Businesses continue to struggle to use this data in a meaningful and productive way.<\/p>\n<p style=\"outline-color: inherit; margin-top: 1rem; color: rgb(22, 22, 22); font-family: &quot;Segoe UI&quot;, SegoeUI, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;\">A retail business should be able to use their vast amounts of data and information in such a way that impacts the business, including:<\/p><ul style=\"box-sizing: inherit; outline-color: inherit; margin-top: 16px; margin-bottom: 16px; margin-left: 38px; list-style-type: none; color: rgb(22, 22, 22); font-family: &quot;Segoe UI&quot;, SegoeUI, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;\"><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\"><span style=\"font-size: 1rem;\">Detecting user trends and patterns<\/span><\/li><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\">Recommending purchases<\/li><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\">Identifying and stopping fraud<\/li><li><\/li><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\">Identifying purchase habits<\/li><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\">Tracking inventory<\/li><li><\/li><li><\/li><li style=\"outline-color: inherit; outline-style: initial; outline-width: 0px; list-style: disc;\">Determining price optimizations<\/li><\/ul>\n<font\u00a0color=\"#161616\" face=\"Segoe UI, SegoeUI, Helvetica Neue, Helvetica, Arial, sans-serif\"><p style=\"outline-color: inherit; margin-top: 1rem; color: rgb(22, 22, 22); font-family: &quot;Segoe UI&quot;, SegoeUI, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;\">However, having data alone is not enough. You need to be able to act on the data. Reallocating resources within the business, or knowing when to transform the data to suite the situations are where telling a story with your data is important.<\/p><p style=\"outline-color: inherit; margin-top: 1rem; color: rgb(22, 22, 22); font-family: &quot;Segoe UI&quot;, SegoeUI, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;\">Your first step is to partner with data experts within your organization, such as data engineers and data scientists, to help get the data that you need to tell that story. Ask these experts to participate in that data journey with you.<\/p><p style=\"outline-color: inherit; margin-top: 1rem; color: rgb(22, 22, 22); font-family: &quot;Segoe UI&quot;, SegoeUI, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif;\"><span style=\"font-size: 1rem;\">Data analysis exists to help overcome these challenges and pain points, ultimately assisting businesses in finding insights and uncovering hidden value in troves of data through storytelling. As you read on, you will learn how to use and apply analytical skills to go beyond a single report and help impact and influence your organization by telling stories with data and driving that data culture.<\/span><\/p><\/font\u00a0color=\"#161616\">\n\n\n\n\n\n\n\n\n\n\n\n<p><strong>\n\n\n\n\nOverview of Data Analysis\n<\/strong><\/p>\n<p><ul><li>\n\n\n\n\nDefinition and importance of data analysis\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nTypes of data: structured vs unstructured\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nThe data analysis process\n<\/li><\/ul><\/p>\n<p><strong>\n\n\n\n\n\n\nData Collection Methods\n<\/strong><\/p>\n<p><ul><li>\n\n\n\n\nPrimary vs secondary data\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nSurveys, experiments, and observational studies\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nEthical considerations in data collection<\/li><\/ul><\/p>\n\n\n\n\n\n\n\n<h4 id=\"bh-_JVONeh4Wb8lKocQJC8An\" data-hook-type=\"blockHook\" dir=\"ltr\" data-bubble-menu=\"true\" data-pm-slice=\"1 5 []\">Data Preparation<\/h4>\n<p><strong>Data Cleaning\n<\/strong><\/p>\n<p><ul><li>Identifying and handling missing data\n<\/li><\/ul><\/p>\n<p><ul><li>\nOutlier detection and treatment\n<\/li><\/ul><\/p>\n<p><ul><li>\nData transformation techniques<\/li><\/ul><\/p>\n<strong>Data Wrangling\n<\/strong>\n<p><ul><li>Introduction to data wrangling\n<\/li><\/ul><\/p>\n<p><ul><li>Using tools like Pandas for data manipulation\n<\/li><\/ul><\/p>\n<p><ul><li>Merging and reshaping datasets<\/li><\/ul><\/p>\n\n\n\n\n\n\n\n\n\n\n<h4 id=\"bh-l21pR3WYx8SrxoEt4KhMP\" data-hook-type=\"blockHook\" dir=\"ltr\" data-bubble-menu=\"true\" data-pm-slice=\"1 5 []\">Data Visualization<\/h4>\n<strong>Principles of Data Visualization\n<\/strong>\n<p><ul><li>\nImportance of data visualization\n<\/li><\/ul><\/p>\n<p><ul><li>\nCommon visualization types and when to use them\n<\/li><\/ul><\/p>\n<p><ul><li>\nBest practices for effective visual communication<\/li><\/ul><\/p>\n<strong>Visualization Tools\n<\/strong>\n<p><ul><li>\n\n\nIntroduction to visualization tools (e.g., Matplotlib, Seaborn, Power BI, Tableau, Google Looker Studio)\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nCreating basic plots and charts\n<\/li><\/ul><\/p>\n<p><ul><li>\n\n\nAdvanced visualization techniques<\/li><\/ul><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":"","footnotes":""},"categories":[29],"tags":[],"class_list":["post-117","post","type-post","status-publish","format-standard","hentry","category-data-analysis"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.8 -
