Today, we're going to discuss what data is. Data refers to any facts, figures, or information that can be recorded and stored. Can anyone give me some examples of data?
My name and age are data.
Photos and videos are also data.
Exactly! Data can include anything observable. Let's remember that it can be a name, a video file, or even temperature readings. So, what are some types of data?
We collect data using different methods: surveys, observations, sensors, and transactions. Student_4, can you tell us a method and an example?
Observation, like watching student behaviors on CCTV.
Perfect! Now after we collect data, where do we store it?
In local storage like USBs or in the cloud.
Exactly! And it’s crucial that we store data securely. Good data must be accurate and timely. Can anyone tell me why?
Because inaccurate data can lead to wrong decisions!
As we understand data, we must also consider ethics. What does data privacy mean?
It means only authorized people should access personal data.
Exactly! And how can we ensure our data is good?
By making sure it’s accurate, complete, and consistent!
Well said! Always keep in mind that data ethics protects against misuse. Let's summarize our discussion.
Facts or figures collected for reference.
Organized data easily searchable in databases.
Data not organized in a fixed format.
Partially organized data.
Points from which data is collected.
Techniques to gather data.
How and where data is kept.
Formats used to present data.
Responsible use and handling of data.
When data's found, it’s all around, from figures tall to images small.
Once upon a time, there was a magic box (data) that could hold names, photos, and everything you can think of! The box was organized (structured) or sometimes messy (unstructured) depending on its contents.
Remember 'SUS' for types of data: Structured, Unstructured, Semi-structured.
D.C. for Data Collection: How we Gather, Observe, and Test.
