Web Scraping

Web scraping is the process of collecting data from web pages. There are different web scraping techniques, but most professionals utilize computer bots. This technique is faster and less prone to error than manual data discovery.

Remember that while screen scraping and web scraping are often used interchangeably, they’re not the same. The former merely copies screen pixels after recognizing them from various user interface components. The latter is a more extensive procedure that recovers the HTML code and any information stored within it.

Data Acquisition

Data acquisition is a form of data collection that garners information before storing it on your cloud-based servers or other solutions. Companies can collect information with specialized sensors and other devices. This equipment makes up their data acquisition systems.

Data Cleaning

You only need usable and original information in your system. Duplicate and redundant data can be a major obstacle, which is why you should use data cleaning. It removes contradictory information and helps you separate the wheat from the chaff.

Data Preprocessing

Data preprocessing prepares your data sets for other processes. Once it’s done, you can move on to information transformation, normalization, and analysis.

Data Transformation

Data transformation turns one version of information into another. It transforms raw data into usable information.

Data Normalization

You can’t start your data analysis without normalizing the information. Data normalization helps ensure that your information has uniform organization and appearance. It makes data sets more cohesive by removing illogical or unnecessary details.

Data Analysis

The next step in the data science lifecycle is data analysis. Effective data analysis provides more accurate data, improves customer insights and targeting, reduces operational costs, and more. Following are the main types of data analysis:

Exploratory Data Analysis

Exploratory data analysis is typically the first analysis performed in the data science lifecycle. The aim is to discover and summarize key features of the information you want to discuss.

Predictive Analysis

Predictive analysis comes in handy when you wish to forecast a trend. Your system uses historical information as a basis.

Statistical Analysis

Statistical analysis evaluates information to discover useful trends. It uses numbers to plan studies, create models, and interpret research.

Machine Learning

Machine learning plays a pivotal role in data analysis. It processes enormous chunks of data quickly with minimal human involvement. The technology can even mimic a human brain, making it incredibly accurate.

Data Visualization

Preparing and analyzing information is important, but a lot more goes into data science. More specifically, you need to visualize information using different methods. Data visualization is essential when presenting your findings to a general audience because it makes the information easily digestible.

Data Visualization Tools

Many tools can help you expedite your data visualization and create insightful dashboards.

Here are some of the best data visualization tools:

  • Zoho Analytics
  • Datawrapper
  • Tableau
  • Google Charts
  • Microsoft Excel

Data Visualization Techniques

The above tools contain a plethora of data visualization techniques:

  • Line chart
  • Histogram
  • Pie chart
  • Area plot
  • Scatter plot
  • Hexbin plots
  • Word clouds
  • Network diagrams
  • Highlight tables
  • Bullet graphs

Data Storytelling

You can’t have effective data presentation without next-level storytelling. It contextualizes your narrative and gives your audience a better understanding of the process. Data dashboards and other tools can be an excellent way to enhance your storytelling.

Data Interpretation

The success of your data science work depends on your ability to derive conclusions. That’s where data interpretation comes in. It features a variety of methods that let you review and categorize your information to solve critical problems.

Data Interpretation Tools

Rather than interpret data on your own, you can incorporate a host of data interpretation tools into your toolbox:

  • Layer – You can easily step up your data interpretation game with Layer. You can send well-designed spreadsheets to all stakeholders for improved visibility. Plus, you can integrate the app with other platforms you use to elevate productivity.
  • Power Bi – A vast majority of data scientists utilize Power BI. Its intuitive interface enables you to develop and set up customized interpretation tools, offering a tailored approach to data science.
  • Tableau – If you’re looking for another straightforward yet powerful platform, Tableau is a fantastic choice. It features robust dashboards with useful insights and synchronizes well with other applications.
  • R – Advanced users can develop exceptional data interpretation graphs with R. This programming language offers state-of-the-art interpretation tools to accelerate your projects and optimize your data architecture.

Data Interpretation Techniques

The two main data interpretation techniques are the qualitative method and the quantitative method.

The qualitative method helps you interpret qualitative information. You present your findings using text instead of figures.

By contrast, the quantitative method is a numerical data interpretation technique. It requires you to elaborate on your data with numbers.

Data Insights

The final phase of the data science process involves data insights. These give your organization a complete picture of the information you obtained and interpreted, allowing stakeholders to take action on company problems. That’s especially true with actionable insights, as they recommend solutions for increasing productivity and profits.

Climb the Data Science Career Ladder, Starting From the Basics

The first step to becoming a data scientist is understanding the essence of data science and its applications. We’ve given you the basics involved in this field – the rest is up to you. Master every stage of the data science lifecycle, and you’ll be ready for a rewarding career path.
