BIT 323 CAT-DATA ANALYSIS TECHNIQUES SIT/0006/10 Assignment 1 Types of Hypotheses There are two types of hypotheses: i. Research hypothesis ii. Null hypothesis. Research hypothesis It is the hypothesis derived from the researcher’s theory about some social phenomenon. Researchers always believe that their research hypotheses are accurate statements about the condition of the things that they are investigating. They believe that their hypotheses are true to the extent that the theory from which they were derived is adequate. However, the theories are only suppositions about the true nature of things, and, thus, hypotheses derived from theories must also be regarded as just tentative suppositions about things until they have been tested. Testing hypotheses means subjecting them to confirmation or disconfirmation. Null hypothesis It is the opposite of research hypothesis. It is also a statement about the reality of things, except that it serves to deny what is explicitly indicated in a given research hypothesis. For example, if the research hypothesis states that “the mean age of BSc. Information Technology students is 22”, a null hypothesis derived from it would be “the mean age of BSc. Information Technology students is not 22”. If the researcher can demonstrate that the mean age of the BSc.IT students is at 22, then the null hypothesis is refuted. If the null hypothesis is rejected, then logically the statement that “the mean age of BSc. IT students is 22” is supported. It can be seen tha
