Study Notes
Overview of Statistics
- Statistics is a science focused on collecting, summarizing, presenting, and analyzing data.
- Analyzing data can lead to conclusions and informed decisions.
Medical Statistics
- Medical statistics applies statistical methods specifically in the medical field.
- The primary unit of interest in medical statistics is typically a living person.
Types of Statistics
- Statistics can be categorized into two main types:
- Descriptive Statistics:
- Organizes and summarizes large datasets.
- Methods include tabular, diagrammatic, or numerical presentations.
- Provides a clear summary of raw data for improved comprehension.
- Analytical Statistics (Inferential Statistics):
- Enables conclusions to be drawn from data analysis.
- Descriptive Statistics:
Populations and Samples
- A population represents a large mass or group of data and can be finite or infinite.
- A sample is a subset of the population that provides insights about the whole group.
- Sampling variation occurs because different samples can yield different results.
Data Analysis and Presentation
- Raw data consists of unorganized data and is often challenging to interpret.
- Illustrating raw data with diagrams enhances understanding; diagrams must be clearly labeled and self-explanatory.
- Frequencies refer to the counts of observations in each category, while relative frequencies express these counts as percentages of the total.
Frequency Distribution
- Constructs a frequency distribution table when raw data is discrete or continuous.
- General rules for forming a frequency distribution include:
- Determine the range of values: ( R = X_{\text{MAX}} - X_{\text{MIN}} + 1 ).
- Identify a convenient number of classes, typically between 5.
