What are the Key Steps to Analyze Data?

by Carter Toni

Data can reveal important information about users, customer bases, and markets. Data, when combined with analytics software, can assist businesses in identifying new product opportunities, marketing segments, industry verticals, and much more. A professional data analyst will spend around 70-90% of their time analyzing data. Simply not due to lack of data, but rather due to ambiguity in determining how the data should be analyzed and used leads to difficulty in analyzing data. To eliminate any doubts, businesses should thoroughly understand the entire data analysis process in order to make data-driven and informed business decisions. They can use some amazing tools like tableau that can help them presenting the analysis in more appropriate way.

Today, data analysis is critical for businesses because data-driven decisions are the only way to be truly confident in business decisions. Some successful businesses are founded on a whim, but almost all successful business decisions are data-driven. Follow Takethiscourse’s five step guide to successfully analyze data.

Why Analyzing Data is important?

Data analysis gives you more knowledge and insight into your customers, allowing you to tailor customer service to their needs, provide more personalization, and develop stronger relationships with them. Data analysis can assist you in streamlining your processes, saving money, and increasing your bottom line. When you have a better understanding of what your audience wants, you make fewer mistakes creating ads and content that isn’t relevant to their interests. Data analysis is important in business to understand problems and to explore data in meaningful ways.

What is data analysis?

Data analysis is the process of examining, cleaning, reshaping, and modeling data in order to uncover useful information, informing conclusions, and support decision-making. Data analysis has many features and frameworks, encompassing a wide range of techniques known by various names and used in a variety of business, science, and social science domains. In today’s business world, data analysis plays an important role in making decisions more scientific and assisting businesses in operating more efficiently.

What are the key steps to analyzing data?

In order to learn how to make data-driven decisions, you need to understand how to analyze data. There are a few key steps to conducting effective data analysis.

1. The first step is to define the question.

The first step in any data analysis process is to establish your goal. This is sometimes referred to as the ‘problem statement’ in data analytics terminology. Defining your objective entails developing a hypothesis and determining how to test it. Begin by asking yourself, “What business problem am I attempting to solve?” While this may appear to be a simple task, it can be more difficult than it appears. For example, your company’s senior management may raise a concern, such as “Why are we having unsatisfied clients?” However, possibly this does not address the root of the problem. A data analyst’s job is to understand the business and its goals thoroughly enough to address a problem correctly. Now that you’ve defined a problem, you must determine which data sources will best assist you in solving it. This is where your business acumen comes into play once more. Defining your goal is primarily concerned with soft skills, business knowledge, and lateral thinking. However, you must also keep track of business metrics and key performance indicators (KPIs). Monthly reports can help you track down problem areas in your business. Databox and Dasheroo, for example, charge a fee for their KPI dashboards. However, open-source software such as Grafana, Freeboard, and Dashbuilder are available. These are ideal for creating simple dashboards at the start and end of the data analysis process.

2. Data Collection

Once a purpose has been established, it is time to begin gathering the data required for analysis. This step is critical because the nature of the data sources collected determines how in-depth the analysis is. Primary sources, also known as internal sources, are used to collect data. This is usually structured data collected from CRM software, ERP systems, marketing automation tools, and other sources. These sources contain information about customers, finances, sales gaps, and other topics. Then there are secondary sources, also referred to as external sources. This includes both structured and unstructured data that can be gathered from a variety of sources. For example, if you want to conduct sentiment analysis on your brand, you could gather information from review sites or social media APIs.

3. Third step is to clean the data.

After you’ve gathered your data, the next step is to prepare it for analysis. This entails cleaning, or ‘scrubbing,’ and is critical in ensuring that you’re working with high-quality data. Among the most important data cleaning tasks are:

  • Removing big errors, replicas, and outliers—all of which are unavoidable when combining data from multiple sources.
  • Removing unnecessary data points—extracting irrelevant observations that have no bearing on the intended analysis.
  • Adding structure to your data—general ‘housekeeping,’ such as correcting typos or layout issues that will allow you to map and manipulate your data more easily
  • Completing major gaps—while cleaning up, you may notice that important data is missing. After you’ve recognized the gaps, you can work on filling them.

Manually cleaning datasets, especially large ones, can be difficult. Fortunately, there are numerous tools available to help speed up the process. Open-source tools are great for both basic data cleaning and high-level exploration. However, free tools have limited functionality when dealing with very large datasets. For heavy data scrubbing, Python libraries (such as Pandas) and some R packages are considered suitable. You will, of course, need to be familiar with the languages.

4.Conduct data analysis

Analyzing and manipulating data is one of the final steps in the data analysis process. This can be accomplished in a variety of ways.

Conduct data analysis

Data mining, which is defined as “knowledge discovery within databases,” is one method. Data mining techniques such as clustering analysis, anomaly detection, association rule mining, and others may reveal previously hidden patterns in data. There is also business intelligence and data visualization software, which are designed for decision-makers and business users. These options produce simple reports, dashboards, scorecards, and charts.

Data scientists can also use predictive analytics, which is one of the four types of data analytics used today:

  • Descriptive analysis: Descriptive analysis is used to identify what has already occurred.
  • Diagnostic analysis: Diagnostic analytics is concerned with determining why something occurred.
  • Predictive analysis: Predictive analysis uses historical data to identify future trends. The predictive analysis looks ahead in time, attempting to predict what will happen next with a business problem or question.
  • Prescriptive analysis: Prescriptive analysis allows you to make future recommendations.

Techniques for data analysis examples

Many data analysis techniques can be used by data analysts to derive meaningful information from raw data for real-world applications and computational purposes. Some notable data analysis techniques that can help with data analysis include:

Analyzing exploratory data

Exploratory data analysis is used to decipher the messages contained within a dataset. Many agile processes are used in this technique to ensure that the cleaned data is further sorted in order to better understand the useful meaning. Techniques for data visualization, such as analyzing data in an Excel spreadsheet or other graphical format, as well as descriptive analysis techniques such as calculating the mean or median are examples of exploratory data analysis.

Making use of algorithms and models

Algorithms, which include mathematical calculations for data analysis, have become an essential part of today’s data environment. Relations between data variables can be identified using mathematical formulas or models such as correlation or causal links.

Regression analysis, for example, analyses data by modeling the change in one variable caused by another. Determine whether a change in marketing (independent variable) explains a change in engagement, for example (dependent variable). Such techniques are part of  Inferential statistics, the process of analyzing statistical data to conclude the relationship between different sets of data.

5. Interpreting and sharing results:

The final step is to interpret the data analysis results. This step is critical because it is how a company will derive actual value from the previous four steps. Even if the results of your data analysis aren’t completely conclusive, they should validate why you did it.

During this process, analysts and business users should strive to collaborate. Consider any challenges or limitations that may not have been present in the data when interpreting the results. This will only increase your confidence in the coming steps.

You’ve completed your investigations. You’ve got your ideas. The final step in the data analytics process is to share these insights with the rest of the world (or, at the very least, with the stakeholders in your organization. This is more complicated than simply sharing the raw results of your work; it entails interpreting the results and presenting them in a way that all types of audiences can understand. Because you’ll be presenting information to decision-makers regularly, it’s critical that the insights you present are completely clear and unambiguous. As a result, data analysts frequently use reports, dashboards, and interactive visualizations to back up their findings.

Final word

Finally, the data analysis process or key steps implement analytical and logical arguments to extract information from the data. All of the preceding steps are primarily used to analyze data so that the resulting knowledge can be used to make critical choices.

Now you’re all set to find meaning in data!
