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.

It depends. If they used proper sampling methods and had a large enough sample size, it can be quite reliable. But there are always some margins of error.

Data 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 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. "When a programmer meets a psychologist" is equally exciting. Everyone is welcome to click to read it!
