Caterpillar has been researching the idea of replacing the traditional steering mechanism on its graders with a joystick based s

Wanda makes an educated and accurate guess about her friends' behavior in a specific situation. in other words, she is making a hypothesis.

<h3 /><h3>What is a hypothesis?</h3>

It corresponds to an assumption that generates a statement that is deduced through a set of data and information, which is an integral part of scientific studies, which should be the basis for the research question that must be resolved at the end of the study, through the method of qualitative and quantitative data collection and of the experiments that will be carried out.

A hypothesis is a statement that may involve a series of biases, and cannot in fact be judged to be true until proven through the scientific method.

Therefore, hypotheses tested through science can increase understanding of a topic, whether their assumptions are true or false, generating greater reliability about an idea.
