## What skills do data scientists need?

A lot of skills and knowledge required to become a data scientist. Skills that include:

1. Mathematics and Statistics- Mathematical and statistical operations play an important role in Data Science. It consists of most of the probability, linear algebra and basic calculus concepts. Most of the algorithm are basic building blocks of statistics. Linear algebra gives the output in the matrix form. Calculation of the gradients are very important in neural networks, so it is an indivisible part of the data science. Especially calculus is part of deep learning in data science.

2. Algorithms- With the algorithmic knowledge, data scientists can easily write efficient pseudo codes which saves much more time. Data scientists are nothing but programmers so they must have the basic and advanced knowledge of algorithms. Algorithms are specially used for the training of models with datasets.

3. Programming Language- Python and R are widely used languages in data science. So data scientist needs mastery in one of these languages. As these are open source languages, they have huge community support. A data scientist cannot apply the algorithms without programming knowledge.

4. Libraries and Framework- Machine Learning is a part of data science and it involves many libraries and frameworks. Following are libraries and frameworks used in data science:

• Numpy- Numpy is a python library basically used for data manipulation and linear algebra. It is used for complex mathematical equations.
• Pandas- Pandas library used for combining, grouping and filtering of data. It supports operations like aggregation, sorting, indexing etc.
• SKlearn- Sklearn is one of the most popular libraries used for working on complex data.
• Matplotlib- It is specially used for the 2D graphs.
• TensorFlow- It is developed by Google and used for writing algorithms for the neural network.
• Pytorch- Pytorch is deep learning framework specially used for computation.
• Django- Django is a popular web development framework written in python.

5. SQL- Database is the most important part of data science for storing the data. Databases like MySql, PostgreSql, MongoDB are specially used. Along with this Oracle database, IBM DB2 etc are the most popular database infrastructures in use.

## What is a Data Science Tool?

Data science tools ease the work like data analysis, extraction and processing of data by going in-depth into complex data. Most of the data science tools are free and have huge community support. We can do faster and effective operations on data by using such tools. These tools literally help to maintain the workflow and perform powerful operations.

Let’s discuss in depth about these tools in the next point.
