Imagine you’re at your favorite café on a busy morning. The air is filled with the delicious smell of coffee being made and the tempting aroma of freshly baked pastries. Behind the counter, there are different baristas, each with their own special way of making coffee. Some pour the milk in a fancy way, while others focus on getting the water temperature and coffee grind just right. Even though they use the same ingredients, each cup of coffee they make tastes different and tells a story about who made it. That’s what makes your coffee experience there special, and it keeps you coming back for more.
Now, let’s think of data in the same way. Data is like that café, but instead of coffee, it’s a busy place where information comes together from many sources like the internet, businesses, scientific research, and even our own devices. Just like each barista creates a unique cup of coffee, every piece of data has its own story and special traits. It might surprise you, but we are all data baristas, too! Every time we click, search, or buy something online, we add to this huge collection of information.
What is data uniqueness, and why is it important?
Imagine you are working with a list of all the basketball players in an Olympic game, but some names appear more than once. If you’re trying to find out the average height, you might end up with a number that’s higher or lower than it should be. This could make the basketball team seem taller or shorter than they really are! The same thing happens in data analysis when we have non-unique or duplicate data.
In some cases, like when using machine learning (think of it as a super-smart computer program that learns from data), if there are duplicates, the model might just memorize the data instead of learning from it. This is like memorizing the answers to a math test instead of learning how to solve the problems. This memorization won’t help when the model encounters new data, just like memorizing answers won’t help when you see new math problems!
- Data uniqueness means all data entries in a dataset are different, and no two are the same.
- If our data isn’t unique, it can lead to biased results.
- Duplicate data can cause overfitting in machine learning models.
- If the data isn’t unique, we might need to clean it to remove duplicates.
How do we explore duplicate data and cardinality in a dataset?
- Identify duplicates and cardinality
What should we do, and what should we be careful about when checking the uniqueness of values in a dataset?
- Always check if data needs to be unique.
- In the case of duplicate records, check if they are true duplicates or if they indicate separate instances that happened to be the same.
- Don’t remove all duplicate records without understanding why they’re there.
- Don’t assume that a low number of unique values (low cardinality) in a column means it isn’t useful.
