What is a data story?Basically, a data story combines data with a storyline. It uses data as evidence to tell a meaningful tale that conveys insights or communicates a message. The goal is to make complex data accessible and relatable.
How reliable is the data in the New York Times polling data story?The reliability of the data depends on several factors. If the polling methodology is sound, like having a representative sample size and proper survey techniques, it can be quite reliable. For example, if they use random sampling across different demographics, it increases the likelihood of accurate results.

Data analysts and data analystsData analysts and data analysts were both related to data processing and analysis, but there were some differences in responsibilities.
** 1. Data analyst **
1. ** Job responsibilities **
- He was responsible for the technical management in the early stages of the project, controlling the data processing process during the project, constructing data analysis models, and assisting researchers in data analysis and mining.
- For example, in the job requirements of Guangzhou Zero Data Technology Co., Ltd., it was required to have a more comprehensive participation in the data-related work of the project, from the early stage to the management and technical support in the process.
2. ** Basic Requirements **
- Usually, bachelor's degree is required, and major in statistics or applied statistics is preferred. They needed to have relevant data analysis and mining work experience, master data analysis tools, love data work and have the spirit of research. At the same time, they also needed to have good communication and teamwork skills, as well as strong ability to withstand pressure.
3. ** Skill Requirement **
- It emphasized the full participation in the project data work process, and had certain requirements in data-related technology. It focused on basic analysis and mining work, and had certain responsibilities for the technical management of the project itself.
** 2. Data analyst **
1. ** Job responsibilities **
- Data analysts in different industries specialized in collecting, organizing, and analyzing industry data. They also made industry research, assessments, and predictions based on the data to provide recommendations to decision makers.
- For example, the data science team in the ByteDance Management Office (docking the TikTok business) should have a clear understanding of the TikTok ecosystem, and make data-driven business decisions by analyzing user behavior, author supply, and platform ecological output business cognition; Build business analysis or machine learning models and continuously optimize them; Carry out data report presentation and data product design; Meet the data needs of the business side and the team; To provide data support for strategic decisions.
2. ** Skill Requirement **
- They needed to have a deep understanding of the industry and be able to dig out valuable information from industry data for research, evaluation, and prediction. In addition to basic data analysis skills, they also needed to have the ability to build higher-level business analysis or machine learning models. They also needed to closely link data with business decisions to provide a basis for high-level decisions such as company strategies.
3. ** Current Development Status and Requirements **
- In the current job market, companies were constantly demanding data analysts. In the past, you only needed to master some basic tools such as Excel and SQL database to get a good job. However, by 2024, in addition to basic tools such as mysvl and Python, you also need to understand statistics, data cleaning, modeling, algorithms, and other knowledge. Moreover, more and more enterprises and institutions required data analysts to be certified (such as CDA certification). At the same time, due to the trend of digitizing basic positions, the competition for data analysts was more intense. If they wanted to stand out in this position, they had to be in the top 5% of the practitioners.

How can we achieve 'let the data tell the story' in data analysis?To let the data tell the story, we have to be objective. We can start by looking at the data from different perspectives. For example, we can break it down by different categories such as age groups or geographical regions. When we present the data, we should use simple and clear language. Don't overcomplicate things with too much jargon. Let the patterns and trends in the data emerge naturally. We can also compare the data with historical data or industry benchmarks to give it more context. This way, the data can effectively tell its own story without being distorted by our biases.
The Future of Data Analysis and Data EngineeringWith the acceleration of digital transformation, the demand for data analysts and data engineers continued to increase. All industries valued the value of data. From retail to finance, from medical to manufacturing, data applications were everywhere. According to a market research report, the demand for data-related positions will increase by 20% per year in the next few years, which means that they have a broad career development space.
However, the stats analyzer profession also faced some challenges. On the one hand, a large number of job opportunities were concentrated in cities such as Beijing, Shanghai, Guangzhou, and Hangzhou. These cities were filled with talent and the pressure of competition was high. On the other hand, with the popularity of artificial intelligence and machine learning technology, companies had higher requirements for data analysts. Not only must they have solid data analysis skills, but they also needed to master machine learning algorithms to deal with complex data sets. Moreover, after more than 20 years of development, many products and operating methods of the Internet have become increasingly mature. Many companies 'businesses have stabilized, and the demand for data has fallen back to "looking at data" to maintain operations. The problems that need to be solved through data analysis have drastically decreased. In recent years, technological development has spawned many data analysis and operation tools, which have lowered the threshold for product managers and operators to use data. Business personnel rely on tools to solve many problems that used to be solved by data analysts, resulting in a decrease in job demand and an increase in the threshold of existing positions. The change in the national economic cycle and the impact of the epidemic have caused many companies to live carefully. As a "high-cost" functional department, the risk of data being cut is extremely high. The promotion ceiling was obvious, and most companies had smaller teams.
The career paths of data analysts and data engineers were diverse and could meet the career planning needs of different groups of people. Data analysts could be promoted from junior analysts to senior analysts, data scientists, and even data department managers. Data scientists were the common development direction of data analysts and data engineers. This position required both professional skills. At every stage, one had to constantly learn new skills to improve their professional level.
