Below is a breakdown of some of the essential technical skills required for data science, broken into three subcategories - statistical skills, mathematical skills, and programming abilities needed by Data Scientists.
Statistical and Probability Skills
Thinking in statistics is central to data science; you cannot become a Data Scientist without possessing this expertise. Data Science is simply another name for statistics!
While traditionally, only those with degrees in Statistics could study Data Science, nowadays, anyone can do it. There are numerous books that offer statistical insights about data Science as well as teaching practical aspects of it.
As part of your data science journey, we will introduce some key statistical concepts. Statistics are generally divided into two categories - descriptive statistics and inferential statistics.
Descriptive Statistics is concerned with summarizing and describing data. It quantifies large features of data through visualizations while outlining samples from larger populations of values. Some measurements used in descriptive statistics include normal distribution, variability, kurtosis & skewness and central tendency.
Inferential statistics is about drawing inferences or inferences from data, concluding smaller samples to generalize over a wider population. Various statistical methods are involved with inferential statistics, which must be familiar to you to succeed in this process. Some methods include Central Limit Theorem, Hypothesis Testing, ANOVA and Quantitative Data Analysis - essential techniques that will equip you with all the statistics skills.
An essential skill needed to become a data scientist is Probability. Probability concepts form the backbone of data science and must be grasped to carry out complex machine-learning operations effectively. They're used for inferential statistics as well as creating Bayesian Networks.
As machine learning algorithms like Naive Bayes rely heavily on conditional probability, you must also become adept in its usage. Conditional probability allows you to determine the uncertainty and risks surrounding events, enabling more informed decisions that benefit your company.
Stats and Probability both play an essential part in being a Data Scientist.

Ability to Handle Massive Amounts of Data
Data production has seen exponential growth since 2009, most of which falls into the unstructured category.
Unstructured data refers to information that does not reside in a traditional row-column database; examples include videos, photos and audio messages. As data scientists seek meaning from this massive amount of information regardless of its form, dealing with structured and unstructured forms should be fine.
Data Visualization
As companies generate more and more data, it must be presented in an easily understandable format in order to make decisions effectively. As a data scientist, one must be adept at Data visualizing that data using tools like Tableau, Plotly, Visual.ly, D3.js and Power BI; also crucial is knowing the principles behind visually organizing it together - one of their key roles as organizations directly engage with data via visualization.
Programming Skills
Excel might have sufficed 20 years ago when dealing with structured and unstructured data generation. Still, due to today's vast volume of structured and unstructured information originating, data scientists should possess programming tools such as Python and R. They offer more flexibility for training the data set with various statistical techniques and improving analysis process efficiency.
Data Manipulation
Too often, the data we need to be more organized for data scientists to work with effectively. After extracting it from data lakes, the first step should be addressing any imperfections present - missing values, irregular strings such as LA for Los Angeles and date formats that change, such as 10/09/2009 to 2009/09/10 must all be eliminated before commencing training or analysis.
Data Wrangling
Sometimes Data Scientists must deal with incomplete or messy data sets that are initially incomprehensible or useless for further processing. In such a case, Data Wrangling involves cleaning and reformatting this unusable information into an accessible format to make sense to users and be understood.
