Data Science Training Provides Hot Dip Topics That Is Relevant To Data And Data Science


    Data science is called the 21st century’s sexiest job. With the plethora of data that gets created today, it has become important for businesses and organizations to draw useful insights from them, which can help them make data-driven decisions. According to a report by DOMO, every single day, more than 2.5 quintillion bytes of data get created. This is set to grow as by 2020, 1.7MB of data is estimated to be created each second for each person on earth. Thus, there’s no shortage of data out there. However, getting the ability to access it and leverage it by acting on it – wherever, whenever, and however you need, is a different ballgame altogether. And since data science facilitates this, it has emerged as one of the hot dip topics in the modern era.

    There’s a plethora of data that gets generated every second. This includes your social media activities that trigger data creation in massive amounts, your communication modes (sending text or emails, making Skype calls, sending GIFs via Facebook messenger, Tinder swipes, etc.), your online purchases, the digital photos stored on your smartphones, or the statistics generated by businesses and service providers (such as trip details on Uber, songs added on Spotify, peer-to-peer transactions processed by Venmo, page edits made on Wikipedia, etc.), among others. Sitting on this stockpile of data won’t help businesses unless they can spot trends, predict future demands, and leverage such insights to make proactive business decisions. Since data science professionals can help make sense of such data – be it structured and unstructured, there’s a huge demand for them across industries and verticals.

    Perhaps this explains why there’s almost a mad rush to get enrolled in data science training courses. Despite the domain being a much coveted one, especially as it offers high-paying jobs, you should know that it won’t be a cakewalk to learn. So, if you perceive it to be an easy road, you should think twice before joining a data science training program. If you thought it would just need jumping on a data science training session to learn and basics and then become an expert, you are far from reality. You should be ready to work hard and remember that the most important thing you need to succeed in this field is depth, not just breadth. What this means is once you got the basics right, you need to choose your favorite domains and specialize. For example, some data scientists decide to delve deeper into operations and learn to tweak Apache Spark (the analytics engine) in detail.

    All these shouldn’t sound discouraging because if you are really passionate about data science and are ready to invest adequate time and effort to learn and master some hot dip topics, you should definitely go ahead and join a suitable course that has the modules or course content to meet your learning and career goals.

    Hot Dip Topics of a Data Science Training

    If the data science landscape sounds fascinating to you and you plan to get enrolled into some data science training courses or bootcamps, here are some hot dip topics that you should aim to learn and master.

    1- Fundamentals of Statistics

    Knowing the concepts of statistics is the key to being a data scientist or data analyst, irrespective of the language or tool you decide to use in the process. If you have a Mathematics or Statistics background, you should join a data science training program that helps you brush up on your knowledge. But if you aren’t from either of these fields, you should opt for a data science training course that covers topics such as probability, descriptive statistics, distributions, hypothesis testing, estimation, inference, regression, etc.

    Once you have learnt the basics, you should proceed to advanced tools, which could include the following:

    • Probability value
    • General linear model
    • Central Limit Theorem
    • Time Series Analysis
    • Under and over Sampling

    You should also learn about statistical methods such as Z/t-tests (independent, one sample, paired), correlations and Chi-square, Anova (analysis of variance), etc. Additionally, your data science training course should teach you the important modules for statistical methods such as NumPy, Pandas, SciPy, etc.

    To learn and master hot dip topics related to data science, having adequate knowledge of statistics is a must.

    2- Python

    This is one of the hot dip topics in the domain of data science. If you don’t have any programming background, you should take up data science training courses that teach you the basics of Python. This would usually include getting familiar with the data types, basic programming syntax, and programming building blocks using Python. Even if you are a programmer, who has been using other languages, learning the basics of Python at first would be a good choice.

    Usually, data science training modules aiming to teach the essentials of Python will cover:

    • An overview of Python followed by its installation
    • Getting started with Python Editors & IDE’s (PyCharm, Canopy, Jupyter, IPython, Rodeo, etc.)
    • Understanding the concept of Libraries/Packages and learning about important packages (such as NumPy, SciPy, scikit-learn, Matplotlib, Pandas, etc.)
    • Learning about data objects/structures (strings, sets, tuples, lists, dictionaries) as well as data types
    • Dictionary and list comprehensions
    • Value labels and variables – time and date values
    • Reading and writing data
    • Understanding the basic operations – Mathematical – date – string
    • Control flow statements and conditional statements
    • Simple plotting
    • Code profiling and debugging

    In case you already have a rock solid knowledge of the basics of Python, you can opt for advanced modules to data science with Python, which could include

    • Scientific distributions uses in Python for data science such as NumPy, SciPy, Pandas, scikit-learn, NLTK, statsmodels, etc.
    • Importing/accessing and exporting data using Python modules
    • Using Python modules for data cleansing, manipulation, and munging
    • Using Python modules for data analysis and visualization

    If you are wondering why you should learn data science with Python, the answer lies in the advantages this programming language brings your way. Some of these are:

    • Python is an open source programming language. Thus, this powerful programming language is free to use and has a robust community that works continuously to make it better and offers help to those who need it.
    • This versatile and powerful programming language supports functional programming, structured programming, and OOP (Object-Oriented Programming) patterns.
