Hypotheses Prepared By T.Manoj Kumar Assistant Professor
Hypotheses Hypotheses Definition “ It could be a tentative solution to a problem of the researcher or a tentative answer to a researcher’s question to be verified by appropriate means
Hypotheses Sources of Hypotheses 1. Theory 2. Observations 3. Intuition and Personal Experience 4. Analogies 5. Review of Literature 6. General Culture
Hypotheses Steps in Hypothesis Testing Step 1 :State the null and alternative hypotheses Step 2: Choose the appropriate statistical test (Z,t,f,chi-square or ANOVA is selected depending on the problem) Step 3: Determine the level of significance(10% or 5% or 2.5% or 1%).The most common value is 5% (0.05) Step 4: Compute the calculated value by using formula of the appropriate test (formula of Z test or t test or f test or chi-square test or ANOVA test) Step 5 : Obtain the critical value from the table. Step 6 : Compare the calculated value and critical value (table value). If the calculated value is > than the table value, reject the null hypothesis If the calculated value < than table, accept the null hypothesis & reject the alternate hypothesis
Hypotheses Characteristic of a Good Hypothesis 1. A hypothesis must be expressed in simple language without any ambiguity in meaning 2. It must be specific and precise without creating any confusion 3. It must be amenable for testing with empirical data 4. It must be testable within reasonable time. 5. In the case of relationship hypothesis, the relationship between the variables must be stated 6. It must provide an answer to the problem which helps to investigate the research in a particular direction.
