Data Cleaning
Raw data is often messy and requires cleaning before it can be used. Data cleaning involves:
- Handling Missing Values: Filling in, interpolating, or removing missing data.
- Removing Duplicates: Ensuring each data point is unique.
- Correcting Errors: Fixing any inaccuracies or inconsistencies in the data.
- Standardizing Formats: Ensuring consistent formats for dates, numbers, and strings.
How to Create a Dataset?
Creating a dataset is a foundational step in data science, machine learning, and various research fields. A well-constructed dataset can lead to valuable insights, accurate models, and effective decision-making. Here, we will explore the process of creating a dataset, covering everything from data collection to preparation and validation.
Steps to Create a Dataset can be summarised as follows:
