Refer to Ch. 4 and 5 of Beginning Behavioral Research and
address each of the following points:
o Define and describe the types of reliability. Provide examples of these types of reliability as they apply to human services research or to human services management research.
o Define and describe the types of validity. Provide examples of these types of validity as they apply to human services research or to human services management research.
o Provide examples of a data collection method and data collection instrument used in human services research. Why is it important to ensure that these data collection methods and instruments are both reliable and valid?

In the field of Human Services, especially in the creation of programs, projects and approach strategies, it is important to measure the reliability of approaches and results. The following approaches are more often than not used to test reliability and are therefore the embodiment 'types' of how reliable an approach or strategy tested with them is:
1.Test-retest reliability - The test-retest method estimates the reliability of the test and the results gathered from it by administering the test to the same group of people at least twice over a set period. The results are then correlated and with high reliability mark, the tests are seen as reliable.
2.Alternate Forms - Two groups are given the test and their scores are correlated. They do not necessarily have to come from the same population (i.e. test in India & test in Bangladesh) as long as there is a certain relationship. The score correlation becomes the reliability guide.
3.Split Half reliability - In terms of tests, half the items relate to the other half and it is the correlation between them in the test results that matter (i.e. half ...
The solution is a 741-word essay divided into 3 sections. Section one provides a description of the varied types of reliability in research (i.e. human services management research), section 2 discusses what validity is about, its different types (or the different means of approaches that validate data/conclusion in research and section 3 presents the types of data collection methods usually used in research. References are included for expansion. A word version of the solution is attached for easy printing.
