Why is it important to measure variables in a study? And, how do you go about doing it? In this lesson, we'll examine the importance of measurement, along with some common types of psychological measurement.

Types of Measurement: Direct, Indirect & Constructs

5. Types of Measurement: Direct, Indirect & Constructs

How do you measure psychological traits? In this lesson, we'll look at how psychologists measure traits, including direct and indirect observation. We will also explore why psychological traits are so difficult to measure.

The Difference Between Qualitative & Quantitative Measurement

6. The Difference Between Qualitative & Quantitative Measurement

In research, there are generally two types of data. In this lesson, we'll look at quantitative and qualitative measurement, when each are used, and how researchers can sometimes use both.

The Reliability of Measurement: Definition, Importance & Types

7. The Reliability of Measurement: Definition, Importance & Types

Psychologists use tools like surveys and tests to measure psychological traits. But, what happens when a measurement tool is not consistent? In this lesson, we'll examine what reliability is, why it is important, and some major types.

Methods for Improving Measurement Reliability

8. Methods for Improving Measurement Reliability

Reliability is the consistency of the results of a measurement tool. But, what causes a tool to have low reliability? And, what can be done to improve reliability? In this lesson, we'll answer both of those questions.

The Validity of Measurement: Definition, Importance & Types

9. The Validity of Measurement: Definition, Importance & Types

How do you know if you are measuring what you actually want to measure? In this lesson, we'll look at what validity is, why it is important, and four major types of validity: face, construct, content, and predictive validity.

The Relationship Between Reliability & Validity

10. The Relationship Between Reliability & Validity

Though reliability and validity are different from each other, they are still related. In this lesson, we'll look at the differences of and relationship between reliability and validity.

What is Internal Validity in Research? - Definition & Examples

11. 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.
