A consecutive case series is a type of observational study in which a sequence of cases is collected and analyzed to understand particular characteristics, outcomes, and trends within a specific population or condition. In this type of study, patients are included in the series based on the order of their presentation or diagnosis, ensuring that all eligible cases that meet predefined criteria are included in a systematic manner, typically within a defined time frame.
Controlling for a variable refers to the statistical technique used to account for the potential influence of one or more variables that could affect the relationship being studied between the independent variable(s) and the dependent variable. When researchers control for a variable, they aim to isolate the effect of the primary independent variable by removing the confounding effect of the controlled variable(s). This process is commonly used in research to ensure that the results reflect the true relationship between the variables of interest, rather than being distorted by other factors.
Overweight is a term used to describe a person who has a body weight greater than what is considered healthy for their height. It is typically assessed using the Body Mass Index (BMI), which is a calculation based on a person's weight in relation to their height. BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²). According to the World Health Organization (WHO): - A BMI of 25 to 29.
The "Lady tasting tea" is a famous thought experiment introduced by the statistician Ronald A. Fisher in his 1935 book "The Design of Experiments." The scenario serves as an illustration of hypothesis testing and the logic of statistical inference. In the thought experiment, a lady claims she has the ability to distinguish between tea that has been brewed with milk added first and tea that has the milk added after brewing.
Minimisation is a randomisation technique used in clinical trials to ensure that treatment groups are comparable with respect to certain baseline characteristics. It is particularly useful in small trials where random assignment alone may result in imbalances between groups. The primary goal of minimisation is to reduce the potential for bias that could affect the trial's outcomes. In a minimisation process, as each participant is assigned to a treatment group, the allocation is influenced by existing group characteristics.
An N of 1 trial is a type of experimental design used in clinical research, particularly in the fields of medicine and psychology, where a single patient (the "N" refers to the number of participants in the trial) is studied over time to evaluate the effects of a treatment or intervention. In these trials, the individual serves as their own control, allowing researchers to assess the efficacy and safety of a treatment on that specific person.
The One-Factor-at-a-Time (OFAT) method is an experimental design approach used primarily in scientific research and engineering to study the effects of individual variables on a particular outcome or response. In this method, one factor (or variable) is varied systematically while keeping all other factors constant. This is done to observe how changes in that one variable influence the outcome, which helps in identifying relationships between factors and the response variable.
Brainwave entrainment is a process that uses rhythmic stimuli—such as sound, light, or tactile sensations—to synchronize brainwave frequencies to a specific rhythm. This technique is based on the principle that the brain tends to align its electrical activity with external stimuli. Different brainwave patterns are associated with various states of consciousness, such as relaxation, focus, sleep, and meditation.
EEG microstates refer to brief, stable patterns of electrical activity observed in electroencephalography (EEG) recordings. These microstates represent specific configurations of brain activity that can last for a few tens of milliseconds. They are thought to reflect fundamental building blocks of neural processing and are associated with various cognitive states and functions. Research has identified several distinct EEG microstates, typically labeled as A, B, C, and D.
Evoked activity refers to changes in electrical activity in the brain or nervous system that are directly triggered by specific sensory stimuli or events. This is typically measured using techniques like electroencephalography (EEG) or magnetoencephalography (MEG), which can capture the brain’s electrical patterns in response to stimuli.
The postictal state refers to the period of recovery following a seizure. After the active phase of a seizure, individuals may experience various symptoms and effects as their brain and body return to baseline functioning. This phase can last from a few minutes to several hours and sometimes longer, depending on the individual and the type of seizure they experienced.
Weight classes are divisions in competitive sports, particularly in combat sports like boxing, wrestling, MMA (mixed martial arts), and weightlifting, that categorize athletes based on their body weight. The purpose of weight classes is to ensure fair competition by matching opponents of similar size and weight, thereby minimizing the advantages that disproportionately larger or heavier competitors might have. Each sport has its own specific weight class divisions, which can vary in number and weight limits.
The Corpulence Index is a measure used to assess body composition, specifically to evaluate the degree of corpulence or fatness of an individual. It is calculated by using parameters such as the individual's weight and height.
Low birth weight (LBW) refers to a birth weight of less than 2,500 grams (5 pounds, 8 ounces), regardless of the gestational age at which the baby is born. LBW can result from various factors, including preterm birth (being born before 37 weeks of pregnancy) or being born small for gestational age (SGA), meaning the baby is smaller than the typical weight for their gestational age.
Bantam refers to a lightweight military vehicle, specifically the Bantam BRC, which was an early prototype of what would later become the iconic Jeep used during World War II. Developed by the American Bantam Car Company in 1940, the Bantam BRC was designed to meet the U.S. Army's requirements for a versatile and mobile reconnaissance vehicle.
The shortest players in NBA history are well-known for their remarkable skills despite their height. Here’s a list of some of the shortest players in NBA history: 1. **Muggsy Bogues** - Standing at 5 feet 3 inches (1.60 m), he is the shortest player ever in the NBA. He played from 1987 to 2001, primarily with the Charlotte Hornets.
In mathematics, particularly in set theory, "set classes" can refer to categories of sets that share certain properties or characteristics. While there isn't a universally standardized "list of set classes," here are some commonly recognized categories: 1. **Finite Sets**: Sets that contain a finite number of elements. For example, the set \( A = \{1, 2, 3\} \) is a finite set with three elements.
The term "Pygmy" refers to various ethnic groups traditionally found in Central Africa, particularly in the rainforest regions of countries like Cameroon, Gabon, the Republic of Congo, and the Democratic Republic of the Congo. Pygmy peoples are known for their distinct cultural practices, languages, and ways of life, often characterized by a deep connection to the forest.
"Tall Girl" is a coming-of-age romantic comedy film that premiered on Netflix on September 13, 2019. Directed by Nzingha Stewart, the film follows the story of Jodi Kreyman, a high school girl who struggles with her height, standing at 6'1" tall, and the social challenges that come with it. Jodi feels out of place and insecure because of her stature, which sets her apart from her peers.
A Forte number is a term used in the context of combinatorial number theory, specifically in relation to the enumeration of certain types of mathematical objects. The concept is named after the mathematician N. J. A. Sloane and is often associated with advancing the study of integer sequences. In a more general sense, Forte numbers can refer to specific integer sequences or properties derived from particular mathematical operations or functions.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
