Data preparation is an important part of making sure that computers can understand data and use it in helpful and meaningful ways. It is like getting ready to use a recipe for a cake. You need to measure out the right ingredients and put them into the right bowl so you can mix them all together and bake the cake!
Data preparation is similar but instead of ingredients, we are getting ready to use data. We go through the data and organize it so it can be used by computers like a cake recipe. For example, we may look to see if all the names are spelled correctly and that data is stored correctly in the computer. We may also look to see if there is data that should not be used and make sure it's not in the computer. We also make sure to put the data in the right formats, like numbers or words.
After data preparation is complete, the data should be ready for the computer to use. Computers with the right data can help us make predictions, analyze patterns, and solve problems that are too difficult for us to do ourselves!
