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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
