Scientific inquiry and Hypothesis Testing

SCIENTIFIC INQUIRY STARTS WITH OBSERVATION. THE MORE ONE CAN SEE, THE MORE ONE CAN INVESTIGATE

Test may be called as a tool, a question, set of questions, and an examination which use to measure a particular characteristics of an individuals. Investigation, examination, inquiry, research express the idea of an active effort to find out something. But a test is a procedure intended to establish the quality, performance, or reliability of something it's like a trail or experiment. By this article I would like to present about simple discussion about scientific inquiry, reasoning and hypothesis testing. 

Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work.

Inquiry also refers to the activities of students in which they develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world. 

WHAT IS SCIENTIFIC INQUIRY?

Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work.

Models of scientific inquiry have two functions. First, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry succeeds as well as it appears to do in arriving at genuine knowledge. 

REASONING

Reasoning is the process of thinking about something in a logical way in order to form a conclusion or judgment. The ability of the mind to think and understand things in a logical way.

Inductive reasoning

Inductive reasoning, or inductive logic, is a type of reasoning that involves drawing a general conclusion from a set of specific observations. Some people think of inductive reasoning as “bottom-up” logic, because it involves widening specific premises out into broader generalizations.

Deductive Reasoning

Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements to reach a logical conclusion. Deductive reasoning goes in the same direction as that of the conditionals, and links premises with conclusions.

HYPOTHESIS TESTING

A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.

Hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.  A hypothesis is when you suppose something to be true before you know whether it is or not so that you can test it to see if it's true. 

IS THAT EARTH FLAT OR SPHERICAL?

Members of the Flat Earth Society claim to believe the Earth is flat. Walking around on the planet's surface, it looks and feels flat, so they deem all evidence to the contrary, such as satellite photos of Earth as a sphere, to be fabrications of a "round Earth conspiracy" orchestrated by NASA and other government agencies.

Without being in the sky, it is impossible to see the curvature of the Earth. However, you can always see a demonstration of this if you visit a harbor or any place with a wide-open view of the water. If you are able to watch a ship sail off to sea, watch its mast and flag as it fades off into the distance. You will notice that, in fact, it does not "fade off into the distance" at all; instead, you will see its mast and flag appear to slowly sink. The ship sailed beyond the point at which you would see it. 

It's as if you're watching it go over to the other side of a hill. This phenomenon can only be explained by a sphere-shaped planet.

Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data. The test provides evidence concerning the plausibility of the hypothesis, given the data.
