HYPOTHESIS TESTING WHAT IS THIS HYPOTHESIS???? • In simple words it means a mere assumption or supposition to be proved of disproved. • But‚ for a researcher it is a formal question that he intends to resolve. • Example: I assume that 1) under stress and anxiety a person goes into depression. 2) It leads to aggressive behaviour. Eg. : Students who get better counselling in a university will show a greater increase in creativity than students who were not counselled. • So‚ the hypothesis

The word ‘Hypothesis is derived from a Greek word‚ which means ‘to suppose’. It is usually considered as the principal instrument in research. For a researcher it is a formal question that he or she intends to resolve. In this way a hypothesis may be defined as a proposition or a supposition. The main function of hypothesis is to guide the collection and processing of materials and direct the research. Hypothesis is a tentative conclusion. It is facts based theory. A research scholar will analyze

Two Parents Or One? Family life is much different today than what it used to be. Several years ago mothers would stay at home with their children while the father went to work to support his family‚ but it is nothing like that today in American households. Today it is common for children to be raised by just one of their parents‚ and those children are often disadvantaged in several ways. The most consistent finding from studies of family structure shows that single parents exert weaker

Hypothesis Testing: Two-Sample Case for the Mean Many cases in the social sciences involve a hypothesis about the difference between two groups (i.e. men and women‚ control and experiment). We analyze statistics from two samples‚ and the hypothesis and confidence interval would deal with the difference between two population means. The following factors are important in hypothesis testing: 1. probability theory 2. the sampling distribution of the statistic 3. the errors inherent

step 2: The hypothesis Answer the following questions: * What is a hypothesis? * How is a hypothesis different from a theory in science? * Describe an example of how you may use the scientific method in your daily life and state a good hypothesis for that example. * Which hypothesis did you first pick in the "Recognizing a good hypothesis" activity in the scientific method tutorial? Why? If any‚ which mistake(s) did you make when picking a hypothesis? A hypothesis is a specific

RESEARCH METHODOLOGY LESSON 20: PRINCIPLE OF HYPOTHESIS TESTING So far we have talked about estimating a confidence interval along with the probability (the confidence level) that the true population statistic lies within this interval under repeated sampling. We now examine the principles of statistical inference to hypotheses testing. By the end of this chapter you should be able to • Understand what is hypothesis testing • Examine issues relating to the determination of level of How is this

Aaron Almonte One Brain or Two? Numerous researches and experiments have been done based on whether the human being possess one brain divided into two parts (left and right hemisphere) or whether we have two different brains working together. The psychologist Roger W. Sperry was the first on research this topic with some experiments on animals. Then‚ he later started working with Michael Gazzaniga. They were able to find split-brain patients. Those patients had their brain split as way
