Descriptive and Inferential Statistics Paper
Statistics are used for descriptive purposes, and can be helpful in understanding a large amount of information, such as crime rates. Using statistics to record and analyze information, helps to solve problems, back up the solution to the problems, and eliminate some of the guess work. In Psychology there has to be a variable or variables to be organized, measured, and expressed as quantities. Information is usually in the form of a frequency table, histogram, or bar graph to show the increase or decline in occurrences over a period of time. Psychological statistics is used to keep track of behavioral reactions to certain stimuli, and since the human behavior is so unpredictable, psychologists use statistics instead of trying to predict outcomes of situations. Functions of Statistics

Understanding and interpreting data can be difficult if one does not possess the necessary skills to do so. The knowledge of how and why statistics are used is a very important first step to gaining these skills. The following few paragraphs will offer an explanation of the functions of statistics, which will describe how different types of statistics are used to make sense of data that can sometimes be confusing. Both descriptive and inferential statistics serve the same basic functions. The main functions of statistics are to organize and interpret data and to allow one to form hypotheses (Weinclaw, 2008). Statistics help to make sense of data by allowing one to organize and manipulate the data to come to a conclusion. This allows people to gain a better, although not perfect, understanding of phenomena occurring in the real world. Instead of yielding exact results statistics provide probabilities, which allow one to make generalizations about a whole population based on data gathered through surveys or samples of a population. Thus statistics are used to suggest a degree of...

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...

...Association [ASA], 2008). Statistics is a division of mathematics that centers on the collection and evaluation of data, which can be drawn upon to make conclusions (Aron, Aron, & Coups, 2006, 2). Two branches of statistics exist, including descriptive and inferential domains. Extrapolation beyond the data is where the real difference emerges. Indeed, these two subcategories vary in function and definition. However, a relationship exists between...

Measuring productivity is paramount for the successful organization; in terms of profitability and progressively growing the business. The data was significantly skewed. Fifty five subjects were randomly selected. Their ages were between 19 and 55 years, with a mean of 37.84, mean of 41 and standard deviation of 9.11....

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 inferential statistics are defined and the relationship between the two.
