Measure of Central Tendency
Measure of Central Tendency
A number that represents the 'middle' of a dataset. Common types include the mean (average), median (middle value), and mode (most frequent value).
Measure of Variability
Measure of Variability
The 'spread' or variability of data in a dataset. Common types include the range (highest - lowest), variance (average squared deviation), and standard deviation (square root of variance).
Descriptive Statistics
Descriptive Statistics
Summarizing and describing main features of a dataset. It helps to visualize and understand the data patterns, but it doesn't make any inference about the population.

Study Notes
Fundamental Concepts
- Mathematics is a system of logic that uses symbols to represent numbers, quantities, and relationships.
- It encompasses various branches, including algebra, geometry, calculus, and statistics.
- Mathematics is used to model and solve problems in various fields, such as science, engineering, and finance.
- Fundamental mathematical operations include addition, subtraction, multiplication, and division.
Number Systems
- Natural numbers (counting numbers) are positive integers starting from 1.
- Whole numbers include all natural numbers and zero.
- Integers consist of positive and negative whole numbers, and zero.
- Rational numbers can be expressed as a fraction of two integers, where the denominator is not zero.
- Irrational numbers cannot be expressed as a fraction of two integers.
- Real numbers encompass all rational and irrational numbers.
- Complex numbers include real and imaginary numbers.
Algebra
- Algebra uses symbols to represent variables and perform operations to solve equations.
- Basic algebraic principles include the commutative, associative, and distributive properties.
- Linear equations involve variables raised to the first power.
- Quadratic equations involve variables raised to the second power.
- Polynomials are algebraic expressions with multiple terms.
- Factoring is the process of finding the factors of an expression.
- Solving equations involves isolating the variable on one side of the equation.
Geometry
- Geometry deals with shapes, sizes, and positions of objects.
- Basic geometric figures include points, lines, angles, triangles, quadrilaterals, and circles.
- Euclidean geometry is a system of geometry based on axioms and postulates.
- Coordinate geometry uses coordinate systems to represent geometric figures.
- Solid geometry deals with three-dimensional shapes and their properties.
- Trigonometry relates angles and sides of triangles.
Calculus
- Calculus involves the study of change and motion.
- Differential calculus deals with rates of change, such as slopes of curves.
- Integral calculus deals with accumulation of quantities, such as areas and volumes.
- Derivatives express the rate of change of a function.
- Integrals calculate the accumulation or summation of a function.
Statistics
- Statistics involves collecting, analyzing, and interpreting data.
- Key statistical concepts include measures of central tendency (mean, median, mode) and measures of variability (range, variance, standard deviation).
- Descriptive statistics summarizes and describes data.
- Inferential statistics draws conclusions about a population based on a sample.
- Probability studies the likelihood of events occurring.
- Data analysis is crucial for understanding trends and patterns in information sets.
Sets
- A set is a well-defined collection of distinct objects or elements.
- Set operations include union, intersection, and difference.
- Venn diagrams are used to visualize relationships between sets.
Logic
- Mathematical logic uses symbolic language to express arguments and prove statements.
- Fundamental logical connectives include and, or, not, or implication (if-then).
- Proofs are used to demonstrate the validity of mathematical statements.
Applications of Math
- Mathematics is essential for science, engineering, and technology, enabling prediction and modeling of events and trends.
- It forms the basis for computer science and programming, facilitating algorithmic design and problem-solving.
- Mathematics is crucial for business and finance, enabling estimations, forecasting, and risk management.
- Its practical applications are widespread, from everyday calculations to complex scientific models.
