The Importance of Statistics in Academic Research: A Comprehensive Guide for Students

1. Introduction to Statistics

A survey of Virginia Tech students from Fall 2002 to Spring 2005 showed that approximately 5,500 students enrolled in the introductory or “applied” statistics and probability course offered by the Department of Statistics. An additional 305 students received two credits for the honors section of the course. In addition to the non-honors and honors version of the probability and statistics course, 49 other departments offered a total of 60 unique courses with special emphasis on statistics. Only six departments offered one to two courses with basic statistical content, but 30 departments offered 53 other courses as electives or specialized courses at the introductory and intermediate level. Most of the remaining courses were at the advanced level and specialized content was found in 25 areas.

Statistics involve an array of methodologies for many academic disciplines. In 2012, statistics crossed an important threshold as the number of statistics and biostatistics bachelor’s degrees awarded in the United States more than doubled in the previous decade to reach 10,000 and 5,000 per year, respectively. Much of this growth can be attributed to the fact that statistics has become a key tool in diverse fields, as students realize the importance of statistical techniques and applications in their own disciplines. In 2005, the American Statistical Association (ASA) endorsed a set of important and useful recommendations for undergraduate courses in statistics, emphasizing the desirability of integrating statistical thinking and reasoning into courses across the entire undergraduate curriculum. In 2009, the major educational goals of an introduction to statistical reasoning for college students were refined and endorsed by 24 professional societies.

2. Key Concepts and Terminology in Statistics

In this sense, statistics is the art and science of discovering answers based on data. It involves the formulation of a research question, imagining ways to answer the question, collecting and summarizing quantitative data about possible answers, and interpreting and drawing inferences about that data. Here we provide an overview of research methods and statistics at the undergraduate level, especially for aspiring doctoral students, by introducing a series of key statistical concepts and terminologies. We focus on simple statistics topics such as distributions, mean, median, variance, hypotheses testing, and conceptual questions. Keep in mind that this is just one approach to statistics at an advanced undergraduate level, and that there are many other approaches with different types of methods and concepts. This ‘quick reading’ can provide a foundation for more formal learning in the form of college-level coursework that emphasizes practical project-based training. Preparing for this type of course organization can help people interested in acquiring the necessary skills to efficiently carry out research projects and truly understand the implications of the use of statistics in the formal development of research methods. Remember that people will learn different topics deeply at different stages, and will not master everything.

2.2 Sample A sample is a subset of a population. It is a representative of a larger group based on a specific characteristic. The sample size (n) is the number of subjects in the sample.

2.1 Population The population includes all subjects we are interested in studying. It often includes all persons, or subjects that share at least one specific characteristic.

Statistical analysis is a method of collecting data to uncover relationships. It involves a procedure for collecting, summarizing, and interpreting data. Statistics is also a method of drawing inferences about the properties of a population or the parameters of a probability distribution from those of samples. The concept of probability is important in statistics, as is statistical computing for data. The methodology used in statistics is applicable to a wide range of areas. As disciplines, statistics and probability have a history that is centuries long and have developed many sophisticated methods for the interpretation of data. In the first part of this article, we will revisit some key concepts and the terminology used in statistics.

3. Types of Statistical Analysis

The first type, descriptive statistics, refers to techniques used to summarize features of the dataset using quantitative values. They provide simple summaries about the sample and the measures. This includes calculations of the mean, median, mode, range, standard deviation, variance, and other such parameters. Of course, measures of central tendency are generated and used for this kind of descriptive statistics. In most cases, descriptive statistics provide useful information because we can readily identify tendencies to over- and under-inclusive theories and set parameters of interest. Once you’ve conducted your basic analysis for the variable(s), you’re better positioned to answer research questions.

When you want to collect and analyze information, you will do statistical analysis. This technique can be used to answer important research questions. Generally, any scientific research uses statistical techniques to collect, analyze, visualize, and interpret data. Therefore, in the process of doing academic research, you need to understand the types of statistical analysis in order to make predictions and draw valid conclusions tailored to the research questions. In this article, I will discuss types of statistical analysis in detail, so you are more knowledgeable and understand how to run analysis based on the research questions.

4. Common Applications of Statistics in Academic Research

This definition has three notable features. One is that virtually all research designs involve some kind of “quantitative” i.e., counting and measurement, data, and so can benefit from the use of statistics. Recent technological trends in the social disciplines have accelerated interests in handling and analyzing so-called qualitative data through statistical means. Another feature of the definition is that the “question,” “answer,” and “conclusion” stages are crucial, as decisions about which formulas to use and how to interpret data depend on one’s goals and mindset as much as on the data themselves. With careful planning and sound execution, statistical analysis gives researchers confidence that they are making inferences based on their data. Finally, statistical analysis is both a science and an art: a growing body of scientific knowledge influences what researchers can and cannot do with their data. But in practice, conducting a statistical analysis also leads to new scientific knowledge. In short, the study of statistics is, largely, the study of the complete process of making informed decisions.

The applications of statistical methods are broad and overlap considerably with research design. Each of the research designs and the statistics that relate to them can be employed in a wide range of settings. Researchers use statistics because, had they been able to go out and gather data in a systematic way on a natural phenomenon, they might have been content to describe how often each phenomenon occurred. Instead, researchers must work with available data and accept responsibility for interpreting them in a responsible manner. The onus is on researchers to convince their readers (and themselves) that their descriptions are as accurate as possible within the constraints of their design and their data. Technically, the word “statistics” refers to a set of mathematical functions that one can apply to quantitative information. These functions can be organized into a set of methodologies appropriate for various types of data, for various types of questions.

5. Tips and Resources for Successfully Using Statistics in Assignments

One way to familiarize students with inferences is to show different statistical procedures from existing research studies in their area, rather than teaching them software or formulas. For example, researchers in biology use an independent t-test to compare the means of two different groups, such as women and men. If students see how others utilize the procedures under study, they can understand the concepts better and apply them to their research. Misunderstandings and mistakes while performing the statistical procedures will occur. The author recommends some statistical software to aid in the statistical analysis due to these problems. However, the selection of statistical software depends on the cost, the statistical procedures necessary, the level of computer knowledge, and the ease with which different statistical procedures can be used. Moreover, there are free and easy-to-use software programs such as PSPP, Jamovi, and JASP. Teachers can focus on teaching the basic concepts of statistics to solve simple questions in class activities as an alternative if students do not have good computer skills.

Students writing papers must communicate not only their ideas but also their findings. In addition, researchers can use statistics as a result to conduct further investigations or to have extra information about the population studied. The importance of understanding statistical terms is well established, and thus it is important for all students to have a good grasp of these procedures in order to support their research. After selecting the study subjects, it is important that they have a good understanding of which statistical procedure is the most appropriate for addressing the questions that arise in their particular study, as well as of the concepts of statistics that are relevant to the area of study. To help students understand and recognize the correct statistical procedure to use in their study, teachers should provide them with the necessary knowledge to appeal to this area of statistics, which is of great importance to the study.
