Reliability in psychology

In psychological research, reliability is the consistency of a research study or measuring test. A good

example is when one buy a bottle of soda he or she expect that the same quantity will be even if he or

she will buy such a bottle after a period of like 5 or so years. In case there be a slight change, the one

buying may not be in a position to notice since he or she may have taken it as normal and as the way it

should be.

This reliability also takes part in scientific research where some of the input are hold constant

throughout the research period.

In psychology, reliability is grouped in two types which are internal and external reliability.

Internal reliability mostly deals with items which are within the test that is being performed these can

be like one’s character while external reliability mostly relate internal and external items within the

research. It can also be between two or more people. Below are some of the methods used in reliability

research;

Split-half method. It mostly asses internal consistency of the test. A test to be done is divided in to many

halves and a conclusion is made after comparing results of two halves. One of the areas where this

method is mostly applicable is in a science lab where properties of a chemical are to be determined

through a chemical test. A small portion may be taken and be used in all the test and from it a

conclusion of the whole chemical is made.

Test retest method. It mostly focus on external consistency of a test. In this participant are given same

test at different places and results are compared. A good example is two programmers are given a case

and are requested to come up with a program to solve a similar problem. One programmer may wish to

use a programming language which is different from the other programmer but the result be the same.
