Astronomy does not employ statistical principles because it primarily focuses on the observation and study of celestial objects and phenomena in the universe, such as stars, planets, galaxies, and cosmic radiation. While data analysis is an important aspect of astronomy, it relies more on mathematical and physical principles rather than statistical methods. In contrast, computational biology, data mining, and actuarial science heavily rely on statistical principles to analyze and interpret data in their respective fields.

Isaac Newton is associated with probability theory because he made significant contributions to the development of the field. In his book "Mathematical Principles of Natural Philosophy," Newton introduced the concept of probability and discussed its application in various areas, including physics and finance. He developed the binomial theorem, which is a fundamental result in probability theory. Additionally, Newton's work on calculus laid the foundation for the mathematical techniques used in probability calculations. Overall, his contributions to probability theory solidify his association with the field.

The most common observation in a data set is called the mode. The mode represents the value or values that occur most frequently in the data set. Unlike the mean or median, which are measures of central tendency, the mode focuses on the frequency of values. It is useful for identifying the most common or popular data point in a set.

The unitary assumption is not an assumption in algebra. The associative assumption states that the grouping of numbers does not affect the result, the unital assumption states that there exists an identity element, and the commutative assumption states that the order of numbers does not affect the result. However, the unitary assumption is not a commonly recognized assumption in algebra.

In a mathematical problem, the order of operations is determined by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). According to this order, division comes before multiplication. Therefore, division should be performed before any multiplication in a mathematical problem.

The study of statistics started in 1663.

Tangents are not a modern presentation of geometry because they have been studied and used in geometry for centuries. Tangents are lines that touch a curve at a single point, and they play a fundamental role in the study of curves and their properties. In contrast, planes, rotations, and lines are all modern presentations of geometry that have been developed and studied in more recent times.

The method of least squares was first described in 1805.

Boolean algebra is the branch of algebra that uses truth values. It is a mathematical structure that deals with binary variables and logical operations. In Boolean algebra, variables can only have two possible values, true or false, and operations such as AND, OR, and NOT are used to manipulate these values. Boolean algebra is widely used in computer science and digital electronics for designing and analyzing logic circuits and algorithms.
