Study Notes
Introduction to Statistics
- Statistics is the process of converting data into information.
- Statistics is the science of collecting, organizing, presenting, analyzing, and interpreting numerical data to make effective decisions under uncertainty.
Branches of Statistics
- Descriptive Statistics: Summarizes and presents data to understand its features and characteristics. This can be done through tables and charts. It helps identify relationships among variables and outliers. It is also used to test assumptions about data.
- Inferential Statistics: Makes conclusions about a population based on a sample. Conclusions are made with a degree of certainty.
Descriptive Statistics Details
- Descriptive statistics aims to summarize and present numerical data to gain useful insights.
- Data can be summarized using tables or charts.
- Main features of data distributions can be identified.
- Relationships among variables can be determined.
- Outliers in data can be identified.
- Data assumptions can be tested.
Inferential Statistics Details
- Statistical inference is the process of drawing conclusions about a population based on sample data.
- Statistical inference generalizes from a sample to a population with a calculated degree of certainty.
- It involves learning about population parameters based on sample statistics.
Applications of Statistics
- Business: Quality control, testing products
- Economics: Analyzing relationships between supply and demand.
- Banking: Estimating the number of depositors and claims based on probability.
- Administration: Preparing government budgets
Important Statistical Concepts
- Population: All individuals, objects, or events of interest.
- Sample: A representative portion of a population.
- Parameter: A numerical measure describing a population characteristic.
- Statistic: A numerical measure describing a sample characteristic.
Limitations of Statistics
- Statistics doesn't deal with individual values.
- Statistical conclusions aren't always universally true.
- Statistical interpretation requires high skill and subject understanding.
- Statistics can be misused.
