Variable-Interval refers to a type of reinforcement schedule in which rewards or consequences are provided after varying amounts of time have passed, based on an unpredictable pattern. In psychology, particularly in behavioural psychology and operant conditioning, this schedule is used to reinforce behaviours intermittently, keeping the subject engaged in the behaviour even though the exact timing of the next reward is unknown.

Variable-Ratio refers to a type of reinforcement schedule in which rewards are given after an unpredictable number of responses. In psychology, particularly in the context of operant conditioning, this reinforcement schedule is used to encourage high and consistent rates of behaviour because the subject never knows exactly when the next reward will occur, but knows that the reward is tied to repeated behaviour.

The variance is the average squared deviation around the mean; the standard deviation squared.
A measure of the dispersion of a frequency distribution in which each score is subtracted from the mean, squared, and summed. The sum is then divided by the number of scores.
In psychology, variance refers to the measure of the spread between numbers in a data set, indicating how much the numbers differ from each other and from the mean. It is a statistical concept used to describe the degree of diversity or variability in variables, such as scores, traits, or behaviors within a group of people.

The term "variation" refers to the natural differences and diversity that exist among individuals in terms of their thoughts, behaviors, emotions, and other psychological attributes. Variation is a fundamental aspect of human nature and is influenced by a combination of genetic, environmental, cultural, and developmental factors. Understanding variation is essential in psychology as it helps researchers and practitioners appreciate the range of human experiences and behaviors.
