Research than some guess but less than a

Research experiments are crucial for science because research experiments help us to prove our hypothesis or they say your hypothesis is wrong and that help us to improve science and in the and improve our daily lives. About the structure of a research experiment, research experiment needs a hypothesis, independent variable, dependent variable, control group, experimental group, random assignment. A hypothesis is an idea or explanation that you then test through study and experimentation. A hypothesis is something more than some guess but less than a good thinking theory. If we are going to do research experiment, first of all, we need a hypothesis because it’s the roots of an experiment we will research the hypothesis is true or not. Purpose of the hypothesis is when you are going to research something, you need to say something like that ” “if A happens, then B will be the result.” you need to be specific because it is your idea and you will research that idea.About independent variable,  an experimental variable controlled and manipulated by the experimenter.A dependent variable is a variable being tested and measured in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable. If the experimenter changes the independent variable it effects the dependent variable. Basically the “result” part of a hypothesis.About control group and experimental group. Control group is a group separated from the rest of the experiment such that the independent variables being tested cannot influence the results. Because we need to learn the what happens in the normal conditions, without the independent variables.An experimental group is a group of participants that is exposed to the independent variable. After that, we can see clearly the difference between two groups and we can examine them.Random assignment means in experiments using randomization, such as by a chance procedure like, for an example if we have 20 participants in our research experiment and if we need to separate two groups, control and experimental, we can use flip a coin technique and  in the end experimenter find the difference between control and experimental group because everyone has an equal chance to being placed in a group.
