Probability theory deals with phenomena whose outcome is affected by random events, and therefore they cannot be predicted with certainty. For example, the result of throwing a coin or a dice, the time of occurrence of a natural phenomenon or disaster (e.g. snowfall, earthquake, tsunami etc.) are some of the cases where “randomness” plays an […]
In today’s data-driven world, we hear about making decisions based on the data all the time. Hypothesis testing plays a crucial role in that process, whether you’re in academia, making business decisions, or in quality improvement. Without hypothesis tests, you risk drawing the wrong conclusions and making bad decisions. That can be costly, either in […]

This introductory textbook provides an inexpensive, brief overview of statistics to help readers gain a better understanding of how statistics work and how to interpret them correctly. Each chapter describes a different statistical technique, ranging from basic concepts like central tendency and describing distributions to more advanced concepts such as t tests, regression, repeated-measures ANOVA, […]
Let’s listen to the data.” “Do you have the numbers to back that up?” We live in an age and society where we trust technology and quantifiable information more than we trust each other—and sometimes ourselves. The gut feeling and conviction of Steve Jobs to know “what consumers would later want” is revered and romanticized. […]
The evolution of technology and knowledge influences the way we teach clinical skills to nursing students and improves the quality of care possible for every patient. However, the foundation for success in performing nursing skills remains a competent, wellinformed nurse who thinks critically and asks the right questions at the right time. That outcome is […]
