Study Notes
Financial Statistics Overview
- Collection of methods used to transform data into useful financial information within a business context.
- Statistics encompasses analysis, interpretation, explanation, and presentation of data.
Descriptive Statistics
- Utilizes charts (graphs) and tables for data visualization.
- Employs numerical measures to summarize data.
Inferential Statistics
- Involves estimation techniques, such as estimating a population mean from sample data.
- Utilizes hypothesis testing to validate claims about population parameters, e.g., testing if mean weight equals 75 KG.
Data Collection Techniques
- Various methods include experiments, telephone surveys, written questionnaires, and personal interviews.
- Data collection is critical for capturing meaningful information.
Key Statistical Concepts
- Population: The entire set of subjects under study (e.g., all employees or students).
- Census: Measuring variables across the entire population.
- Sample: A subset of the population used for analysis.
- Sampling: Selecting a sample based on sound statistical principles.
Parameters vs. Statistics
- Parameters: Descriptive numerical measures calculated from the whole population, often represented by Greek letters.
- Statistics: Corresponding measures derived from a sample data set.
Data Types
-
Timing:
- Cross-sectional data: Collected at one point in time (e.g., consumer sentiment surveys).
- Time series data: Collected over intervals (e.g., daily, monthly sales data) to identify trends.
-
Types:
-
Quantitative Data: Numerical measures, encompassing:
- Discrete (e.g., number of children).
- Continuous (e.g., weight, volume).
- Qualitative Data: Categorical measurements (e.g., marital status, political affiliation).
-
Quantitative Data: Numerical measures, encompassing:
Levels of Measurement
- Interval Data: No true zero point (e.g., temperature).
- Ratio Data: Has a true zero and includes measurements like weight, time, pay rate, and interest rate.
Summary
- Statistics divide into two main areas: Descriptive and Inferential.
- Distinctions made between population and sample, as well as parameters and statistics.
- Types of data categorized by timing (time series vs. cross-sectional), type (qualitative vs. quantitative), and measurement levels (nominal, ordinal, interval, ratio).
