Advantages of the use of the scientific method in psychology There are a number of advantages to using scientific methods in psychology. Firstly an important aspect of imperial data is that it is objective‚ i.e. not affected by expectations of the research. So‚ without objectivity we have no way of being certain that data collected is valid. An example of this is seen with Gardner & Gardner. When they observed Washoe they might have judged that Washoe was using real words because they wanted

Introduction and background information: Digital forensics is a branch of forensic science involving the recovery and investigation of material found in digital devices used in crimes or by criminals. In the past 15 years it has expanded greatly with all the advances in technology but much of the new technology has not been studied yet. The research I am doing is important because if the study is successful in the future many forensic departments could use my research to solve crimes. Key terms: Jump

1. INTRODUCTION Forensic science is the application of scientific procedures to help solve criminal and legal matters. At the scene of any crime a variety of physical evidence may be left behind that can link a criminal to a crime‚ or help reconstruct the sequence of events which occurred during that crime. Forensic biologists examine articles and crime scenes for evidence of biological material and attempt to determine the origin of that material by using tests that provides biologically discrimination

After three months of expert investigation it was found that the DNA evidence that was discovered at the scene did not belong to Jennifer or Noura. Also Noura’s own DNA was not found at all at the scene of the crime. It is very hard to understand how Noura could have made extreme violent contact with her mother and not left any fingerprints‚ footprints‚ hair‚ skin cells‚ blood‚ bodily fluids‚ pieces of clothing or fibers behind. This lack of traces evidence sets off two different paths in my mind

You can gather your data at work‚ on the phone‚ or via some other method. This is your “Sampling Design.” Which of the four sampling techniques best describes your design? 5. Explain in moderate detail the method you used to gather your data. In statistics this venture is called the “Methodology.” 6. Make sure you break your sample into classes or groups‚ such as males/females‚ or ages‚ or time of day‚ etc. 7. Calculate the mean‚ median‚ and mode for your data as a whole. 8. Now calculate the
