- Only about 13,448 ft/4100m of Mauna Loa are above sea level, so it may not seem like a very tall mountain. But, when you start measuring Mauna Loa from its true base on the bottom of the ocean, in the Hawaiian Trough, the total height exceeds that of Everest by over 3/4 of a mile.

- A: When an error, or blunder, as human errors are called in science, strikes an experimental setup, the appropriate response from the experimental team ranges from ignoring it to voiding the results, depending on the blunder's severity.

Psychology as a Science Home › Research Methods › Experimental Method. The prime method of inquiry in science is the experiment. The key features are control over variables, careful measurement, and establishing cause and effect relationships. An experiment is an investigation in which a hypothesis is scientifically tested.

Type I and type II errors If we assert that the independent variable has an effect (we reject the null hypothesis and accept the research hypothesis) when in fact it does not, we commit an error. This is called a Type 1 error, and the probability of committing it is equal to the alpha level. However, we can make another kind of error.

Understanding psychological testing and assessment That's a bad idea, experts say. In fact, practicing ahead of time usually backfires — when you try to take the test in a certain way, the answers may be inconsistent and make you appear to have more problems than you actually do. Remember, psychological testing and assessment is nothing to fear. It's not something you need to study for. Rather, it's an opportunity for psychologists to determine the best way to help you. Thanks to Michelle F. Eabon, PhD, and Dan Abrahamson, PhD, for contributing to this article.

- In statistics, probable error defines the half-range of an interval about a central point for the distribution, such that half of the values from the distribution will lie within the interval and half outside.[1] Thus it is equivalent to half the interquartile range, or the median absolute deviation.

Research Methodology in Accounting 1 A Type II error occurs when the researcher fails to reject a null hypothesis that is false. 2  The probability of committing a Type II error is called Beta, and is often denoted by β. 3  The probability of not committing a Type II error is called the Power of the test.wo types of errors can result from a hypothesis test. 1  Type I error. 2  A Type I error occurs when the researcher rejects a null hypothesis when it is true. 3  The probability of committing a Type I error is called the significance level. 4  This probability is also called alpha, and is often denoted by α. 5  Type II error.

Descriptive/Correlational Research Descriptive/Correlational Research. Any scientific process begins with description, based on observation, of an event or events, from which theories may later be developed to explain the observations. In psychology, techniques used to describe behavior include case studies, surveys, naturalistic observation, interviews, and psychological tests. Case studies. A case study is a method of obtaining information from the detailed observation of an individual or individuals. Much information about behavior and mental processes has been obtained through such studies of individual clinical cases.

An Overview of Behavioral Psychology Operant conditioning (sometimes referred to as instrumental conditioning) is a method of learning that occurs through reinforcements and punishments. Through operant conditioning, an association is made between a behavior and a consequence for that behavior. When a desirable result follows an action, the behavior becomes more likely to occur again in the future.

Trial-and-error method Trial-and-error method. Trial-and-error (also known in computer science literature as generate-and-test model) is a method of problem solving based on experience with no explicit use of insight or theory building. Put simply, one selects a possible answer, applies it to the problem and, if it is not successful, generates another possibility that is subsequently tried.

Experimental psychology Experimental psychology refers to work done by those who apply experimental methods to psychological study and the processes that underlie it. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation & perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural substrates of all of these.

Science and Pseudoscience/research methods • Psychology is the scientific study of the mind, brain, and behavior. • Psychology is a science because it is an explanation for a large number of findings in the natural world. • It is challenging because it is complicated and it is full of scientific mysteries. (5 challenges) o Human behavior is difficult to predict → all actions are multiply determined: produced by many factors.

Measurement Error Random error is caused by any factors that randomly affect measurement of the variable across the sample. For instance, each person's mood can inflate or deflate their performance on any occasion. In a particular testing, some children may be feeling in a good mood and others may be depressed.
