Statistical analysis is a crucial component of any data science process. You’ll be able to make sense of large amounts of data, discover patterns and explain results in a meaningful way. It’s also helpful to understand how to turn data into information and how to use tools to handle various data types.

Depending on your degree, you could find yourself with a concentration in analytics, statistics, or a more specific subfield, like biostatistics. This can help you narrow your focus and avoid overgeneralizing or getting lost in the breadth of the field. There are plenty of opportunities to hone your statistical skills as a data scientist. You could offer consulting services, conduct research, or even run your own company.

Statistical analysis for data science involves the use of statistics to examine and understand the data. For example, it may include techniques for identifying patterns and correlations in data, hypothesis testing, and designing experiments to verify or disprove hypotheses. You’ll hone in on skills such as descriptive statistics, inferential statistics, and regression analysis.

  • Identifying patterns and trends
  • Making predictions from the data
  • Interpreting the data
  • Drawing conclusions
  • Examination of correlations between variables
  • Determination of relationships between variables
  • Estimation of parameters

Once you have the data you need, you’ll need to analyze it. This might involve visualizing the data, drawing conclusions from it, or looking for patterns and trends. You’ll also need to make sense of the data’s structure and determine appropriate methods for processing it.

As such, you could focus your education on data analysis, business analytics, or statistics-related fields. Whichever you choose, make sure you’re up to speed on the latest methodologies and tools. This will give you an edge in your current job and also help you find new opportunities down the line.

Data analysts collect, organize, and analyze data to derive insights that help organizations make informed decisions. They may use a variety of tools and techniques to get the data they need, including data mining, data analysis, and data visualization.

  • Organizing, analyzing, and interpreting data
  • Use techniques such as regression analysis, cluster analysis, and data mining to identify trends and patterns
  • Help organizations make better decisions
  • Identify potential problems, or recommend solutions
  • Use various statistical and mathematical techniques to understand patterns and trends in data

3. Data Engineering

Data engineering involves using tools like Hadoop and Apache Spark to process and store large amounts of data. You can use these tools to process data quickly, store the data in a durable fashion, and serve it to other systems.

This is a crucial role in any data-driven organization, which needs data engineers to build pipelines and make use of ETL processes. It’s also helpful to have experience in one of the related fields.

  • Data modeling – creating a process for data that will be used to store, retrieve, and manage information.
  • Big data – Big data is a term used to describe data that is too large or complex to be handled by traditional data management systems.
  • Data warehousing – The practice of creating a system to store, manage, and analyze data that is used to improve business operations.
  • ETL – An ETL pipeline is a collection of scripts and tools used to transform data from one format to another.
  • Data preprocessing and cleansing – Preprocessing and cleansing refer to any steps taken before data is used in the analysis. Preprocessing may include data cleaning, data analysis, and data pre-processing.
  • Data cleansing – Cleansing may include removing impurities, outliers, and inaccuracies from data. Analysis may include statistical analysis, data visualization, and data interpretation.

4. Business Intelligence

Business intelligence is a broad term that covers a variety of data science tasks. You might analyze data to discover insights into customers’ needs and preferences, recommend improvements to operations, or build custom tools for internal use. 

Depending on your degree, you could find yourself in one of the following roles: a BI analyst, BI engineer, or data scientist. This is a great option for those with a business background or who are proficient in tools like SQL or Python.

It’s also helpful if you like working with data and creating solutions for real-world problems. If you want to stay current in an industry that’s growing quickly, consider one of the many business intelligence specializations available.

  • Informing decision-making, improving performance, and understanding customer behavior
  • Collection, interpretation, and use of data from different sources
  • Provides analytics, reporting, and data management capabilities
  • Use data and how to improve business processes
  • Track, analyze, and report on your company’s performance and operations
  • Spot trends, and optimize performance

5. Machine Learning

Machine learning is a subset of artificial intelligence that allows computers to learn from data without being explicitly programmed. By analyzing large sets of data and then applying algorithms to that data, machine learning allows computers to make predictions and recommendations.

Although machine learning and data science are similar fields, machine learning focuses on creating computer algorithms that can make predictions based on data. This can involve creating models that can predict outcomes like click volume for a certain webpage, or analyzing voice data to determine the phonetic spelling of a word. Currently, this is a hot topic in data science, and it’s a great option for those looking to gain a competitive edge in the job market.

  • Supervised learning – This involves training a machine learning model on labeled data, in order to make predictions about unlabeled data.
  • Unsupervised learning – This involves training a machine learning model on unlabeled data, in order to make predictions about labeled data.
  • Recursive neural networks – These are a type of machine learning model that uses a recursive process to learn from data.
  • Deep learning – This is a subfield of machine learning that involves using deep neural networks to train machine learning models.
  • Regression: Predict future values based on past data.
  • Classification: Determine the category of data.
  • Clustering: Groups data objects together based on some similarity measure.
  • Time-series: This process analyzes data over time.

6. Data Visualization

Data Analysts

Data visualization is the process of transforming raw data into visual representations. This can include pie charts, bar charts, and line graphs, but it can also involve creating interactive visualizations that allow users to interact with the data themselves.

For example, you can put together interactive dashboards using tools like Tableau, and they’re a powerful way to communicate complex data.

  • Spatial data – The key to spatial data is its underlying locations. GIS software and visualizations may involve the representation of points, lines, or polygons as vectors or gridded raster data.
  • Interactive visualization: This specialization involves creating graphics that enable users to interact with data in a meaningful way. Interactive visualization can be used to explore data in ways that are easy to understand and navigate, as well as to generate new insights.
  • User experience design: One of the key responsibilities of user experience design is to create designs that are easy to use and navigate. This involves understanding the needs of your target audience and designing interfaces that are both visually appealing and intuitive.
