Study Notes
Introduction to Statistics
- Statistics is a field that has evolved over centuries.
- It started as simple data collection that progressed to sophisticated methods.
- Statistics plays a critical role in everyday life.
Early Beginnings (Ancient Civilizations)
- Ancient civilizations like Babylonians, Egyptians, Chinese, and Romans collected data for things like taxation, population censuses, and agriculture planning.
- The word "statistics" comes from the Latin word "status" (state), reflecting its early use in government.
- Examples include the Domesday Book in England.
- Ancient Greek mathematicians, like Euclid and Pythagoras, contributed foundational mathematical concepts used in statistics.
Development in Probability Theory (17th-18th Century)
- Probability theory emerged in the 17th century, spurred by gambling problems.
- Key figures include Blaise Pascal and Pierre de Fermat, who pioneered probability studies through correspondence about dice games.
- Christiaan Huygens published the first book on probability theory, De Ratiociniis in Ludo Aleae (1657).
Emergence of Modern Statistics (19th Century)
- Carl Friedrich Gauss developed the method of least squares and the Gaussian distribution (normal distribution).
- Adolphe Quetelet applied statistical methods to social sciences. He introduced the concept of "average man".
- Statistics became more prominent in astronomy, biology, and public health.
- Florence Nightingale used statistical graphs to improve sanitary conditions during the Crimean War.
- Data visualization techniques, such as pie charts and bar graphs, made statistics more accessible.
Formalization and Expansion (20th Century)
- Ronald A. Fisher revolutionized modern statistics. His contributions include analysis of variance (ANOVA), maximum likelihood estimation, and experimental design.
- Jerzy Neyman and Egon Pearson introduced hypothesis testing frameworks.
- W. Edwards Deming championed statistical quality control, which was vital for post-World War II industrial recovery in Japan.
- Statistical inference became crucial for drawing conclusions from samples about populations
Rise of Computational Statistics (Late 20th Century - Present)
- Computer development enabled large-scale data analysis.
- Statistical software like SAS, SPSS, and R became essential tools.
- Big data and machine learning has intertwined statistics with computer science, focusing on predictive modeling and artificial intelligence.
- Bayesian methods have become more widely used due to computational improvements.
Contemporary Developments
- Statistics is widely used in various disciplines (e.g. medicine, climate science, economics, sports analytics).
- Data ethics is an increasingly important consideration in statistics,
- Advances in technology (real-time data analysis, cloud computing, IoT) shape the field.
Key Milestones in Statistical History
- Periods like ancient times, 17th & 19th centuries, 20th century, and the modern era each had notable figures and events.
Role of Statistics in Everyday Life
- Statistics is essential in decision-making in various aspects of daily life.
- Personal finances, shopping, health and fitness, education, workplaces, business decisions, healthcare, media, and technology all use statistics.
Basic Statistical Terminology
- Population: The complete set of individuals, items, or data sharing a characteristic.
- Sample: A subset of the population selected for study.
- Variables: Characteristics or attributes varying among individuals or items (qualitative - categories; quantitative - numerical).
- Randomness: Outcomes are uncertain, but their distribution is predictable over the long term, crucial for unbiased sampling.
Data Types
- Quantitative Data: Numerical data representing quantities.
- Qualitative Data: Descriptive data describing categories or labels.
Example Scenario
- The example scenario describes how a researcher might study high school students' eating habits by defining the population (all high school students in the city), selecting a sample, identifying variables (qualitative variables like diet type and quantitative variables like meals per day), randomly selecting participants, and collecting data to draw conclusions.
