Top Five Essential Data Scientist Skills
Data scientists collect, analyze, and interpret data to gain insights and solve evidence-based problems. To achieve this, they combine their acquired knowledge and skills in statistics, probability, deep learning, business intelligence, and computer science.
Data scientists typically collaborate with other key stakeholders and departments. For instance, they work with the software development and data engineering department to build data pipelines, database architecture, machine learning models, and many more tools to optimize the business.
In that light, you will need relevant technical skills alongside several soft skills to succeed in the field. Below, you will find some crucial skills data science professionals need to possess.
1. Statistics and Mathematics Skills
Data science employs various statistical techniques and mathematical concepts to prepare, arrange, and process large and unstructured data sets into understandable forms. Z-score, among other statistical measures, is also helpful in data cleaning and detecting anomalies present in the data set.
Other statistical methods a data scientist should be familiar with include data collection, probability calculations, exploratory data analysis, and A/B statistical testing.
2. Programming Skills
Data scientists use various programming languages to build data pipelines, business intelligence systems, machine learning models, and databases. Also, they automate data collection, organization, and database implementation processes through a wide range of coding skills. Some common languages used by data scientists include Python, SQL, Perl, C, and Java.
3. Data Analysis Skills
Data scientists spot trends and generate key business insights from large data sets through analytics tools and skills. Predictive analytics assists them in predicting the possibility of future events, while diagnostic and prescriptive analytics help to answer evidence-based problems.
4. Effective Presentation and Communication Skills
Data scientists deliver their findings to important business stakeholders using easy-to-understand tools such as graphs, charts, infographics, and video illustrations. This is why excellent communication skills are essential for anyone looking to step into this field. As a data scientist, you must be able to communicate your ideas effectively with all stakeholders regardless of their technical background.
5. Problem-Solving Skills
Data scientists face distinct challenges daily, ranging from data preparation to data security, system development, and more. Excellent problem-solving and critical-thinking skills help them to find creative and efficient solutions to these challenging data science problems.
