But there isnโ€™t nearly as much content that describes what data scientists do on the job. Today, weโ€™ll address this topic. Contrary to what many business stakeholders believe, a data scientist isnโ€™t a magician who can use AI to fix any problem. A data scientistโ€™s primary purpose isnโ€™t to pull data from the database either . A company that thrivesโ€”thanks to its data scientistsโ€”can educate those within the organization that a data scientistโ€™s primary goal is to create business value by using data . A data scientistโ€™s role encompasses different activities, many of which we will describe in this video. Still, the first and most crucial point we need to remember is that the end goal of each task of a data scientist is to create business value. Thereforeโ€”besides solid statistics knowledge and an ability to use such coding languages as Python, R, and SQLโ€”data scientists need business and communication skills to be successful in their work . 00:00-00:36 Intro to the story 00:36-00:51 Talking to stakeholders 00:51-01:15 Reformulating the problem 01:15-01:41 Simpler solution 01:41-02:58 Formulating a hypothesis and A/B testing 02:58-03:46 Exploratory data analysis (EDA) 03:46-04:24 Second A/B test 04:24-04:50 ML Brainstorming 04:50-05:16 Machine learning mechanics 05:16-05:41 ML Fine-tuning 05:41-05:58 ML Engineering 05:58-06:05 ML A/B test 06:05-06:39 Conclusion โ–บ Consider hitting the SUBSCRIBE button if you LIKE the content: https://www.youtube.com/c/365DataScience?sub_confirmation=1 โ–บVISIT our website: https://bit.ly/365ds ๐Ÿค Connect with us LinkedIn: https://www.linkedin.com/company/365
