Usage of Statistical Principles in Psychological Research

Statistics stands out as the name for methods or guidelines concerning the management and interpretation of quantitative information from a study (MCREL, 2004). This essay seeks to explore the use of statistical concepts in psychological studies and analyze a research article from a professional counseling journal that employs statistical methods and concepts.

Research Making use of Statistical Techniques and Principles.

A research in 2002 referred to as Asperger Syndrome and Academic Achievement and done by Deborah E. Griswold, Gena P. Barnhill, Brenda Smith Myles, Taku Hagiwara and Richard L. Simpson, employed statistical assessment to achieve its pursuits. Twenty-one young children having diagnoses associated with AS were evaluated making use of the Wechsler Individual Achievement Test (WIAT), the Test of Problem Solving-Elementary, Revised (TOPS-R), as well as the Test of Problem Solving- Adolescent (TOPS-A) (Griswold, Barnhill, Myles, Hagiwara & Simpson, 2002).

Three Statistical Principles Which Are Essential In an Article and Their Suitability

The sampling Method.

Twenty-one youngsters having Asperger syndrome took part in the research. All participants were living in a big Midwestern neighborhood within the

United States of America. Nineteen males and 2 females who ranged in their age from 6 years 9 months to 16 years 8 months concluded the WIAT, TOPS-R, as well as TOPS-A tests. School positioning were diverse with 6 (28%) learners getting their schooling in standard classroom surroundings, 14 (67%) in standard schooling settings having resource room services, and additionally 1 (5%) within self-contained special schooling.

All individuals were White and previously had been clinically determined by a licensed professional as going through AS according to DSM-IV specifications. The research participants possessed Verbal IQ ratings which ranged from 55 to 146 (Griswold, Barnhill, Myles, Hagiwara & Simpson, 2002). The sampling technique is actually essential since the sizeable samples, arbitrary selection as well as a varied representation helps to ensure that there won't be any type I or type II errors, the actual statistical strength is enhanced and it shows superb population estimation (Anon, n.d.).

The Mean. The mean stands out as the average amount in any frequency distribution. The report in focus employed the mean to provide the typical score (Griswold, Barnhill, Myles, Hagiwara & Simpson, 2002; MCREL, 2004).

The Standard Deviation. The stands out as the method of calculating the specific variability for the outcomes inside a several outcomes or simply a frequency distribution, much like the basic range of the outcomes from the mean (MCREL, 2004). The report under attention employed the standard deviation to provide the range for scores from the study's average scores by participants in various tests (Griswold, Barnhill, Myles, Hagiwara & Simpson, 2002).

Ethical Matters in Research

The researchers need to abide by the ACA Code of Ethics on Research and Publication within their undertaking of the study as well as in their particular interpretation or use of study results (ACA, 2005).

Conclusion

The article examined portrayed appropriate employment of standard deviation, sampling, and mean in statistical analysis of the results. In Psychology, it is important that the researchers abide by the ACA Code of Ethics on Research and Publication when accomplishing the research as well as within their interpretation/application of study results.
