By doing that not only you will be clearer with your concepts but will also get more confident. The best experience and deeper knowledge will be all you will get back.
What are the prerequisites to learning data science?
The various online programs or tutorials, and practical courses teach data science from the scratch. Right from the basics of computer fundamentals likes mathematics, algorithm, and statistics to programming languages with python/R, SQL, etc.
A clear knowledge of maths and the concept of integration will be helpful.
The statistics with probability department will become fundamental when you get a detailed course.
Knowledge of at least one programming language, data structures, and OOP programming will be a good help.
Roles & Responsibilities
Some of the key roles of a data scientist are:
- Work with stakeholders to understand the business issues.
- Rectify the problem, prepare the structure and collect the data accordingly.
- Verify the accuracy of data, clean the data accordingly and extract it into meaningful information.
- Find various data patterns and create visualizations to perform data analysis.
- Build algorithms and data models and figure out the accuracy of models.
- Evaluate the end result and acquire solutions as per the feedback.
What Are The Steps Of Learning Data Science?
Make your basics strong in Math and Statistics
Math and statistics are the base and the strength of data science. They are the foundation of the data science field. If you are into data science make sure your calculations and probability are up to the mark. Get the basics right, learn from the beginning at fingertips you will get detail on each data science program.
Here is a video that will guide you to learn the basics of data science.
Learn Python and R programming
Python and R are the most favored programming languages in data science. Along with math concept fundamentals, it’s also necessary to have a good understanding of the programming language. Python and R are open-source programs and anyone interested to learn the program can go for them. The syntax of both is easy to use. They are compatible with Linux, Windows and macOS platforms.
Almost any task can be conveniently pulled up by python and R. When you have to handle extensive data python is the right tool. All the deep learning tasks like web scraping and workflow automation are performed better by Python than compared to R.
When it comes to statistic handling R is the language you can rely on. It has a great collection of statistical languages which you can apply to data sets instantly. R is the best tool for building statistical models compared to python.
If you are aspiring for deep learning or artificial intelligence Python is the best tool for beginners. You can start with R if you are more interested in statistics and model building.
Introduction To The Databases
A data scientist needs to understand and be able to work with databases. Databases are used for data retrieval and data storage.
SQL (Structured Query Language) is the most preferable database language. It allows you to store data, modify the data, and create tables and graphs. It’s an advantage that some big data tools have extensions that allow you to make queries using SQL.
As a data scientist, it’s okay not to have detailed database knowledge. As those particular tasks are performed by database engineers. But it’s good to be familiar with the basics of SQL like data storage and retrieval.
Learn Data Analytical Program
As a data scientist, you must be open to various problem-solving techniques when it comes to data analysis. It is the very important job of the data scientist to have foresight as to which data solutions can be provided to any particular issue.
Cluster analysis, regression system analysis, and cohort analysis are a few techniques that data scientists usually used.
The best data analyst is one who is quick in detecting which data analysis technique is required to relate to any particular problem. This application of the right technique to the problem comes with experience and practice.
Plan, Practice & Perform
After having a good understanding of data analytics, just begin to try your hand at projects that apply all the methods you have learned. It is very important to know the strong fundamentals of programs than to have overall information about everything. Dig down deeper and understand the methods to apply to data analytics.
Make sure that practically you implement python programs or R programming in any statistical issue. Practice well, as only a better understanding of the data solution will give you a wider experience and better prospects.
How to Use Data Science Tools?
Many tools in data science perform different functions. The most popular tools are BigML, D3, MATLAB, Excel, ggplot2, Tableau, etc
It is essential to have good knowledge of and functions of each data science tool. It makes your concept clear as to which particular tool should be used for certain data analytical problems or processes.
At this stage specialization isn’t very necessary, just knowing every tool for study and practice is a good start. The main purpose should be to have a clear idea as to which situation and what tool must be used.
Data Science Projects
Everything that you have learned just binds it up into a project. There are different types of projects. Check out how you can go about it.
Sentiment Based Analysis
This type of project requires sentiments to be attached to any particular text. You can choose the either binary or granular approach and react to the text in various sentimental ways. Like happy, sad, excited, etc.
This type of sentiment-based analysis is usually applied on social media. The feeds are a great source of data and can be used in various ways for the company's benefit. With the right implementation of a hashtag on the project, you can analyze it accordingly.
For example, you have to promote any movie or series on the internet, so there are particular data sets you need to use and make sure that the recommendation program is done properly. All the data that includes actors, subject, runtime, etc is used for the recommendation program.
Communication And Good Presentation Skills
Data scientists need to convey the analysis report clearly so it becomes easy for the client to understand the organics of insights. A good analysis report if not presented in order can create a wrong impression about the report's perspective.
Data that is analyzed should be presented well in an organized way for easy understanding. Communication plays a very important role to line up between the client and their expectation.
The good use of graphics, graphs, reports, charts, and videos should make magic. It will be an easy route toward understanding the audience.
