Welcome to class!
In today’s class, we will be talking about data and information. Enjoy the class!
Data and Information
Data is raw, unorganized or unprocessed facts that need to be processed. It can be something simple and seemingly random and useless until it is organized.
Types of data
It is descriptive information (it describes something). Qualitative data is non-statistical and is typically unstructured or semi-structured. This data isn’t necessarily measured using hard numbers used to develop graphs and charts. Instead, it is categorized based on properties, attributes, labels, and other identifiers.
Qualitative data can be used to ask the question “why.” It is investigative and is often open-ended until further research is conducted. Generating this data from qualitative research is used for theorizations, interpretations, developing hypotheses, and initial understandings.
Qualitative data can be generated through:
- Texts and documents
- Audio and video recordings
- Images and symbols
- Interview transcripts and focus groups
- Observations and notes
It is numerical information. Quantitative data is statistical and is typically structured in nature – meaning it is more rigid and defined. This type of data is measured using numbers and values, which makes it a more suitable candidate for data analysis.
Whereas qualitative is open for exploration, quantitative data is much more concise and close-ended. It can be used to ask the questions “how much” or “how many,” followed by conclusive information.
Quantitative data can be generated through:
- Market reports
Classification of quantitative data
- Continuous data
- Discrete data
Examples of data
- Name of thing, place or animal
- Measurements Descriptions of things
Sources of data
- Government documents
- Newspapers and Magazines
- Define data.
- Mention the two types of data
Information can be defined as a processed data that is meaningful to the user. It can be used in the decision-making process.
Examples of information
- Student ID card
- Weather report
- Student’s Report card
- National passport
Sources of information
- Census Board
Ways of handling data
- Electronic Methods
- Non – Electronic Methods
- Define information
- Differentiate in tabular form, between data and information
- Give four examples of data.
- State any five sources of information.
