What is a Data Scientist?
The insights found by a data scientist help more mature companies make decisions about the business, often in the realm of personalization. The primary difference between data scientists and product analysts is that data scientists use code to access and manipulate their datasets, whereas often product analytics requires significantly less technical knowledge.
Similar to product analysts, data scientists also use their skills to put together “data stories,” which include recommendations for changes their team could make to show positive impacts to website or application performance. Often this is by observing cohorts of users and their various engagements with the product to personalize for similar behaviors.
Data scientists complete less measurement strategy than product analysts, but make up for the difference in time with more detailed recommendations for users.
What does a Data Scientist do?
Data scientists spend a bulk of their day writing scripts to combine datasets to find trends or themes that the business can use to improve experiences. They also run scripts, pull complex datasets, and present their findings for teammates to build personalized experiences.
Often companies who employ data scientists have their data housed in complex ways, so to find relationships between sets is a meaty task.
Do I need a degree to be a Data Scientist?
While this role seems more technical, data scientists can come from all backgrounds.
Job descriptions will often mention a requirement of something STEM related, but often bootcamp graduates and product analysts are best off. This is also a popular bootcamp role.

Key Traits & Competencies of a Successful Data Scientist
Quantitative research methods can be learned through classes. Gathering data and presenting it is incredibly important for product analysts.
Data scientists need to deeply understand statistical methods to be confident in the trends and themes they're identifying.
This goes hand in hand with quantitative research. You have to pull the data from somewhere! We'll cover this in tools.
Data scientists have to be able to craft a compelling story with their data. They have to tell the when/what/where/how about the users on their site.
Data scientists are expected to know at least one programming language (SQL, R, Python) and need to deeply understand statistical methods to identify trends.
Data scientists need to know the best methods for communicating data stories via charts, graphs and tables.
As a Data Scientists, you'll work most with:
Difference between Data Analysts & Data Scientists
Analytics is often associated with coding, including SQL or Python to access huge swaths of data stored in warehouses. However, this is incredibly company dependent, and often product analysts are not required to code.
Most popular web analytics tools -- Google & Adobe Analytics, Amplitude, Heap and others do not require programming to access data and have an intuitive user interfaces. If a company is requiring "coding" or "programming," it may be worthwhile to ask about the reason in an interview. If they have lots of data only accessible by warehouse & code, this may be more of a data scientist role!
The main distinction between product analytics and data science is the ability to code-- and data scientists are paid better for it. Don't be fooled into doing data science for lower pay!
