How to apply data science principles in real life? – Jaro Education

Data Science is a multidisciplinary field that combines expertise from statistics, computer science, and domain knowledge to extract meaningful insights from data. It plays a pivotal role in driving data-driven decisions that are crucial for businesses to remain competitive in an increasingly digital world. As per the recent report stated by the Bureau of Labor Statistics, employment in this field is projected to grow by 36% between 2023 and 2033, making it one of the most promising and rapidly expanding career paths.

The principles of Data Science form the bedrock upon which successful programs are built. They guide the strategic direction and execution of projects, ensuring that organizations can effectively use data to achieve their goals. These principles are rooted in five core pillars: Purpose, Plan, Process, People, and Performance. Let’s take a closer look at these key principles, which will help you develop a strong foundation in Data Science:

1. Data Collection

Data collection refers to the operations concerning the conductance of collecting data, which includes various considerations such as what to target in the first place and how valid the data source is in terms of bias and error concerns. Data collection begins with the factor of the amount and quality of data; too little information or too much erroneous information will cause a data science project to fail.

Basic Data Sources: The sources include open data repositories, social media, IoT sensors, databases, APIs, website scraping, and surveys.

Data Challenges: These challenges include anything from unstructured data-like images to issues of putting together a consistent format to ethical considerations that include permission/authorization and consent to use the data in the first place.

Toolbox: Python libraries such as BeautifulSoup and requests, SQL for databases, and data ingestion platforms such as AWS Data Pipeline and Apache Kafka.

2. Use of EDA

Exploratory Data Analysis (EDA) seeks the closeness and/or oddness in data to get the proper picture of the data. Visual representation of patterns and relationships using heatmaps, box plots, scatter plots, and histograms. Finding possible outliers, clusters, or correlations.

3. Data Stewardship

Responsibility is another principle of data science, followed by the accountability of any organization. The primary source to ensure accurate responsibility is driven for the organization’s data to employ steward data.

• Data Quality
• Data Management Policies
• Data Sharing
• Data Accessibility
• Data Transparency
• Data Usage
• Data Governance

4. Data Quality Standards

In a systematic way to make business intelligence effective, each individual needs to check on high-quality and trustworthy data. To improve and modify the quality of your business in the data science process, you should first define and set your quality standards through which the raw material will go, passing the quality assessment, ensuring the product is free from impurities.

The main focus is on quality measurement and recording throughout the data science project process.

5. Transparency

Transparency is the core of any organization, especially in the technology department. It should include the regular recording, relevant data, and feasibility of the data science projects. Every individual within the organization should follow this as the main principle of data science to avoid any corrupted data. A regular audit should be conducted to make sure things run within the framework.

• Build trust between the individuals and organizations.
• Compliance with international laws like GDPR (General Data Protection Regulation)
• Informed decision-making
• Identifying biases and mitigating problems

6. Regression

Regression models in data science are used to label continuous projects, such as predicting the price of raw materials. To achieve regression in the data science process, you can use:

• Linear regression: This technique is used where a relationship is created between an independent variable and the unknown dependent variable.
• Logistic regression: Used in classifying problems where the dependent variable has two possible outcomes.
• Ridge regression: Applied when multicollinearity is present, meaning the independent variables are highly correlated.

7. K-Fold Cross-Validation

K-Fold cross-validation is used when you have small data and limited data validation. This involves partitioning the data into small fragments called K-Folds, allowing for cross-validation sets and test sets, improving data validation by partitioning the sample.

8. Imputation

Imputation is used to estimate missing values in data science projects. Methods of imputation include:

• Categorical value choosing
• Numerical value choosing

9. Confidentiality

Privacy is a fundamental human right, and maintaining confidentiality within data science projects is crucial. Organizations must ensure that data and tasks remain confidential and cannot be shared outside the company.

10. Data Security

Data security is vital in data science. Security measures include:

• Access control (us

Having a solid academic base in the field of Data Science will give the foundation needed for prosperity in that domain. You must start by achieving a bachelor’s degree in computer science or an affiliated area for foundational strength. However, advanced proficiency with strong competition at career grounds would require acquiring a master’s degree from the most esteemed institutions in the world. Master’s level prepares one to obtain advanced and technical expertise which enables individuals to face challenges at that high-end platform.
