Mean: The average of a distribution; Found by adding all scores then dividing by the quantity of scores. This relates to psychology as most studies and or experiments will show their data in numbers and most often include a mean.

Standard Deviation is a statistic that is calculated by as the square root of a variance, or a data set calculated by taking the mean (average) of the squared differences between each value and the mean value.

Theory a supposition or a system of ideas intended to explain something,especially one based on general principles independent of the thing to be explained. A psychological theory has two key comments it must describe a behavior and make predictions about future behaviors. psychology.about.com/od/tindex/f/theory.htm

Informed consent- A legal procedure to ensure a patient, client, and research participant, etc aware of risks and costs involving their treatment or procedure. Also informing that client of their nature of the procedure, alternate treatments, potential risks and benefits of the treatment.

Hindsight Bias - After an event or in this case after experiments have occurred, one sees the event as being predictable, regardless if there was an objective.

Placebo effect- The phenomenon in which some people experience some type of benefit after being administered a placebo.

Control group- a group of people not affected by the independent variable. These groups can be negative or positive. They are often given a placebo. This relates to psychology because when conducting an experiment this group helps isolate the independent variable effects.

Experiment-a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.It relates to psychology because it is one type of research method in which the investigator manipulates one or more independent variables to determine the effects on some behavior while controlling other relevant factors

Scatterplot - A scatterplot or scatter diagram is a graph where two variables are plotted along two different axises to show the correlation or pattern between the two.

Replication is the repetition of a research study. With different situations and different subjects, it is used to determine if the basic findings of the original study can be applied to other patients and situations.

Correlation - A measurement of the relationship between two variables. This could be positive (both variables show that as one increases, the other increases), negative (both variables show that as one decreases, the other decreases), or there could be no correlation between the two variables.

Double-Blind Procedure: an experimental procedure in which neither the subjects of the experiment nor the persons administering the experiment know the critical aspects of the experiment; "a double-blind procedure is used to guard against both experimenter bias and placebo effects"

Statistical Significance- A result that isn't likely to occur randomly, but rather is likely to be attributable to a specific cause. It is important to research in a lot of math- and science-related fields, including medicine, sociology, psychology and biology.

Correlation coefficients measure the strength of association between two variables. The most common correlation coefficient, called the Pearson product-moment correlation coefficient, measures the strength of the linear association between variables. Above is a website of a picture showing linear correlation coefficients.

random assignment in when psychologist preforming an experiment use a random selection of people to make sure there is no bias in the study. it includes flipping a coin or drawing a name from a hat.

A Confounding Variable is an irrelevant variable whose presence affects the variables being studied so that the results you get do not reflect the actual relationship between the variables under investigation

An experimental group in a scientific experiment is the group where the experimental procedures are performed.
