DESCRIPTIVE AND INFERENTIAL STATISTICS

Descriptive and Inferential Statistics Descriptive and inferential statistics are incredibly similar forms of research testing within psychology. Each seeks to analyze, describe, and possibly predict a population’s behavior. As with psychology itself, statistical analysis within psychology began as a philosophy (Goodwin, 2008). This philosophy quickly turned to a scientific pursuit, again mirroring psychology itself. A person observes, and wonders why that event occurred. That person makes a guess, known as forming a hypothesis, then he or she observes the situation again making small changes to test the theory. Once the determination that the behavior or occurrence is prevalent in a population for which the statistical study is relevant it is given a level of probability (A. Aron, E. Aron, & Coups, 2009). Statistics has two branches descriptive and inferential, and both branches use fundamental concepts as measurements of predictability. The predictability or probability of an event or behavior is determined through values, variables, and scores. Statistics would be redundant if data given by considerable surveys’ and testing were simple to interpret. However, the mass of information concerning a sample of a parameter used in inferential statistics, and a parameter used in descriptive statistics has become the easiest known way to interpret data (University of California, 1998). Expressed differently, raw data are difficult to visualize and translate into descriptive or inferential statistics (Leard Statistics, 2010). Properly interpreting data and graphing it in an easily understandable truthful manner is the major function in descriptive and inferential statistics. Descriptive Statistics Descriptive statistics summarize numbers in a set of data, such as mean or median, and values, or scores (A. Aron, E. Aron, &...

...Descriptive and InferentialStatistics
Statistical methods in psychology have two main branches, which are descriptive and inferential. They each play a major part in the data that is collected for research and other studies. This paper will show the functions of statistics, how descriptive and inferentialstatistics are defined and the relationship between the two....

...Descriptive & InferentialStatistics
The study of statistics plays a significant role in each of our lives. Statistics is a method often used in every scientific field to relay important information found, support new theories as they are developed and keep our society aware and up to date with the issues that affect us and what type of effect they have. From a psychological standpoint statistics...

According to Trochim, “Descriptivestatistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data” (Trochim, 2006). For many years, many studies and researches have been...

...DescriptiveStatistics is used when describing certain aspects of an immediate group within the population. For example, we may want to describe a math class and compare it to a class of science. Things that we may want to use for comparison would be age, gender, and even math skills. Descriptivestatistics would allow us to analyze all those different areas and provide a comparison to view similarities, differences and ratios. Before...
