10. Standard Deviation in Psychology: Formula & Definition
Standard deviations are scores around the mean of a distribution. It measures how much a set of scores is dispersed around an average measure of variability. Deviations around the mean can be calculated to express it as a variance or a standard deviation.
11. Statistical Significance: Definition & Levels
In this lesson you will learn to define statistical significance as well as learn how it is determined. Following this lesson you will have the opportunity to test your knowledge with a short quiz.
12. Validity in Psychology: Types & Definition
Validity refers to a test's ability to measure what it is supposed to measure. Learn more about the different types of validity and why they are important, and test your knowledge with a quiz.
13. Variable Interval and the Schedule of Reinforcement: Examples & Overview
In this lesson, you will learn what variable-interval schedules of reinforcement are and how they are utilized in everyday life. Following completion of this lesson, you will have the opportunity to test your knowledge with a short quiz.
