In summary: You can't read the painting anymore because you have all the information. A bit is represented by a 1 or a 0, and these 1s and 0s are put together to make up sequences of bytes. If you have a file that is 2GB in size, it would be made up of 2 billion 1s and 0s. The CPU in your computer, the processor, uses these bytes to actually process the 1s and 0s, which are then represented as pixels on your monitor. Data is simply bits that can be stored magnetically on an hard drive, or digitally on a DVD.

I think data is an abstraction. It is meaningless, by itself, but definable within a system. data in a computer, is whatever we define it to be.

This is quite true.

Sometimes someone will ask me what particular file is that they don't recognize and can't open with any known program. I suggest they open it in Notepad to see what's in it.

They look surprised "You can do that?"

"Of course (though it might appear to be gobbledegook). All bytes are merely 0-255; it is merely a matter of how they are interpreted. Notepad happens to assign them ASCII letters. Another program might assign them colours. Regardless, they're still just 0-255. The file is interpretation-agnostic. It doesn't know how its data will be interpreted by any given program (although the file can make suggestions, such as "my data is only meaningful as ASCII")

Information = data with meaning.

The two main types of data are quantitative and qualitative. Quantitative data consists of numerical values, while qualitative data includes descriptive or categorical information.

How is data collected?

Data can be collected through various methods such as surveys, experiments, observations, and interviews. It can also be gathered from existing sources such as databases and online platforms.

What is the importance of data in science?

Data is crucial in science as it provides evidence and supports or refutes hypotheses. It also allows for the discovery of patterns and relationships, leading to new insights and advancements in various fields.

How is data analyzed?

Data analysis involves organizing, cleaning, and interpreting data to uncover meaningful patterns and trends. This can be done manually or with the help of statistical tools and software.
