What is an example of reliability?
The term reliability in psychological research refers to the consistency of a research study or measuring test. For example, if a person weighs themselves during the course of a day they would expect to see a similar reading. Scales which measured weight differently each time would be of little use.

In an operational definition, a behavior is explicitly or clearly defined such that it is measurable, can be identified by two or more observers, and can be identified across time and in different settings or contexts. How do you define behavior? A problem or target behavior is the behavior the teacher wants to change.
What is an operational definition of learning?
An operational definition offered in this paper posits learning as a multi-dimensional and multi-phase phenomenon occurring when individuals attempt to solve what they view as a problem. The definition is illustrated by analysis of change occurring in three thinking-aloud interviews with one middle-school teacher.
What are the three types of reliability?
Reliability refers to the consistency of a measure. Psychologists consider three types of consistency: over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater reliability).
How do you define operational terms?
Operational definition of terms refers to a detailed explanation of the technical terms and measurements used during data collection. This is done to standardize the data. Data that is not defined runs the risk of being inconsistent and might not give the same results when the study is replicated.
What are reliability estimates?
Estimation. The goal of estimating reliability is to determine how much of the variability in test scores is due to errors in measurement and how much is due to variability in true scores.
What is an operational definition Six Sigma?
Six Sigma practitioners know that operational definitions are definitions to do business with. An operational definition can be defined as a clear and understandable description of what is to be observed and measured, such that different people collecting, using and interpreting data will do so consistently.
What does reliability mean in sociology?
In the context of research, the reliability of a method refers to the extent to which, were the same study to be repeated, it would produce the same results. For this to be the case, samples need to be representative, questions or processes need to be uniform and data would generally need to be quantitative.

|Type of reliability||Measures the consistency of…|
|Test-retest||The same test over time.|
|Interrater||The same test conducted by different people.|
|Parallel forms||Different versions of a test which are designed to be equivalent.|
|Internal consistency||The individual items of a test.|
What is an operational definition used for?
An operational definition allows the researchers to describe in a specific way what they mean when they use a certain term. Generally, operational definitions are concrete and measurable. Defining variables in this way allows other people to see if the research has validity.
What is an operational definition of intelligence?
Intelligence (in all cultures) is the ability to learn from experience, solve problems, and use our knowledge to adapt to new situations. This tends to be “school smarts” and it tends to be culture-specific. This is the operational definition.
