The Importance of Measurement in the Research Process

1. 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.

The Difference Between Qualitative & Quantitative Measurement

2. 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.

Conceptualization & Operationalization in Measurement

3. Conceptualization & Operationalization in Measurement

When designing a study, how do you make sure that everyone knows what you're talking about? How do you measure things that seem difficult to measure? In this lesson, we'll look at two key steps in research: conceptualization and operationalization.

Continuous, Discrete & Categorical Variables: Definition and Examples

4. Continuous, Discrete & Categorical Variables: Definition and Examples

When doing research, variables come in many types. In this lesson, we'll explore the three most common types of variables: continuous, discrete, and categorical.

Scales of Measurement: Nominal, Ordinal, Interval & Ratio

5. Scales of Measurement: Nominal, Ordinal, Interval & Ratio

When doing research, variables are described on four major scales. In this lesson, we'll look at the major scales of measurement, including nominal, ordinal, interval, and ratio scales.

Types of Tests: Norm-Referenced vs. Criterion-Referenced

6. Types of Tests: Norm-Referenced vs. Criterion-Referenced

What's the best way to score tests? In this lesson, we'll look at two major types of tests that are scored differently from each other: norm-referenced and criterion-referenced tests.

Types of Measurement: Direct, Indirect & Constructs

7. 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.

Commonly Used Research Measurement Scales

8. Commonly Used Research Measurement Scales

How do you measure a person's thoughts or feelings when you can't see them? In this lesson, we'll look at common measurement scales that psychologists use when examining thoughts and feelings.

The Reliability of Measurement: Definition, Importance & Types

9. 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

10. 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

11. 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

12. 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.

Causation in Psychology Research: Examples & Definition

13. Causation in Psychology Research: Examples & Definition

Many people get causation and correlation confused, although both terms are used frequently. In this lesson, you will learn the difference between the two and how psychologists go about determining causation.

Convenience Sample: Example & Definition

14. Convenience Sample: Example & Definition

Conducting true experiments is expensive and time-consuming. However, by using a sample of a population that is convenient, the cost and time required to conduct it are greatly reduced. So, why not do that for every experiment?

Predictor Variable: Definition & Example

15. Predictor Variable: Definition & Example

Did you know predictor variables are commonly used in nonexperimental research designs? Learn more about predictor variables from examples, and then test your knowledge with a quiz.
