Being a data scientist means constantly growing, enabling businesses to become more data-propelled, and learning newer trends and tools. There are various excellent resources in data science that can help you to develop your skillset. According to International Data Corporation (IDC), organizations are turning towards digitalization completely. This will help to create more investments, technology development and open various new jobs.
Currently, numerous resources are being created on the internet consisting of data science websites, data analytics websites, data science portfolio websites, data scientist portfolio websites and so on. So, having the right knowledge of tools and technology is important for handling such data. The easiest way to get started is by taking an online data science bootcamp job guarantee program. Most aspirants either spend too much time in search of the right course or the right technology.
Steps to Learn and Master Data Science
Learning a Language – Python
Choosing and learning a new programming language is not an easy thing, in terms of learning data science, Python comes out first. Python is a high-level, interpreted, general-purpose, object-oriented programming language. Python provides great functionality to deal with mathematics, statistics and scientific function.

Learning Data Analysis in Excel
Data analysis is a process of inspecting, cleaning, transforming and modelling data with an objective of uncover the useful knowledge, results and supporting decision. Best Website for excel: excelexposure.com
Learning Data Visualisation
To discover hidden truth or information on business problem, data needs to be viewed properly. Appropriate data visualisation tool selection is important, to know what to expect from data is also important. Various data visualizations are used in Exploratory data analysis (EDA). EDA is used by data scientists to analyse and explore data sets and summarize their properties, often using data visualization techniques.

Start learning Inferential Statistics and Hypothesis Testing
Exploratory data analysis helps you to know patterns and trends in the data using many methods and approaches. In data analysis, EDA performs an important role. Hence, data analyst utilizes most of their time doing EDA. Sometimes, due to time constraints and resource constraints you can handle large-size data. Time like this asks for sampling methods and approaches. Instead of using whole data in analysis, data analyst tends to find defect or abnormality in the sample. Then, based on this information from the sample, defect or abnormality the rate for whole dataset is considered. This process of inferring the information from sample data is known as ‘inferential statistics.’
Hypothesis testing is a part of inferential statistics which uses data from a sample to analyse results about whole dataset or population. Hypothesis testing is done to know the null hypothesis can be rejected or fail to reject. If the null hypothesis is rejected, then the research hypothesis can be accepted. If the null hypothesis is accepted, then the research hypothesis is rejected.

Start learning database design and SQL
A database is a structured data collection that is stored and accessed electronically. File systems can store small datasets, while computer clusters or cloud storage keeps larger datasets. According to a database model, the organization of data is known as database design. The designer must decide and understand the data storage, and inter-relation of data elements. Considering this information database model is fitted with data.
SQL stands for Structured Query Language. It is created for the recovery and control of data in a relational database.

Start Machine Learning
Machine learning is a part of artificial intelligence that concentrate on the utilization of data knowledge and algorithms to follow methods that human learns and moderately improves its accuracy. Machine learning has four key types as follows:
- Supervised learning: In supervised learning, we introduce the algorithm’s product into the structure so that the system notices the patterns and trends before working on them.
- Semi-Supervised learning: Semi-supervised learning utilises an arrangement of a small quantity of labelled data and a large quantity of unlabelled data to develop models.
- Unsupervised learning: The unsupervised learning technique is impressive for displaying correlation and understanding in unlabelled datasets. Models introduce input data with unspecified useful outcomes.
- Reinforcement learning: The reinforcement learning technique in machine learning controls the best track or choice to select in condition to maximize the profit. Leading machine learning examples in daily life-like video games, utilize this approach.

Learn by Working on Projects
Working on hands-on projects gives you a real understanding and learning of the topic. Hence it is always good to work on the project. Implementation of various tools and methods to gain more knowledge on data, find insights and convert insights into useful decisions. Hands-on projects also teach collaboration, workflow of process and different experiences with the problem statement.
Data science project cycle is composed of six phases:
- Business understanding
- Data understanding
- Data preparation
This is the greater abstraction level of the Crisp-DM methodology, meaning one that can apply, with no exception, to all data problems. Know more about Kaggle for data science.
