Mathematics and Statistics Overview

Study Notes

Mathematics

Mathematics is a formal system of logic and abstract thought, used to describe patterns, quantities and relationships.
It's a fundamental science that underpins many other fields.
Core branches include algebra, geometry, calculus and analysis.
Algebra deals with symbols and their manipulations, equations, and inequalities.
Geometry studies shapes, sizes, and spatial relationships.
Calculus investigates change and motion, using limits, derivatives and integrals.
Analysis examines the properties of real-valued functions.
Discrete mathematics studies countable, distinct objects.

Statistics

Statistics is a branch of mathematics that deals with collecting, analyzing, interpreting and presenting data.
It's used to understand patterns, trends and relationships in data.
Key concepts in statistics include:
- Descriptive statistics: Summarizing data using measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation, range).
- Inferential statistics: Making inferences about a population from a sample. Used to test hypotheses about populations, and estimate parameters.
- Probability: Quantifying uncertainty and likelihoods of events. Used extensively in inferential statistics.
- Data visualization: Presenting data graphically to reveal insights. Charts and graphs are used.
Statistical methods are used in many fields, including science, social sciences, business, and engineering, to draw conclusions from data.
Common statistical distributions include the normal distribution, t-distribution, and chi-square distribution.
Statistical tests, such as t-tests, ANOVA, and chi-square tests, are employed to analyze data. These tests allow you to make conclusions based on collected data.
Statistical significance tests provide a measure of the certainty of an observed outcome. These methods highlight whether an observed effect is likely to be real, or if it's due to random chance.
Regression analysis examines the relationship between variables. Different types of regression exist to model various relationships.
Time series analysis is a technique used to examine data collected over time to forecast future values or identify patterns.
Hypothesis testing allows researchers to make decisions about an observed outcome. This entails formulating a hypothesis, gathering data, and determining if the data supports or refutes the hypothesis.
