ommon sense can tell us the results of the study before the study even begins. It is the hypothesis of an indissoluble association between two or more events, assumed without verification, without criticism. }, tcData.listenerId); But when you’re holding an experiment, it’s even more important that your guesses be good...after all, you’re spending time (and maybe money!)

Statistically, it's easier to show there is no relationship between two variables than to support their connection. Create an account to start this course today. Does your hypothesis include both an independent and dependent variable? Monitoring how often someone smiles for a whole day is not reasonably observable, but having the participants state how happy they feel on a scale of one to ten is more observable.

Descriptive research such as case studies, naturalistic observations, and surveys are often used when it would be impossible or difficult to conduct an experiment. These methods are best used to describe different aspects of a behavior or psychological phenomenon. In this case, this is a null hypothesis because it’s asking the opposite of the original thesis! Hypothesis is defined as “a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation” in the Oxford dictionary and as “an idea or theory that is not proven but that leads to further study or discussion” in the Merriam-Webster dictionary.
