What is Data Analysis?

Analyzing data helps businesses make more informed decisions. Analyzing data typically involves five iterative phases:

  • Identify the data you want to analyze
  • Collect the data
  • Clean the data in preparation for analysis
  • Analyze the data
  • Interpret the results of the analysis

Different types of data analysis can be used to answer various questions. More information about data analysis can be found here. The descriptive analysis tells us what happened, the diagnostic research suggests why, the predictive analysis makes projections about the future, and the prescriptive analysis provides actionable recommendations.

Who is a Data Analyst?

The data analyst collects, processes, and analyzes large datasets. All businesses generate and collect data, regardless of their size. Data may include customer feedback, account information, logistics, marketing research, etc. 

Data analysts analyze data to find ways to improve customer experiences, price new materials, and reduce transportation costs. A data analyst handles data, models it, and reports it. 

Once you know who is data analyst? It’s paramount to understand the roles and responsibilities of a data analyst.

The Role of Data Analytics

By pinpointing patterns, data analytics can improve operations, efficiency, and performance in numerous industries. Implementing these techniques can give businesses and companies an advantage over their competitors. There are four steps to the analysis process.

Data Mining

As the name implies, this step gathers data and information from various sources. It is then necessary to recreate multiple forms of communication in the same format to analyze them. There is no doubt that this process takes a good deal of time, more than any other.

Data Management

A database contains, manages, and allows access to the information gathered through data mining. In data analytics, the next step is to create a database to collect the data. In the early days of data analytics, SQL was a standard tool for this purpose, and it remains so in 2023. This computing language allows relational databases to be queried, and the resulting data sets can be analyzed more easily.

Statistical Analysis

The third step is to conduct a statistical analysis. Data is analyzed into models that reveal trends that can be used to interpret future data based on the gathered and stored data. Python is an open-source programming language that accomplishes this. In addition to statistical analysis and graphical modeling, specific tools for data analytics, such as R, can be used.

Data Presentation

Data analytics results should be shared. The final step is to format the data so it can be accessed and understood by others, particularly those responsible for growth, analysis, efficiency, and operations. It can also be beneficial for shareholders to have access.  

Types of Data Analysts

Depending on your interests and skill set, several Data Analyst roles are available. The following are some common types of Data Analysts:

Business/Data Analyst

Data Analysts help companies make informed decisions by collecting, analyzing, and interpreting complex data sets. Business requirements are identified, and supporting data models are designed closely with stakeholders. In addition, they may provide data insights to decision-makers through reports and dashboards.

Marketing Analyst

Market analysts help companies understand their customers and develop marketing strategies based on data. Analyzing customer behavior, demographics, and market trends can help companies target their marketing efforts effectively. It is also possible to measure the success of a marketing campaign using a marketing performance metric.

Financial Analyst

Financial Analysts use data to assist companies in making financial decisions. Companies may use financial data to identify areas for improvement or growth by analyzing revenue, expenses, and profitability. Additionally, economic models may be developed to forecast future performance and inform strategic planning.

Healthcare Analyst

Healthcare Analysts assist healthcare organizations in improving patient outcomes and reducing costs. A healthcare analyst analyzes patient records, clinical trials, and insurance claims to identify patterns and trends. They can also develop predictive models to assist healthcare providers in making more informed decisions.

Data Scientist

Data Scientists design and develop complex algorithms to solve data-driven problems. Using advanced analytical techniques, they extract insights from large, complex data sets and develop predictive models. Additionally, Data Analysts may collaborate to create data-driven solutions for businesses.

Data Analyst Qualifications and Prerequisites

Data analysts must possess a few essential qualifications and prerequisites to be successful. It is essential for data analysts to have excellent mathematical skills and be able to analyze data sets efficiently. 

Second, they should be familiar with statistical software packages such as SAS, R, and SPSS. Lastly, data analysts should be able to communicate effectively with clients or other stakeholders about their findings. In this capacity, data analysts can provide valuable insights that can improve an organization’s performance and excel in their role.

Data Analyst Tasks and Responsibilities

Data analysts gather and interpret data to solve a specific problem. It involves a lot of time spent with data but also communicating findings. 

Among the many things that data analysts do on a day-to-day basis are:

  • Gather data: Data is often collected by analysts themselves. Conduct surveys, track visitor characteristics on a company website, or buy datasets from data collection specialists.
  • Clean data: Raw data may contain errors, duplicates, or outliers. Cleaning the data ensures your interpretations will be accurate. 
  • Model data: In this process, the structure of a database is created and designed. It is possible to select the types of data to store and collect, determine how the data categories are related, and determine how the data is presented.
  • Interpret data: Data interpretation involves finding patterns or trends that could provide answers to questions.
  • Present: Communicating your research findings will be key to your job. In addition to creating visualizations like charts and graphs, you also write reports and present information to interested parties.

Data Analyst Salary

Data analysts can earn high salaries, and their earnings can increase with experience. 

According to Glassdoor, approximately $64,000 annually is the average salary for entry-level data analyst jobs with 0-1 years of experience. The average analyst earns over $75,000 annually in the United States. An experienced data analyst can command a six-figure yearly salary of about $100,000. It is possible to make as much as $157,000 at the top end of the scale.

Mattmann states this field has even higher salary potential in specific industries. The median salary for entry-level data analyst positions in government is $120,000 to $140,000, and the median wage for commercial roles is double that with equity. Typically, government jobs pay between $180,000 and $200,000. Commercial jobs may pay double that, depending on equity.

According to the Labor Statistics Bureau (BLS), the job outlook for operations research analysts (including data analysts) is very good.
