Study Notes
Types of Data
- Blood type examples categorical data, indicating a qualitative difference in types of blood.
- Interest rate is an example of quantitative data, measured numerically.
Data Collection Methods
- Face-to-face interaction is involved in the method of data collection known as interviews or direct observation.
Qualitative Data
- Qualitative data measures attributes, characteristics, or qualities that are descriptive rather than numeric.
- Another term for qualitative data in statistics is categorical data.
Variables
- Continuous variables can assume infinitely many values within an interval, like temperature or height.
- Discrete variables can only take a finite or countable number of values, like the number of students in a class.
Categorical Data
- Categorical data allows classification based on similarities or differences, enabling analyses based on group characteristics.
Statistical Analysis Framework
- The first step in the framework involves defining the objectives and scope of the analysis.
- Primary data refers to data gathered directly from the original source.
- The process of acquiring measurements, counts, or raw data is called data collection.
- Inferential statistics focuses on estimation and hypothesis testing based on data samples.
Recommendations and Reporting
- Recommendations aim to provide actionable insights based on analysis results in the statistical analysis planning framework.
- Summarizing, organizing, and presenting data using graphs and frequency distribution tables occurs in the data analysis step.
- The final step in the framework involves interpreting results and forming conclusions from the analyzed data.
Direct Experience
- Primary data involves gathering information based on direct or first-hand experience, enhancing data reliability.
- Data treatment with statistical tools converts raw data into meaningful information for analysis.
- Determining the sample size is essential before gathering data to ensure the results are statistically valid.
