Model Building<\/strong><\/p>\n<p>Data Science is a process that involves extracting knowledge and insights from data. It is a multidisciplinary field that combines statistics, computer science, and machine learning. The data science process can be divided into the following steps:<\/p>\n<ol>\n<li><strong>Data Collection<\/strong><\/li>\n<\/ol>\n<p>The first step in the data science process is to collect data. This data can be collected from a variety of sources, such as surveys, interviews, experiments, and observational studies.<\/p>\n<ol>\n<li><strong>Data Cleaning<\/strong><\/li>\n<\/ol>\n<p>The next step is to clean the data. This involves removing any errors or inconsistencies in the data.<\/p>\n<ol>\n<li><strong>Data Analysis<\/strong><\/li>\n<\/ol>\n<p>The third step is to analyze the data. This involves using statistical methods to identify patterns and trends in the data.<\/p>\n<ol>\n<li><strong>Model Building<\/strong><\/li>\n<\/ol>\n<p>The fourth step is to build a model. This involves using machine learning algorithms to create a model that can predict future outcomes.<\/p>\n<ol>\n<li><strong>Model Evaluation<\/strong><\/li>\n<\/ol>\n<p>The fifth step is to evaluate the model. This involves testing the model to see how well it performs on unseen data.<\/p>\n<ol>\n<li><strong>Model Deployment<\/strong><\/li>\n<\/ol>\n<p>The sixth step is to deploy the model. This involves making the model available to users so that they can use it to make decisions.<\/p>\n<ol>\n<li><strong>Model Monitoring<\/strong><\/li>\n<\/ol>\n<p>The seventh and final step is to monitor the model. This involves tracking the performance of the model over time and making changes as needed.<\/p>\n<p>In the question, the step that involves building and training predictive models is <strong>Model Building<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Data Collection&#8221;
