Both do involve collecting and analyzing data, usually to make decisions in a business context, but their differences are numerous, and it’s important to know the differences between the two if you’re considering a career in either.
In this article, we’ll explore those differences. By the end of this article, you won’t just know the differences between the two. You’ll also be able to make an informed decision about which career path is right for you.
Is There a Difference Between Data Science and Statistics?
Yes, there is a difference between data science and statistics. In general, statistics is the study of numerical or quantitative data to make predictions or draw conclusions about a population. Data science is an applied subset of statistics that uses statistical methods to analyze large amounts of data and understand the results better.
Data Science vs. Statistics: Discipline
Data science and statistics are two closely related fields that do overlap. But they are also distinct in some ways. Here’s what makes each discipline unique.
What Is Data Science?
Data science is the process of extracting knowledge from data in various forms. It involves data cleaning, integration, visualization, and statistical analysis of data sets to uncover patterns and trends. Data scientists use tools such as Python, R, SAS, and Tableau to analyze large amounts of data.
What Is Statistics?
Statistics is a branch of mathematics that deals with collecting, analyzing, and interpreting numerical data. It can be used to help identify patterns in data, determine whether there are any significant differences between two or more data groups, and make predictions about future outcomes based on current trends.
Data Science vs. Statistics: Applications
Let’s look at the different applications of data science and statistics to determine which career would suit you best.
What Are the Different Applications of Data Science?
Computer programming is one of the most common applications for data science. This allows for the creation of programs to make decisions and solve problems. A program could be designed to analyze your search history and suggest products based on your interests or needs. Another way is to create artificial AI bots that can talk to people online or perform tasks.
Another application for data science is in marketing strategies. Companies use data from past experiences to predict what customers might want next and plan accordingly, so they can offer those items before any competitors do. This strategy has helped many companies succeed in their industry because they’re able to provide precisely what their customers want without second guessing.
Data scientists also work closely with engineers who design new products; together, they figure out how best to use technology within those products, so they perform better overall than if those same technologies were used separately.
What Are the Different Applications of Statistics?
Statistics are the backbone of many industries, including the scientific community, business, and government. Statistics can be used in everything from determining how many people will attend an event to determining whether or not a product is healthy or safe.
Statistics are also used to interpret data from experiments and surveys.
Data Science vs. Statistics: Process
The data science process is much more complex than the statistical process. It involves several steps, each requiring significant time and effort.
What Does the Data Science Process Look Like?
The first step in the data science process is collecting data from various sources. The next step is cleaning the data, removing irrelevant information, and combining different datasets.
Then comes analysis and interpretation, where statistical techniques are applied to the datasets to find patterns or trends that can be used for decision-making.
Finally, there’s visualization, where graphs or charts are generated based on the data analysis results so that people can easily interpret them.
What Does the Statistical Process Look Like?
On the other hand, the statistical process starts by collecting the data through surveys, questionnaires, and interviews. This data is then analyzed and tested for statistical significance.
After this phase is complete, it’s time to create hypotheses that can be tested on the population of interest. The next step is to design an analysis plan that will allow you to test your hypothesis as thoroughly as possible. Finally, you’ll run your experiment and analyze the results before deciding whether or not your theory is true.
Data Science vs. Statistics: Type of Data
Both statistics and data science are used to analyze and interpret data. But the two disciplines have some distinct differences in terms of which types of data professionals use.
What Type of Data Do Data Scientists Usually Use?
Data scientists often work with unstructured data, which does not fit into a traditional database structure. It can be thought of as “free-form” data or data with no apparent structure. Unstructured data can include emails, documents, images, audio and video files, social media posts, etc.
What Type of Data Do Statisticians Usually Use?
Statisticians use two main types of data—categorical and numerical.
Categorical data include things like gender, race, or political party affiliation. They are often coded as numbers, but they can also be represented by letters or other symbols. This data can be further classified into nominal and ordinal data.
Numerical data are measurements such as age or height. They often appear in charts that look like tables of numbers. This data can be further classified into interval and ratio data.
Data Science vs. Statistics: Tools
Here are the tools that data scientists and statisticians use to do their work.
Popular Data Science Tools
The most popular tools data scientists use are SAS, Tableau, and Python.
SAS is used by companies that want to analyze large amounts of data, while Tableau is used by smaller businesses that need to visualize their data and make it more accessible. Python is another popular tool because it is used for machine learning and artificial intelligence applications.
Data scientists also use TensorFlow, an open-source library for machine learning models.
Popular Statistics Tools
SPSS is a popular statistical software tool used by statisticians. It’s a program that uses statistical and mathematical procedures to analyze data. It’s used in research, market analysis, and other applications.
Additionally, statisticians use Microsoft Excel for graphs, charts, and tables and MATLAB to analyze their data.
Data Science vs. Statistics: Career
Data science and statistics are both highly sought-after skills in the modern workplace, but the two roles are often quite different in terms of the work they involve.
What Does a Data Scientist Do?
A data scientist is an analytical professional who uses qualitative and quantitative methods to solve business problems. They use their expertise to collect, analyze, and interpret data to help their organizations better understand their customers.
