About Data Handling

Data handling refers to utilizing collected data to find meaningful results to be used in further work.

What is data, and how do you organize it?

Data is what you collect from users in numbers, words, symbols, etc., but the data you collect is in raw form or unorganized and needs to be organized to draw meaningful results.

While trying to use data to make sense of it, we use the following terms and processes:

• Pictograph - Using pictures to group data.
• Bar Graph - Using single graphs to visualize data.
• Double Bar Graph - You use this method to compare two types of data.
• Pie charts - Graphing the data in a pie chart to represent it efficiently.
• Grouped Frequency Distribution - You make a table of huge data to represent it efficiently.
• Histograms - Histograms are bar graphs made using grouped Frequency Distribution.
• Tally Marks - Another way to represent data using GFD

You also use methods like probability (chance of occurrence of an event) to use the data to predict events and their chances to happen in the real world. probability consists of methods and terms like:

• Equally Likely Outcomes
• Random Experiment
• Experiment and Outcomes
• Experimental Probability
• Probability of an Event

These are all used to raw group data and efficiently to infer proper conclusions.
