understanding of hypothesis testing. The textbook explained the aspects and steps of hypothesis testing in a legible fashion‚ while the video helped demonstrate a real-life application. I learned from the text that hypothesis testing is a “Procedure for deciding whether the outcome of a study (results from a sample) supports a particular theory or practical innovation (which is thought to apply to a population)” (Aron A.‚ Aron‚ E.‚ and Coups‚ 2011‚ p. 145).

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.

Hypothesis Testing The sole purpose of hypothesis testing is to determine whether or not research that has been collected is proved or disproved; usually allowing up to a 5% error factor. By using this 5% margin of error a researcher can consider the question of research being conducted is proven. There are five steps to be followed in doing hypotheses testing. The steps are: developing the research question‚ specifying between null and alternative hypotheses‚ calculating the statistic‚ computing
