WHAT IS HYPOTHESIS ? IT IS A PREDICTION. A TENTATIVE STATEMENT. THE VALIDITY IS NOT KNOWN. LOGICAL RELATIONSHIP BETWEEN TWO VARIABLES. CAPABLE OF BEING TESTED BY SCIENTIFIC METHODS. IT MUST BE GENERALIZABLE. SIMPLE AND CLEAR.
. FORMULATION OF HYPOTHESIS IS A PART OF RESEARCH BUT NOT NECESSARY FOR ALL TYPES OF RESEARCH.
Characteristics of a hypothesis Hypothesis should be clear and precise tested Hypothesis should be able to relate to a . Hypothesis should be capable of being variable.
Characteristics of a hypothesis e Hypothesis must be limited in scope and must be specific Hypothesis must be stated in very simple terms Hypothesis must be consistent with most known facts
Characteristics of a hypothesis e Hypothesis must be testable within a reasonable time Hypothesis must explain the facts which most need explaining
FUNCTIONS OF HYPOTHESIS THEY BRING FOCUS,CLARITY AND SPECIFICITY IN STUDY. IT HELPS IN MAKING SIMPLE DESIGN. THEY MAKE THE STUDY MORE OBJECTIVE. THEY FACILITATE THE FORMULATION OF THEORY.
Basic concepts concerning testing of hypothesis Null Hypothesis and alternative hypothesis In statistical analysis if we want to compare method A with method B and if we proceed with the assumption that both methods are equally good then this assumption is termed as null hypothesis.
NULL HYPOTHESIS NULL HYPOTHESIS simply means "NO DIFFERENCE -The hypothesis says that OBSERVED DIFFERENCE IS ENTIRELY DUETO SAMPLING ERROR i.e. it occurred purely by chance. It is denoted by Ho.
Basic concepts concerning testing of hypothesis Null Hypothesis is generally is termed as Ho and alternative hypothesis symbolized as Ha
Basic concepts concerning testing of hypothesis The null hypothesis, HO represents a theory that has been put forward, either because it is believed to be true or because it is to be used as a basis for argument, but has not been proved
