PSY 225 Research Methods Spring 2013 Review Sheet Exam 1 CHAPTER 1 Why is the methods course believed to provide a “foundation” for other psychology courses? Hint: process vs. content. A methods course teaches a process (of doing research) that applies to other content courses. How do research psychologists use the terms determinism and objectivity? +Determinism= the idea that events‚ including psychological ones‚ have causes statistical determinism= events can be predicted‚ but only

Pilates Method for Lung Function and Functional Capacity in Obese Adults Joseph E. Mendoza Grand Canyon University BIO 201 Lab November 20‚ 2016 Pilates Method for Lung Function and Functional Capacity in Obese Adults Introduction Obesity is an extremely commonly condition in modern society. Obesity is defined as having a body mass index that is above 30 kg/m2. Obesity can affect the quality of life of an individual. It is estimated that about 2.8 million people die every year from causes

1. The first step in evaluating a regression model is to determine whether the sign of the estimated slope term makes sense. The second step is to test whether or not the slope term is significantly different from zero. The appropriate statistical test to determine this is a t-test since the true regression error variance is generally unknown. The third check of regression is to evaluate what percent of the variation in the dependent variable is explained by variation in the independent variable

The Scientific Method This experiment was performed by using a systematic approach to identify six unknown substances. In the first half of the experiment six unknown substances were observed than measured by determining volume‚ mass and density. The second half of the experiment the unknown were placed in a test tube and tested for solubility. It was determined that the six tubes contained coffee‚ potting soil‚ brown sugar‚ baby powder‚ baking soda‚ and powdered sugar. By the use of the scientific

The purpose of this research is exploration‚ description‚ explanation‚ and application. In the area of criminal justice things are getting researched all of the time. Take murder for example‚ the police have to explore to find out what actually happened. They have to describe the events leading up the the murder. They have to explain the facts to try and

Learning Goal: To understand how the scientific method can be used to search for explanations of nature. The scientific method is a procedure used to search for explanations of nature. The scientific method consists of making observations‚ formulating hypotheses‚ designing and carrying out experiments‚ and repeating this cycle. Observations can be either quantitative or qualitative. Quantitative observations are measurements consisting of both numbers and units‚ such as the observation that ice melts

(DPPH) for estimating antioxidant activity Songklanakarin J. Sci. Technol.‚ 2004‚ 26(2) : 211-219 The use of the stable free radical diphenylpicrylhydrazyl (DPPH) to estimate the activity of antioxidants is reviewed. Current applications of the method are examined‚ particularly the use of the parameter EC50 (substrate concentration to produce 50% reduction of the DPPH). Some recommendations are made as to the most suitable ways of carrying out this assay and evaluating the data produced. Key
