Question Answered step-by-step The scientific method is a process that scientists use to better… The scientific method is a process that scientists use to better understand the world around us. This includes making observations and asking a question, forming a hypothesis, designing an experiment, collecting and analyzing data, and drawing a conclusion. This sometimes also is referred to as scientific inquiry. A hypothesis is a possible explanation for an observation. A good scientist will design a controlled experiment to test their hypothesis. In a controlled experiment, only one variable is tested at a time. This is called the manipulated or independent variable. The experimental group will test the independent variable. The control group is left alone, so you have something to compare your results to. The variable that determines the data is the responding, or dependent variable. It responds to the manipulated variable. All other variables in the experiment remain the same, otherwise, if you change more than one variable, you will not now which variable explained your results. Once may different scientists have tested something many times, it can become a scientific theory. It is different from a scientific law, which describes what will happen every time under a particular set of conditions. More about ObservationsObservations are either quantitative or qualitative. Quantitative data are an objective collection of data primarily focused on numbers and values. This type of data suggests “associated to, of or depicted in terms of a quantity.” Results of quantitative observation are derived using statistical and numerical analysis methods. Quantitative observations are invariable, accurate, measurable and can be recorded in terms of numbers.Qualitative data is that which is observed with our senses: sight, smell, touch, taste, and hearing. They do not involve measurements or numbers. For instance, colors, shapes and textures of objects all are qualitative observations. Qualitative observations are variable, not accurate, not measurable and cannot be recorded in terms of numbers. Biology Science Nutrition NUTR 101 Share QuestionEmailCopy link Comments (0)
