Study Notes
Data Management: Introduction
- Data provides partial insights, not a complete picture.
- Ethical data handling ensures respect for individuals, trust, and moral principles.
- Importance of ethical awareness in handling information.
Principles of Ethical Data Handling
- Keeping information safe and secure.
- Being honest and fair when dealing with data.
- Ensuring clarity and transparency in data presentation.
- Obtaining informed consent when working with data.
Types of Data
- Categorical Data: Groups individuals/objects based on characteristics (e.g., gender, eye color, blood type).
- Numerical Data: Uses exact numerical values (e.g., height, weight, age).
Classifying Numerical Data
- Discrete Variables: Countable values (e.g., number of children, male students, patients with T.B.).
- Continuous Variables: Values obtained by measuring (e.g., temperature, distance, age, height, weight).
Data Presentation
- Textual Presentation: Combines text and numerical facts in narrative form.
- Tabular Presentation: Arranges data in rows and columns, offering clear numeric insights.
- Graphical Presentation: Visualizes data using charts, graphs, and pictures for easy understanding and trend analysis.
Graphical Presentation Benefits
- Provides a quick overview of data.
- Facilitates comparisons between different data points.
- Reveals trends and relationships within the data.
- Shows changes over time and frequency distribution.
- Demonstrates correlation and relative shares.
Interpreting Graphs
- Different types of graphs are used for showing different types of information.
- Choosing the right type of graph is essential for effective communication.
- Histograms are commonly used to represent numerical data, providing insights into the frequency distribution.
