In order for a hypothesis to be sound, hold tight to these tips:

An early focus of expert system development was on applications involving inferencing or diagnosis from a set of observed facts to arrive at a more general assessment of the situation that concisely "explains" those observed facts. Consequently, there has been interest in using expert systems to implement situation awareness models.

Presentation aids can fulfill several functions: they can serve to improve your audience’s understanding of the information you are conveying, enhance audience memory and retention of the message, add variety and interest to your speech, and enhance your credibility as a speaker. Let’s examine each of these functions.

The old saying “You never get a second chance to make a first impression” points to the fact that first impressions matter. The brain is a predictive organ in that it wants to know, based on previous experiences and patterns, what to expect next, and first impressions function to fill this need, allowing us to determine how we will proceed with an interaction after only a quick assessment of the person with whom we are interacting. Research shows that people are surprisingly good at making accurate first impressions about how an interaction will unfold and at identifying personality characteristics of people they do not know. Studies show that people are generally able to predict how another person will behave toward them based on an initial interaction. People’s accuracy and ability to predict interaction based on first impressions vary, but people with high accuracy are typically socially skilled and popular and have less loneliness, anxiety, and depression; more satisfying relationships; and more senior positions and higher salaries. So not only do first impressions matter, but having the ability to form accurate first impressions seems to correlate to many other positive characteristics.

A statistical hypothesis is an examination of a portion of a population.

This is where the alternative hypothesis (H1) enters the scene. In an attempt to disprove a null hypothesis, researchers will seek to discover an alternative hypothesis.

Make sure your hypothesis is testable with research and experimentation.

Either a neuron completely fires or it does not fire at all.

People are astonishingly open and cooperative when approached in an interested, supportive, and nondemeaning way. Too often, however, psychologists have impersonally handed out highly personal questionnaires for reasons not appreciated or believed by the recipients. It is not surprising, under such circumstances, that deliberate innocuity of response has been and often still is the order of the day. Indeed, failure to cover up and appear blandly conventional in such settings appears to be a sign of psychopathology. But in the context of seeking psychiatric help, it is far less likely that someone will dissimulate in his responses to an inventory. In any event, many questionnaires incorporate items which, separately or in conjunction, provide an indication of the frankness of the respondent and hence of the validity of his responses. There have been increasingly successful attempts to construct questions or combinations of questions the full implications of which almost no respondent could be expected to understand.
