EVERYDAY SCIENCE

Detailed explanation-1: -How are hypotheses tested? When possible, scientists test their hypotheses using controlled experiments. A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant.

Detailed explanation-2: -The scientific method can only be used for testable phenomenon. This is known as falsifiability. While much in nature can be tested and measured, some areas of human experience are beyond objective observation. Both proving and disproving the hypothesis are equally valid outcomes of testing.

Detailed explanation-3: -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.

Detailed explanation-4: -In this article we describe hypothesis testing, which is the process of drawing conclusions on the basis of statistical testing of collected data, and the specific approach used to test means (or average levels of a collected data element).
