• CONCEPTUAL FRAME WORK-
• A conceptual framework is a written or visual representation of an expected relationship between variables. Variables are simply the characteristics or properties that you want to study. The conceptual framework is generally developed based on a literature review of existing studies and theories about the topic.
• HYPOTHESIS- a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
• "professional astronomers attacked him for popularizing an unconfirmed hypothesis".
• NULL HYPHOTHESIS- in a (statistical test) the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.

• ALTERNATIVE HYPHOTHESIS- an alternative hypothesis is one in which a difference (or an effect) between two or more variables is anticipated by the researchers; that is, the observed pattern of the data is not due to a chance occurance
