Technical skills

Let’s go through some of the technical skills needed to become a data scientist.

  1. Mathematics and statistics

Data Science is extracting knowledge and insights and making informed decisions from data using capital methods, algorithms, or systems. Making conclusions, estimating, or predicting are thus fundamental aspects of Data Science. 

Probability, when combined with statistical approaches, helps in the generation of results for future investigation. Statistics is mostly based on probability theory, in addition to probability distributions, sampling and population, CLT, skewness and kurtosis, inferential statistics such as hypothesis testing and confidence intervals, and so on.

  1. Data manipulation and analysis

It is critical to know how to cope with data flaws. Data manipulation is changing and mapping raw data from one form to another to prepare the data for further study. You simply obtain data and important aggregate variables and then purify the data for data manipulation.

Understanding analytical tools are important for a data scientist’s ability to get meaningful information from a well-organized data source.

  1. Data visualization

Data visualization is a graphical depiction of the results of the data analysis. To begin, you should be familiar with plots such as histograms, bar charts, and pie charts, and then go to more sophisticated charts such as waterfall charts, thermometer charts, and so on. 

These graphs are quite useful during the exploratory data analysis stage. Colorful graphics make univariate and bivariate studies much easier to grasp.

  1. Web scraping

Theoretically, any data that exists on the internet may be scrapped as needed. Companies utilize this technology to extract relevant data such as text, photos, videos, and other important information to increase productivity. 

Details might include client feedback, surveys, polls, and so on. Companies of all sizes (from start-ups to large) are actively employing this approach, and using specific tools and software for this method can ease this process 

  1. Machine learning

Predictive models are created using machine learning. You may begin with simple linear and logistic regression models and progress to sophisticated ensemble models such as Random Forest, XGBoost, CatBoost, and others. Knowing the code for these algorithms is beneficial.

  1. Deep learning

Are you inspired by smart assistants, the amazing self-driving vehicle segments? Deep learning made it all possible. Because of developments in data storage capacities and computing innovation, it is a high-growth sector in the field of Artificial Intelligence.

To flourish in this sector, you must be proficient in programming (ideally Python) and linear algebra, and mathematics. To begin, you may design simple models before progressing to more complicated models like CNN, RNN, and others.

  1. Big data

The data is generated at a rate of 2.5 quintillions each day! The advent of the internet, social media networks, and IoT has dramatically increased the amount of data we generate. This data has a high volume, velocity, and veracity, which are the three V’s of Big Data.

Organizations have been inundated with such a big volume of data, and they are attempting to deal with this data by fast embracing big data technology so that this data may be effectively maintained and accessed when needed.

  1. Software engineering

To generate high-quality code that will not cause problems during the production stage, it is required to understand the fundamentals of various software engineering topics such as the basic life cycle of computer development projects, data types, compilers, time-space complexity, and so on.
