What does the data science process look like?

Normally, the data science process consists of five steps: data collection, data cleaning, data analysis, model creation and deployment, and results communication.

Let’s take a look at each stage in greater detail.

Data collection

It is essential to understand and be able to explain what exactly you are planning to achieve with data science. You should also have a list of questions and aspects of your business you are eager to enhance with the help of data.

Once you are done with this, your team of data scientists can get down to collecting the necessary sets of data from all identified internal and external sources, including social media, web servers, or data retrieved from online sources via APIs.

Data cleaning

The collected data may be unfiltered and unstructured, with high levels of inconsistencies and incorrect formats. All these issues will need to be cleaned to safeguard the accuracy of predictions.

The data cleaning process includes the removal of duplicates, inconsistent data values, invalid entries, null values, and so on.

Data analysis

Once all the data has been cleaned and organized, it is time to perform an exploratory data analysis. This will help you get valuable and actionable information that will be used throughout the upcoming data science process.

Model creation and deployment

When the data has been analyzed, you can proceed with the actual data modeling, wherein data scientists allocate datasets for training and testing. During this step, data scientists adopt techniques such as association, classification, and clustering to get the most accurate insights and predictions.

Afterwards, the model is subject to exhaustive testing and is then ready to be deployed in the production environment. This step implies the creation of a delivery mechanism to present the model to users or to another system.

Results reporting

Finally, all the findings can be reported to stakeholders. It is mandatory to present the findings in an understandable fashion, accompanying them with clear and accurate data visualizations and graphics.
