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

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

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

student‚ such as high school graduation or grade promotion. Tests are called "standardized" when all students answer the same questions under similar conditions and their responses are scored in the same way. Research has shown that high-stakes testing causes damage to individual students and education. It is not a reasonable method for improving schools. Test-taking anxiety is common among high school and college students. The anxiety can be quite stressful and

Mandatory Drug Testing for Welfare Recipients Introduction Mandatory drug testing for welfare recipients is a controversial issue. Should the government hold people accepting government entitlement’s accountable for illegal drug use or would this type of action cross the boundary of civil liberties into an invasion of privacy? The government has a vested interest in getting welfare recipients back into the working population. Holding welfare recipients accountable for illicit drug use only

Is standardized testing the way to go? You wake up in the morning belated for the bus because of sleeping late. You arrive in school‚ forgetting to brush your teeth and comb your hair.

Standardized testing may cause you to stay in the same grade just for having an inadequate day‚ not getting enough sleep‚ etc
