6. HYPOTHESIS TESTING Hypothesis Hypothesis The, formulation of hypothesis reduces the problem to conditional relations which can be tested by the research process. The, formulation of hypothesis reduces the problem to conditional relations which can be tested by the research process. A hypothesis is a proposition that can be tested. It is an idea about the relation between two or more variables. A hypothesis is a proposition that can be tested. It is an idea about the relation between two or more variables. Hypothesis testing enables the researcher to compare theoretical results with those obtained by experimentation. Hypothesis testing enables the researcher to compare theoretical results with those obtained by experimentation. Gathering and analyzing data are ways of determining whether theoretical and experimental results are in agreement or whether the difference in results warrants rejection of the theory. Gathering and analyzing data are ways of determining whether theoretical and experimental results are in agreement or whether the difference in results warrants rejection of the theory.

7. The hypothesis can be tested in two forms: 1. Alternate hypothesis or Directional hypothesis The hypothesis can be tested in two forms: 1. Alternate hypothesis or Directional hypothesis 2. Null hypothesis 2. Null hypothesis Alternate hypothesis states that a difference does exist between variables. If a researcher has some evidence (personal observations or literature reports showing trends) to believe that one method is better than another, then a directional hypothesis can be tested. For example: dynamic exercises are better than isometric exercises for increase strength throughout the entire range of joint motion. Alternate hypothesis states that a difference does exist between variables. If a researcher has some evidence (personal observations or literature reports showing trends) to believe that one method is better than another, then a directional hypothesis can be tested. For example: dynamic exercises are better than isometric exercises for increase strength throughout the entire range of joint motion.

8. Null hypothesis states that no difference exists between variables. Null (means without value or significance). In hypothesis testing, the null hypothesis implies that the difference between the means of the different values is equal to zero. Null hypothesis states that no difference exists between variables. Null (means without value or significance). In hypothesis testing, the null hypothesis implies that the difference between the means of the different values is equal to zero. The null hypothesis is used commonly in experimental research because of simplicity. The null hypothesis is a clear and unambiguous statement. The null hypothesis is used commonly in experimental research because of simplicity. The null hypothesis is a clear and unambiguous statement. For example: ice packs and hot packs are equally effective for treating patients having chronic low back strains. For example: ice packs and hot packs are equally effective for treating patients having chronic low back strains.

9. LITERATURE REVIEW Related Research Related Research The most relative studies supporting the investigator's argument should be cited in this section. The most relative studies supporting the investigator's argument should be cited in this section. The investigator must present the information in a logical sequence, sometimes chronologically, to demonstrate his knowledge of previous research. The investigator must present the information in a logical sequence, sometimes chronologically, to demonstrate his knowledge of previous research. The story must convince the reviewer that previous research has not answered the question or tested the hypothesis stated by the investigator. The story must convince the reviewer that previous research has not answered the question or tested the hypothesis stated by the investigator.

10. If any current studies overlap the problem of the proposal, the investigator should show how this proposal differs from those studies or how it will complement them. If any current studies overlap the problem of the proposal, the investigator should show how this proposal differs from those studies or how it will complement them. A survey of literature relating to the problem must be undertaken. The reason for this are: A survey of literature relating to the problem must be undertaken. The reason for this are: 1. To ascertain originality of research. 1. To ascertain originality of research. 2. To provide ideas for solving the problem. 2. To provide ideas for solving the problem. 3.

The detail desired.

13. Personal Abstract File Isolation of each reference on a single index card or attached cards is important because as review of the literature continues, considerable information is available and collected. Isolation of each reference on a single index card or attached cards is important because as review of the literature continues, considerable information is available and collected. The researcher should choose the size of the card (7.6 x 12.7, 12.7 x 20.3 cm) on which to record bibliographical and abstract information and notes. The researcher should choose the size of the card (7.6 x 12.7, 12.7 x 20.3 cm) on which to record bibliographical and abstract information and notes. The abstract provides sufficient information to determine whether the report is relative to the research problem. The abstract provides sufficient information to determine whether the report is relative to the research problem.

14. Information Resources Abstracts Abstracts A number of journals provide readers with an abstracting services, which can save time in locating the original reports. Abstracts should be considered as secondary sources of literature review. A number of journals provide readers with an abstracting services, which can save time in locating the original reports.

16. Books Books Books on the most areas of interest are available in medical libraries. Books give basic material in varying degrees of depth according to the book's purpose, but not the most up-to-date sources of information. Their bibliographies offer important sources of information.
