Key Components of Data Science

Data science involves multiple key components that work together to extract insights and value from data. These components include:

1. Data Collection

The first step in data science is data collection. Data can come from various sources, such as social media, customer databases, or sensors, and can be collected in various formats, including structured and unstructured data. It is essential to ensure that the data collected is relevant to the problem at hand and of high quality.

2. Data Preparation

Data preparation involves cleaning, organising, and transforming the collected data into a format that can be analysed. This step involves removing irrelevant data, handling missing values, and transforming the data into a consistent format.

3. Data Analysis

Data analysis involves applying statistical and machine-learning techniques to extract insights from the prepared data. This step involves identifying patterns, correlations, and trends in the data to answer specific questions and solve problems.

4. Data Visualisation

Data visualisation involves presenting the insights derived from the data analysis in a visual format, such as graphs, charts, or maps. Data visualisation makes it easier for decision-makers to understand and communicate the insights and can help identify patterns and trends that may not be apparent in the raw data (Source: DatabaseTown).
