Study Notes
- Statistical data includes arriving at the solution, presentation, analysis, and interpretation.
Types of Statistical Data
- Primary or unpublished data is information collected directly by a researcher or organization for a specific research purpose, and is raw and unprocessed
- Secondary or published data has already been collected by another organization and is available in published form
Arriving at the Solution
- Once data is collected, managers can use it as input and attempt to solve the model.
- The solution provides an answer to the problem under consideration, but only under the condition represented by the model.
Presentation
- Presentation is the strategic arrangement and display of statistical information
- It involves transforming raw data into a format that can be easily grasped and analyzed
Types of Presentation
- Textual presentation involves presenting data using words, sentences, and paragraphs
- Tabular presentation involves organizing data into rows and columns within a table
- Graphical presentation encompasses a wide variety of visual representations designed to effectively communicate statistical data
Analysis
- Data analysis involves using statistical methods to find patterns and trends in data
- Software like spreadsheets helps automate the process, making it faster and reducing errors
Types of Statistical Analysis
- Descriptive Analysis summarizes and organizes data using charts, graphs, and tables to enhance understanding
- Inferential Analysis draws conclusions and makes predictions based on analyzed data
- Predictive Analysis uses past data trends, often with AI and machine learning, to predict future outcomes
- Prescriptive Analysis suggests the best course of action based on data analysis
- Exploratory Data Analysis examines unknown patterns and relationships within data
- Causal Analysis identifies cause-and-effect relationships between variables to understand why something happens
Interpretation
- Statistical data interpretation is the process of analyzing data to draw conclusions using statistical methods
- It involves organizing data into tables, charts, or graphs to make sense of it and derive conclusions
Steps in Interpreting Data
- Gather the data
- Develop Findings
- Draw Conclusion
- Give recommendations
