What is a simple hypothesis?
Simple hypotheses are ones which give probabilities to potential observations. The contrast here is with complex hypotheses, also known as models, which are sets of simple hypotheses such that knowing that some member of the set is true (but not which) is insufficient to specify probabilities of data points.

What is hypothesis give example?
Professionals typically write hypotheses as if/then statements, such as if someone eats a lot of sugar, then they will develop cavities in their teeth. These statements identify specific variables and propose results. In this example, the variable is the amount of sugar and the result is developing cavities.
What is a hypothesis in science?
A hypothesis is an idea or proposition that can be tested by observations or experiments, about the natural world. In order to be considered scientific, hypotheses are subject to scientific evaluation and must be falsifiable, which means that they are worded in such a way that they can be proven to be incorrect.

A good hypothesis has variables and is testable. Variables can be measured and changed by the experimenter. A testable experiment tells us if our hypothesis was correct.
What is a better hypothesis?
Generally, a good hypothesis: is testable, meaning it must be possible to show that a hypothesis is true or false, and the results of this investigation have to be replicable; includes both an independent and dependent variable. allows for the manipulation of the variables ethically.
