1. Introduction to Statistics Projects

One should get a relatively good understanding of fundamental statistical concepts, like descriptive measures, correlation, probability and distributions, statistical inference, and simple data analysis before applying these techniques. The reader is encouraged to read and understand those first. After performing the individual and group statistical questions and problems in each of the techniques studied in this guide, the students are expected to gain the necessary command to achieve a statistical data analysis project. These are already common problems contained in the literature, real-life statistics problems to motivate, and other computer problems given by the instructor.

In this guide, we aim to give an overview of several statistical techniques to be applied in a project study. These techniques are discussed in detail so that they can be applied hands-on using statistical software. In contrast to most existing guides, which can be strained with details, this guide provides necessary details in every step to take. With many years of teaching and applying statistical techniques, we have accumulated a lot of knowledge which we now wish to share. The guide intends to cover most of the comprehensive applied statistical guide and will be very useful for students in statistics, students in the business school, and professionals in general.

2. Common Types of Statistics Projects

2.1. Data Description Projects can be developed to help students learn the principles of simple quantitative data analysis as a means of assisting with managerial decision making. By examining distributions’ shapes, central tendencies, dispersion patterns, probability calculations, and the resulting data characteristics, students can gain practical research experience. They will also become more familiar with data-driven decision-making when confronted with business problems. Students are actively involved in reviewing data characteristics using quantitative analysis techniques. For example, central tendency and dispersion measurements, probability distributions, time series analysis, etc. are evaluated using modeling software. How findings are utilized for forecasting… what these numbers really entail are key components of understanding projects of this nature.

Common types of projects in the field of statistics include those designed to focus on data description, data inference, statistical experimental design and observational study design, and those more closely aligned with mathematics or computer programming. This section will review the various different types of capstone projects, identifying the purpose of each project and listing examples of specific projects by example.

3. Key Steps in Conducting a Statistics Project

To the trained statistician, probability provides a framework that relates the population to the sample. It tells the statistician about the chance that the sample is different from the population. Probability measures the uncertainty or the randomness associated with the inference made by the statistician. Probability also concerns notions of uncertainty measured by game theory; insurance companies based the computation of premiums on the application of probability. Finally, the combination of probability and statistics lies at the heart of modern scientific and industrial discovery.

At the heart of any statistics project is the search for answers to a specific question about a population, whether located in one town, in a city, in a country, or even somewhere scattered around the world. A statistician answers questions about populations by carrying out statistical inference, which uses sample data to make an inference about population parameters. For example, suppose you want to determine the average mileage of cars driven. By measuring the mileage of a sample of cars, you can make inferences about the average mileage of all cars. Statistical inference is a process that is based on probability.

4. Case Studies and Examples of Successful Statistics Projects

Clearly, these case study reports do not cover all the statistical activities nor fully the range of scientific disciplines. But still, there are many common features and elements among these reports. And these common features and elements are often obscure or overlooked in the analysis process. Accordingly, we hope that the examples we have chosen – and the many other models of statistical analysis – will help you discover how to apply the material in this book. We want to give you the confidence to press ahead to learn from data and then to communicate your insights and findings. We are interested in providing a manual to help with this adventure. Though considering the wide range of statistical activities, this manual must be read actively for information sniffed out by your nose as well as digested and mulled over.

The following are complete adventures of data analysis. The goal is to demonstrate the spectrum of activities and techniques that are encompassed by the broad term “statistical analysis.” Collectively, these reports give a representative overview of activities ranging from exploratory and inferential statistics; mathematical, graphical, and visual techniques; computing and simulation; and simple and complex study designs. It is also hoped that with the help of these case studies, readers recognize the power of statistical analysis to communicate insights and findings from data.

5. Conclusion and Future Directions in Statistics Projects

In the future, research can be worked on how statistical practices are used in business domain projects using original or artificial data obtained from business enterprises and forecasting on financial markets can also be made using alternative time series projects. Also, arrangements can be made concerning how to overcome some difficulties arising in applications by using various techniques and which approach to be followed in project practices can be further studied. Moreover, it is also thought that how different types of software are easier to use for industrialists based on sectoral matrices. To demonstrate statistical applications taken place in various business domains, it is intended to organize statistical workshops in order to support statistical studies ongoing in public and industrial applications.

It is now possible to efficiently perform many projects with R and Python. Due to multiple studies conducted in the programming domain in recent years, it’s apparent that studying R and Python programming languages is currently very beneficial in the statistics domain. As the number of libraries on GitHub written in R and Python programming languages are increasing, different types of software are easy to access in data science and statisticians are also encouraged to use R and Python programming languages instead of classical software in their work. We think that thanks to this study, statisticians will also benefit by observing how computational practices have been performed by transforming them into applications on real projects. Finally, it’s ongoing to work on industrial projects with statisticians and software developers. Mostly, public data accumulated in local and state governments have been analyzed.

In this study, we implemented various statistical techniques on real-world projects in order to show the wide range of statistical parameters and existence of the mentioned techniques in different types of projects. We shared some of the most important results in sampling, building models, some ways concerning feature engineering, visualization tools, explanations provided by SHAP library and natural language processing techniques with statistical contributions. Additionally, we made a practical comparison between the most popular feature scaling procedures used in data preprocessing which concern a source of error especially for beginners in statistics.
