The split-half method assesses the internal consistency of a test, such as psychometric tests and questionnaires. When the selection of the participants happens under bias, the ability for the study's outcomes to be generalized amongst a population becomes disabled. If the two halves of the test provide similar results, this would suggest that the test has internal reliability. Advantages: Can test large amounts of content True-false are adaptable to the measurement of a wide variety of learning outcomes Quick and easy to grade If constructed well, can be highly reliable in assessing student knowledge Disadvantages: It is difficult to discriminate between students that know the material and students who do not For example, if a person weighs themselves during the day, they would expect to see a similar reading.

There, it measures the extent to which all parts of the test contribute equally to what is being measured. That is why people prefer such methods in which only one administration of the test is required. In this method two parallel or equivalent forms of a test are used. Within qualitative research methods, validity and reliability can be determined through the consistency and objectives of the data outcomes, participants, types of tests, and researcher observations. One of the most important forms when measuring validity is construct validity. measures the degree of agreement between different people observing or assessing the same thing. The studies completed with the different age groups showed that the reliability of the different subtests was largely within the moderate to high range. 2.) You use it when data is collected by researchers assigning ratings, scores or categories to one or more variables. Questions asked about method error include: Is the experimenter using the tool of measurement correctly? The resulting test scores arc correlated and this correlation coefficient provides a measure of stability, that is, it indicates how stable the test results are over a period of time.
