All of the mentioned.<\/p>\n<p>A data scientist is a professional who collects, cleans, analyzes, and interprets large amounts of data. They use their findings to solve problems and make predictions.<\/p>\n<p>Data scientists typically have a background in computer science, statistics, or mathematics. They also need to have strong analytical and problem-solving skills.<\/p>\n<p>Data scientists are in high demand, as businesses are increasingly looking to data to make better decisions. The job outlook for data scientists is very good, with the Bureau of Labor Statistics projecting employment in this field to grow 27.9% from 2020 to 2030, much faster than the average for all occupations.<\/p>\n<p>Here are some of the tasks that data scientists perform:<\/p>\n<ul>\n<li>Define the question: Data scientists need to clearly define the question they are trying to answer with their data. This may involve working with stakeholders to understand their needs and goals.<\/li>\n<li>Collect data: Data scientists need to collect data that is relevant to the question they are trying to answer. This data may come from a variety of sources, such as surveys, interviews, experiments, or observational studies.<\/li>\n<li>Clean data: Data scientists need <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> to clean <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> and organize the data they have collected.
