Statistics Introduction: Florence Nightingale

Florence Nightingale's View on Statistics

• Considered statistics the most important science, essential for the application of all other sciences and arts.
• Emphasized statistics as crucial for political, social administration, and education.
• Suggested that understanding statistics is akin to understanding divine purpose.

Definition of Statistics

• In plural: Refers to numerical data sets (e.g., beauty contest vital statistics, monthly sales).
• In singular: Defined as a science dealing with data collection, presentation, analysis, and interpretation.

General Uses of Statistics

• Aids in decision-making processes by providing comparisons and justifications.
• Explains past actions and predicts future outcomes.
• Estimates unknown quantities while summarizing data for public utility.

Application of Statistics

• Grown significantly in the 20th century, influencing diverse fields such as education, agriculture, economics, biology, and medicine.
• Increasingly relevant in hard sciences like astronomy, geology, and physics.

Role of Statistics in Various Fields

• Biological and Medical Sciences: Aids in discovering variable relationships and evaluating treatment effectiveness.
• Example: Analyzing the relationship between blood pressure increases and age.
• Social Sciences: Supports empirical research to formulate new socio-political theories.
• Example: Developing a socio-economic profile of the middle class.
• Business: Facilitates sales forecasting, product design, and efficiency in production.
• Example: Using statistical analysis to determine the effectiveness of a new pharmaceutical formula.
• Engineering: Tests material properties for quality control purposes.
• Example: Estimating product lifespan based on current equipment.

Fields of Statistics

• Applied Statistics: Involves techniques for data collection, presentation, analysis, and interpretation.
• Mathematical Statistics: Focuses on developing theories that underpin statistical methods.

Major Areas of Statistics

• Descriptive Statistics:

  • Concerned with summarizing and analyzing data without making wider inferences.
  • Aims to present data clearly.
  • Conclusions apply only to the specific dataset.
  • Example: Graphing census data by age and sex in the Philippines or presenting honor roll statistics at universities.

• Inferential Statistics:

  • Involves making predictions or inferences about a larger population based on a sample.
  • Focuses on predicting and drawing conclusions from the data.
  • Conclusions are generalizable beyond the sample.
  • Example: Testing a new milk formula on a sample of infants to assess developmental impact.
