Use of Statistics in Research

Research in the field of psychology is highly important as this is what evolves the field to be ever so large. The use of statistics within research needs to be done correctly with the highest logical and ethical way possible. When looking at research and the research results, the reliability and validity question typically come. How does one know a test is reliable or valid? This is all highly important in the field when using statistics and research to provide information. Statistical concepts can help aid the researcher successful results and substantiate the research, hence the point of reliability and validity (Stangor, 2011). With any concept, there are strengths and weaknesses that are important and some can be difficult to dissect and understand.                                                                                                                        One concept that is interesting is random errors. There are several ways in which an error can occur in testing, anything from: the participant not understanding, marking the wrong question in a test or study, an individual surveying the results and accidentally makes a data entry error, and several other minute factors. It is interesting because it makes one wonder how valid the results are. If there was a small error, it could mean a difference of an entirely different outcome.
