research hypothesis

1. Illustrate how to formulate research hypothesis Illustrate how to formulate research hypothesis TOPIC:

2. WHAT IS HYPOTHESIS? A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review.

3. WHAT IS RESEARCH HYPOTHESIS? A research hypothesis is a statement of expectation or prediction that will be tested by research. Before formulating your research hypothesis, read about the topic of interest to you.

4. How to write a hypothesis in 6 steps Ask a question. Conduct preliminary research. Formulate your hypothesis. Refine your hypothesis. Phrase your hypothesis in 3 ways. Write a null hypothesis.

5. How to Formulate an Effective Research Hypothesis. State the problem that you are trying to solve. Try to write the hypothesis as an if-then statement. Define the variables. Scrutinize the hypothesis Directional Hypothesis. Null Hypothesis.

6. Different types of research hypothesis are used in scientific research: Null hypothesis Alternative Hypothesis. Directional Hypothesis. Non-Directional Hypothesis. Simple Hypothesis. Complex Hypothesis. Associative Hypothesis. Casual Hypothesis.

7. Variable, it's Meaning and kinds A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

8. INDEPENDENT VARIABLE An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It's called “independent” because it's not influenced by any other variables in the study. Independent variables are also called: Explanatory variables (they explain an event or outcome)

9. DEPENDENT VARIABLE A dependent variable is what changes as a result of the independent variable manipulation in experiments. It's what you're interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)

10. CONTROLLED VARIABLE A control variable is any variable that's held constant in a research study. It's not a variable of interest in the study, but it's controlled because it could influence the outcomes.
