课程名称：Microsoft Excel - 数据分析与可视化 概述：该课程旨在帮助学习者掌握Microsoft Excel这一强大的数据分析工具。Excel是由微软开发的软件，可通过电子表格组织数字和数据，并使用公式和函数进行分析。Excel的应用遍及全球，广泛用于各类企业进行财务分析。课程专为两类学习者设计：一是对Excel几乎没有常用知识的初学者，二是希望提升自己Excel技能的常用用户。课程内容从基本操作出发，包括如何将不同格式的数据导入Excel、组织和处理数据，逐步深入到更高级的功能。 数据分析师在信息爆炸的时代中，面临着如何有效利用大量数据的挑战。数据不仅包括传统数据库中的交易数据，还有社交媒体等多个领域生成的信号。今天的零售行业收集了大量数据，跟踪用户的浏览、购买习惯等，而这些数据是企业最具战略价值的资产之一。然而，许多企业在有效利用数据上依然存在困难，不能将数据转化为有影响力的决策。 有效讲述数据背后的故事是 unlocking 数据的关键。在快节奏的商业环境中，编制准确无误的报告，能帮助企业领导决策，从而提升竞争力。只有通过数据讲述清晰的故事，决策者才能进行更好的商业决策。课程强调，拥有数据只是第一步，能够采取相应的行动才是实现变革的关键。例如，重新分配资源或及时识别失败的营销活动并调整策略，这些都是数据讲故事的重要性所在。
Excel definition: a software program created by Microsoft that uses spreadsheets to organize numbers and data with formulas and functions. Excel analysis is ubiquitous around the world and used by businesses of all sizes to perform financial analysis.The use of Excel is widespread in the industry. It is a very powerful data analysis tool and almost all big and small businesses use Excel in their day to day functioning. The course is designed keeping in mind two kinds of learners - those who have very little functional knowledge of Excel and those who use Excel regularly but at a peripheral level and wish to enhance their skills. The course takes you from basic operations such as reading data into excel using various data formats, organizing and manipulating data, to some of the more advanced functionality of Excel. As a data analyst, you are on a journey. Think about all the data that is being generated each day and that is available in an organization, from transactional data in a traditional database, telemetry data from services that you use, to signals that you get from different areas like social media.For example, today's retail businesses collect and store massive amounts of data that track the items you browsed and purchased, the pages you've visited on their site, the aisles you purchase products from, your spending habits, and much more.With data and information as the most strategic asset of a business, the underlying challenge that organizations have today is understanding and using their data to positively effect change within the business. Businesses continue to struggle to use their data in a meaningful and productive way, which impacts their ability to act.The key to unlocking this data is being able to tell a story with it. In today's highly competitive and fast-paced business world, crafting reports that tell that story is what helps business leaders take action on the data. Business decision makers depend on an accurate story to drive better business decisions. The faster a business can make precise decisions, the more competitive they will be and the better advantage they will have. Without the story, it is difficult to understand what the data is trying to tell you.However, having data alone is not enough. You need to be able to act on the data to effect change within the business. That action could involve reallocating resources within the business to accommodate a need, or it could be identifying a failing campaign and knowing when to change course. These situations are where telling a story with your data is important.
