This section covers the following topics Requirements for a good experiment/study The types of research Statistical methods for combining research Section Summary Research forms the foundation of psychology; much of what we know about psychology today is because of research. There are specific requirements for research. A study or experiment must be both reliable and valid‚ and the procedure should be ethical according to the American Psychology Association’s standards.

subjects‚ I would go to several pediatrician offices and ask to use a total amount of 50 diagnosed hyperactive children for my experiment. With my newfound sampling‚ I create two groups‚ one being a control group of 25 children and the other being an experimental group of 25 children. To figure out how these children are put into which group‚ I use random assignment and randomly pick their names out of a jar. The independent variable‚ the factor that is being applied/tested and does not change‚ which

experiment during research. By changing the independent variable‚ and measuring the dependent variable‚ we control the confounding variables (E.V.s) others as much as possible. This allows a more reliable conclusion to be drawn up than with a non-experimental method. When the independent variable is the only variable that changes then it must be responsible for any change in the dependent variable. Milgram 1963 -Obedience.

HBS 2.2.3. Reaction Time Experimental Design I. Identify a Problem or Question: Can the reaction of an individual be affected by other external factors? II. Introduction: Reaction time refers to the amount of time it takes for a person to process and react to a stimulus. It is important in everyday activities‚ such as driving‚ and sports‚ but not much experiment is conducted to research on this matter. Reaction time with its practical implication can leads to great consequences‚e.g. d

Marcia Landell Applied Statistics Week 6: Analysis of Variance (ANOVA) Exercise 36 Analysis of Variance (ANOVA) I 1. A major significance is identifiable between the control group and the treatment group with the F value at 5% level of significance. The p value of 0.005 is less than 0.05 indicating that the control group and the treatment group are indeed different. Based on this fact‚ the null hypothesis is to be rejected. 2. Null hypothesis: The mean mobility scores for the control group and

EXERCISE 36 Questions to be Graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F (1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. Answer: The F value suggests there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05.This suggest that the groups are significantly

What is meant by double-blind‚ randomized controlled trial? Explain why such trials are used in psychological research with reference to one specific‚ published psychological experiment. Randomized controlled trials are considered the gold level standard of proof of many research techniques where treatments and therapies are concerned by the scientific community.
