Education<\/h3>\n\n\n\n<p>Although there are notable exceptions, a very strong educational background is typically needed to obtain the depth of knowledge required to be a data scientist. <\/p>\n\n\n\n<p>Data scientists are highly educated; 88% have at least a Master&#8217;s degree, and 46% have PhDs. <\/p>\n\n\n\n<p>To work as a data scientist, you could obtain a bachelor&#8217;s degree in computer science, social sciences, physical sciences, or statistics. <\/p>\n\n\n\n<p>Computer science (19%), engineering (16%), mathematics and statistics (32% each) are the most popular disciplines of study. <\/p>\n\n\n\n<p>If you earn a degree in one of these programs, you will acquire the abilities necessary to process and evaluate large data. But you&#8217;re not finished yet after completing your degree program.<\/p>\n\n\n\n<p>The majority of data scientists hold a Master&#8217;s or PhD in addition to taking online courses to hone specialized skills like using<a href=\"https:\/\/nicholasidoko.com\/blog\/2022\/11\/21\/what-is-a-hadoop-cluster\/\" target=\"_blank\" rel=\"noreferrer noopener\"> Hadoop<\/a> or <a href=\"https:\/\/nicholasidoko.com\/blog\/2022\/11\/08\/what-is-big-data\/\" target=\"_blank\" rel=\"noreferrer noopener\">Big Data<\/a> searching. <\/p>\n\n\n\n<p>As a result, you can apply to master&#8217;s degree programs in various related fields, including astronomy, mathematics, and data science.<\/p>\n\n\n\n<p>You can easily transfer to data science because of the abilities you have acquired throughout your degree program.<\/p>\n\n\n\n<p>In addition to classroom instruction, you can put what you learn in the classroom into practice by creating an app, launching a blog, or dabbling in data analysis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Develop the Right Data Skills<\/h3>\n\n\n\n<p>You can still become a data scientist if you lack relevant work experience, but you will need to build the necessary foundation to pursue a career in data science.<\/p>\n\n\n\n<p>Data Science is a high-level career.<\/p>\n\n\n\n<p>Thus, before you specialize to that extent, you should have a solid foundation of expertise in a related area. <\/p>\n\n\n\n<p>This could be in mathematics, engineering, statistics, data analysis, programming, or information technology.<\/p>\n\n\n\n<p>Some data scientists have even come from backgrounds in business and baseball scouting.<\/p>\n\n\n\n<p>Mathematics, engineering, programming, statistics, data analysis, and information technology are related fields for data scientists.<\/p>\n\n\n\n<p>But no matter what area you start in, you should know <a href=\"https:\/\/www.coursera.org\/articles\/what-is-python-used-for-a-beginners-guide-to-using-python\" target=\"_blank\" rel=\"noreferrer noopener\">Python<\/a>, SQL, and Excel. <\/p>\n\n\n\n<p>These abilities will be necessary for handling and arranging raw data. Additionally, since you&#8217;ll use Tableau frequently to build visuals, it doesn&#8217;t hurt to be familiar with it.<\/p>\n\n\n\n<p>The more your experience allows you to deal with data, the more it will aid you in the following phase.<\/p>\n\n\n\n<p>So, keep an eye out for possibilities to help you begin thinking like a data scientist.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Familiarize Yourself With the Essential Data Science Tools<\/h3>\n\n\n\n<p>The data science industry uses a few well-known tools.<\/p>\n\n\n\n<p>An analytics platform called Apache Spark is used for massively scalable data engineering, processing, and machine learning. <\/p>\n\n\n\n<p>With the help of Tableau&#8217;s data visualisation tool, users may produce robust and interesting visual representations of their data connected to databases.<\/p>\n\n\n\n<p>Users might utilise the statistical software SAS to organize, analyze, forecast, and visualize data. <\/p>\n\n\n\n<p>75% of data scientists usually use the readability-focused programming language Python. <\/p>\n\n\n\n<p>47% of data scientists utilize R as their statistical programming language of choice. <\/p>\n\n\n\n<p>BigML is a well-known machine learning platform.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Get Your First Entry-Level Job as a Data Scientist<\/h3>\n\n\n\n<p>Even though there are many ways to become a data scientist, working in a relevant entry-level position is an excellent place to start. <\/p>\n\n\n\n<p>Once you&#8217;ve obtained the necessary abilities and\/or specialism, you should be prepared for your first data science position!<\/p>\n\n\n\n<p>Making an online portfolio to promote a few of your work and your achievements to prospective employers may be helpful.<\/p>\n\n\n\n<p>Since your first data science job might not include the title &#8220;data scientist,&#8221; but rather more of an analytical role, you might also want to think about a company with a possibility for progression. <\/p>\n\n\n\n<p>Consider careers as data analysts, business intelligence analysts, statisticians, data engineers, or similar jobs.<\/p>\n\n\n\n<p>You&#8217;ll pick up teamwork skills and best practices rapidly, preparing you for more senior positions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"707\" height=\"472\" src=\"https:\/\/nicholasidoko.com\/blog\/wp-content\/uploads\/2022\/10\/What-Data-Scientists-Do-How-To-Become-One.jpg\" alt=\"What Data Scientists Do &amp; How To Become One\" class=\"wp-image-20165\" srcset=\"https:\/\/nicholasidoko.com\/blog\/wp-content\/uploads\/2022\/10\/What-Data-Scientists-Do-How-To-Become-One.jpg 707w, https:\/\/nicholasidoko.com\/blog\/wp-content\/uploads\/2022\/10\/What-Data-Scientists-Do-How-To-Become-One-300x200.jpg 300w\" sizes=\"(max-width: 707px) 100vw, 707px\" \/><\/figure>\n\n\n\n<div style=\"height:35px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">5.
