What Data Analysts Do

To truly understand the data analyst role, looking at their tasks and the processes they adhere to is essential.

While data analysts’ exact duties and functions may change depending on their industry, almost all data analysts engage in certain data processing practices to gain the most value from data.

Here is what the data processing practice typically involves.

1. Collecting Data

collecting data

Before data analysts can utilize data to achieve specific goals, they must first collect it. Typically, data analysts will do this in several distinct ways.

One common source of data that most data analysts take advantage of is publicly available data. This can be data collected by government organizations or other organizations that publish their findings.

Another place data analysts typically look to collect data is through their own data collection efforts. This can include creating and conducting surveys and documenting various observations that can be used to create data sets.

The data type they collect will differ depending on what a data analyst wants to achieve. Data analysis has two distinct types: quantitative and qualitative data.

Quantitative data is data that can be translated into numerical values. In other words, it’s data that can be quantified. This form of data can come from research tools such as multiple-choice questionnaires, which offer the ability to quantify answers.

For researchers and data analysts, this form of data can sometimes be easier to work with as it is clear and distinct, which makes it ripe for analysis.

Conversely, qualitative data cannot be put into numerical values or quantified. This can include surveys that allow participants to respond to openly answered questions in which they can say whatever comes to mind.

Though this type of data and this data collection method can help point researchers in new directions and limit the role of their biases in data collection, it can be more complicated to use for analysis.

2. Storing Data

Once data analysts have collected their data, the next step is storing it securely. This refers to physical documents and digital data, which must be kept safely.

Regarding physical documents, data analysts typically use file cabinets with locks — mainly when data contains confidential information.

For digital data, data analysts typically store it in their company’s secure databases. In some cases, data analysts may also use storage devices, such as flash drives, to make additional backups to ensure that data is never lost.

3. Data Preparation

Data preparation is a stage where data analysts’ skills and expertise genuinely come into play. In this stage, these professionals must verify the accuracy of their data and prepare it for analysis.

Depending on what the analysts intend to use the data for, there will typically be other metrics and criteria they must ensure all data meets. This is a vital step for data analysis; skipping data preparation could result in faulty and inaccurate analyses.

4. Data Processing

data processing

At this stage, data analysts must process their data to prepare it for analysis. In essence, processing data is manipulating and transforming data in crucial ways to make it usable for analysis.

Processing efforts can include organizing data into distinct sets along with verifying data sets. In some cases, artificial intelligence technology is utilized to perform these functions at a high level that humans may not be capable of without the help of this technology.

5. Data Analysis

At this stage, data analysts can analyze and interpret their prepared data. This stage may look different for analysts, as what they seek will differ depending on their work industry.

The analysis will typically involve specific questions that data analysts want answers to. This can include questions such as “Which new product would consumers of a certain demographic be most willing to buy?” or “In what ways can we optimize the efficiency of a factory’s output processes?”

Analysts will also look for distinct patterns or trends in their data at this stage. Much like the data processing stage, many analysts utilize artificial intelligence technology to streamline this process and detect patterns that may be difficult or impossible for humans to interpret.

6. Data Presentation

data presentation

Once data analysts have analyzed and interpreted their data sets, they must translate the data into easily understandable representations. This can include graphic representations, such as bar graphs and pie charts, or written representations, such as reports.

This is an essential stage in the process, as data analysts must present their findings in ways that are easily understandable to others in their organization.

Those utilizing the findings will typically be in other roles, such as CEOs, marketing managers, or factory owners. As such, effectively translating data analysis findings is a crucial aspect of the data analyst role.
