Study Notes
What is Mathematics
- Mathematics is the study of relationships and patterns through symbols, numbers, letters, and diagrams.
Mathematics in Nature
- Mathematics is used to predict natural phenomena such as the sun's movement and weather forecasts.
- Algebra helps predict population growth, which can inform policy decisions.
- The Fibonacci Sequence appears in nature such as in the growth of rabbit populations and in plant patterns.
- The Golden Ratio, derived from the Fibonacci Sequence, is found in architecture, art, and nature as a measure of beauty and harmony.
Mathematics as a Language
- Mathematics is a language with its own vocabulary, grammar, and syntax.
- It allows for precise and concise expression of complex ideas.
- Mathematical language features include symbols, definitions, quantifiers, variables, and operations.
Problem Solving
- A problem is a situation requiring a solution, found in both theoretical and practical contexts.
- Polya's four-step plan for problem-solving includes understanding the problem, devising a plan, carrying out the plan, and looking back to verify the solution.
- Problem-solving strategies include logical reasoning, pattern recognition, working backwards, considering extreme cases, solving simpler problems, organizing data, making visual representations, accounting for all possibilities, intelligent guessing, and testing.
- Inductive reasoning draws general conclusions from specific examples or observations.
- Deductive reasoning uses general rules to reach specific conclusions.
Scientific Method
- Science is a method for acquiring knowledge about the natural world.
- The scientific method uses observation, experimentation, and a systematic approach to discover hidden knowledge.
- The scientific method is governed by established rules set by the scientific community.
- Characteristics of the scientific method include empirical evidence, objectivity, repeatability, fallibility, caution, and acceptance of uncertainty.
Statistics as a Tool
- Statistics is used to collect, organize, analyze, and interpret data to understand relationships between variables and draw conclusions.
- Statistics provides a means to make informed decisions based on data.
- Key concepts in statistics include variables, data types, measures of central tendency, measures of dispersion, and sampling methods.
- It includes both descriptive statistics (summarizing data) and inferential statistics (making predictions based on samples).
- Types of variables include quantitative (numerical) and qualitative (categorical).
- Quantitative variables can be discrete (countable) or continuous (measurable).
- Types of sampling include probability sampling (random selection) and nonprobability sampling (not everyone has an equal chance).
- Descriptive statistics include measures of central tendency (mean, median, mode) and measures of dispersion (range, variance, standard deviation).
- EDA techniques include bar charts, pie charts, line charts, histograms, and box plots.
- Inferential statistics involve hypothesis testing, where a null hypothesis (no effect or difference) is compared to an alternative hypothesis (effect or difference exists).
- Types of errors in hypothesis testing include Type I error (rejecting a true null hypothesis) and Type II error (accepting a false null hypothesis).
- The normal distribution is a bell-shaped curve that describes the distribution of data.
- The empirical rule states that 68% of values fall within 1 standard deviation from the mean, 95% within 2, and 99.7% within 3.
