  1. Aug 17, 2023 · A data analysis workflow is a step-by-step process that guides the analysis of data. It provides a structured approach to data analysis, ensuring that the process is systematic, repeatable, and scalable. The workflow typically includes several stages, each with its own set of tasks and objectives.

    • Step One: Defining The Question
    • Step Two: Collecting The Data
    • Step Three: Cleaning The Data
    • Step Four: Analyzing The Data
    • Step Five: Sharing Your Results
    • Step Six: Embrace Your Failures
    • Summary

    The first step in any data analysis process is to define your objective. In data analytics jargon, this is sometimes called the ‘problem statement’. Defining your objective means coming up with a hypothesis and figuring how to test it. Start by asking: What business problem am I trying to solve? While this might sound straightforward, it can be tri...

    Once you’ve established your objective, you’ll need to create a strategy for collecting and aggregating the appropriate data. A key part of this is determining which data you need. This might be quantitative (numeric) data, e.g. sales figures, or qualitative (descriptive) data, such as customer reviews. All data fit into one of three categories: fi...

    Once you’ve collected your data, the next step is to get it ready for analysis. This means cleaning, or ‘scrubbing’ it, and is crucial in making sure that you’re working with high-quality data. Key data cleaning tasks include: 1. Removing major errors, duplicates, and outliers—all of which are inevitable problems when aggregating data from numerous...

    Finally, you’ve cleaned your data. Now comes the fun bit—analyzing it! The type of data analysis you carry out largely depends on what your goal is. But there are many techniques available. Univariate or bivariate analysis, time-series analysis, and regression analysis are just a few you might have heard of. More important than the different types,...

    You’ve finished carrying out your analyses. You have your insights. The final step of the data analytics process is to share these insights with the wider world (or at least with your organization’s stakeholders!) This is more complex than simply sharing the raw results of your work—it involves interpreting the outcomes, and presenting them in a ma...

    The last ‘step’ in the data analytics process is to embrace your failures. The path we’ve described above is more of an iterative process than a one-way street. Data analytics is inherently messy, and the process you follow will be different for every project. For instance, while cleaning data, you might spot patterns that spark a whole new set of ...

    In this post, we’ve covered the main steps of the data analytics process. These core steps can be amended, re-ordered and re-used as you deem fit, but they underpin every data analyst’s work: 1. Define the question—What business problem are you trying to solve? Frame it as a question to help you focus on finding a clear answer. 2. Collect data—Crea...

  2. Nov 17, 2023 · Dataflow allows users to create a model of their application’s data flow using a graphical tool called “data flow diagrams” (DFDs). These diagrams show all the steps in the application’s process, including where each piece of data comes from, where it goes, and what happens during each step. 2. Data Pipeline.

  4. Mar 11, 2024 · A data science workflow defines the phases (or steps) in a data science project. Using a well-defined data science workflow is useful in that it provides a simple way to remind all data science team members of the work to be done to do a data science project. One way to think about the benefit of having a well-defined data science workflow is ...
