Do you know what a statistician is? From the word itself, you can determine that it is someone who deals with statistics, but is there more? What are the different layers to the position, and how is it beneficial to our economy and society? In this Guide for Statisticians, you’ll read about what a statistician is, the history of statisticians, and what preparation is needed to pursue a career as one. You will also learn about future trends of statisticians and their current contributions to help eliminate the Covid-19 pandemic.  

What does a statistician do? You can easily think there is not much to it, they just deal with numbers, it is singularly focused, or it is not that important of a position. In fact, it can be argued that almost every human activity involves applying statistics, making it an important component of our daily lives. Therefore, a statistician is highly valued, needed, and an essential asset to society. 

What is a Statistician?

data

To understand what a statistician is, we need first to define statistics. Statistics are everywhere. Merriam-Webster defines it as a branch of mathematics that deals with masses of numerical data from the collection stage through the presentation stage, including analysis and interpretation. It is also “a collection of quantitative data.” You sometimes hear the saying, “statistically speaking,” when someone is attempting to show support for their side of an argument or in an explanation, in general. They say this because statistics deal with facts and data and can be more accurate, believable, and probable than just opinion. But statistics are useless without knowing the proper data collection methods, analyzing it meticulously, interpreting it correctly, and presenting accurate conclusions that lead to effective decisions. All of this is precisely what a statistician does. 

Skillset

Statisticians typically work in an office setting, and commonly work 40 hours a week, with occasional overtime. They are decision-makers who enjoy independent and detail-oriented work, routines, and can manage their time wisely. Some other important abilities include solving huge problems, analytical precision and accuracy, communication skills, reading comprehension, determination, critical thinking, active listening, concentration, and math skills, especially calculus, statistics, and linear algebra. Statisticians need to understand statistical analysis, data modeling, data analysis, and Microsoft Excel, and be able to navigate statistical programming languages like R, SAS(Statistical Analysis System), Python, C++, and SQL (Structured Query Language). People designed this way have the potential to find the statistician job highly satisfying. 

Duties

As stated earlier, statisticians collect, analyze, interpret, and present data. They work hard to obtain an extensive amount of knowledge and skills to perform their duties. Let’s look at the aspects of the job in more detail. 

  • COLLECT: In the collection phase, statisticians are responsible for determining the relevant data needed, creating the proper collection method, and executing it through opinion polls, interviews, experiments, surveys, or reviewing records.  
  • ANALYZE: To analyze the data and identify trends and errors, statisticians will perform validity tests, utilize specialized software, and even develop new models and software. 
  • INTERPRET: From the analyses, statisticians can check for accuracy, efficiency, and define whether the findings are valid and applicable. 
  • PRESENT: Once conclusions are formed, statisticians prepare graphs, tables, bullets, charts, and reports to present to coworkers or clients. 

Types of Employers

Statisticians assist private and public businesses and organizations in making accurate, efficient, and improved decisions that solve real-world problems. Unlike most jobs, statisticians play a crucial role in local, regional, national, and international development through a vast array of fields and industries. John Tukey, a distinguished and renowned statistician, described the best part of working as a statistician is you have the advantage of “playing in everyone’s backyard.”

The five top types of employers for statisticians are government, healthcare, research and development, universities and colleges, and insurance companies. In the realm of government, statisticians work with data dealing with wages, education, unemployment, policy formation, housing, endangered species, drinking water, and populations. In the medical field, statisticians, or biostatisticians, work to discover the origin of outbreaks, test medications, develop drugs and vaccines, keep track of the world health population, track pandemics, like COVID-19, and create studies that help treat sickness and disease. As for research, statisticians conduct experiments and testing on various types of data to help improve the development of all kinds of products, services, and goods. At universities and colleges, statisticians may “identify, research, and resolve unexplained issues” and look into new theories that involve statistics and mathematics.

According to Payscale, popular employers include the U.S. Census Bureau, Public Health Institute, Mayo Clinic Arizona, the University of Michigan, and State Farm Insurance Company. Some of the big tech firms like Facebook, LinkedIn, Google, Twitter, and Microsoft also need statisticians to be a part of their quantitative analysis teams. 

Statisticians also team up with and play a role in engineering, industrial design, chemistry, accounting, economics, state management, business, sports, and public safety. They also impact urban and rural planning, banking, operations, trade, state management, natural and social sciences, social work, and commerce. They use their expertise to impact the environment, supply chain, artificial intelligence, weather forecasting, election predictions, the functions of the internet, and mobile apps. In more detail, statisticians in the business world calculate salaries, profit, and loss, determine the probability of sales, and conduct research regarding products, customer service, and consumer goods. 

Pay

Let us answer an important question on everyone’s mind: how much does a statistician make? PayScale states that the average statistician salary rests over $73,000 a year. U.S. News & World Report, in 2018, reported statisticians brought in an average annual salary ranging from around $67,000 to $113,600. The U.S. Bureau of Labor Statistics reported an annual salary of over $91,000 for statisticians in 2019. Any way you look at it, a statistician is paid very well and has the potential to make six figures. The “best-paying” cities include Raleigh, Boulder, Boston, San Francisco, and Bridgeport, Connecticut, ranging from $111,180 to $142,520. The “highest mean salary states” include Washington, D.C., California, Maryland, Massachusetts, Idaho, and New Jersey, ranging from $104,310 to $116,090.  

What is the history of Statisticians?

Since the need for statisticians appears to be growing in almost every field due to all of our technological, medical, and economic advances, statistics can feel modern and more like a newer career option. The reality is that statistics have been around a long time, even back to ancient times. People have been analyzing and interpreting them well before the terms statistics and statisticians were coined. Let’s take a look at where statistics started, how it has evolved, and the impact statisticians have had throughout the process. 

Certain aspects of statistics, including mean, mode, and sampling, were utilized back in the 400s BC in determining the original date of the Olympics and in war strategy. In AD 2, the Han Dynasty conducted, from what we know, the first Census, and in AD 7, there was a Roman census in Judea. Al-Kindi established frequency analysis to break secret codes in the year 840, and the earliest educational graph, regarding the planets, appeared in the tenth century.

Statisticians in the 1000s – 1600s

Britain’s great Domesday Book was completed sometime between 1069 and 1085 and is Europe’s first official account using statistics. It contains the results of a land survey involving villages, farms, societal order, and livestock ordered by William the Conqueror. There is a Chinese diagram created in 1303 that is the foundation for the “mathematics of probability” and was later named after the 17th-century French mathematician, Blaise Pascal, as Pascal’s Triangle. Statistics were used in 1346 to determine population and trade in Italy. Throughout the 1600s, statistical data graphs, probability theory, statistical mortality tables, and data visualization maps were born.  

Statisticians in the 1700s – 1800s

In the middle of the 1700s, the word ‘statistik,’ German for ‘statistic,’ was established. As we move through the century, conditional probability, hypotheses testing, economic data displayed on bar charts and graphs, and the recording of temperatures and climate changes were first seen. In 1790, the United States experienced its first Census equaling almost four million people. 

Many fundamental statistical concepts and formulas were created and discovered throughout the 1800s by prominent statisticians and mathematicians: 

An incredible breakthrough was seen with the start of medical statistics in tracking disease and epidemics, especially with John Snow’s Cholera Map, where he was able to identify the source. Also, a survey was conducted by Charles Booth to show the level of poverty in different areas of London, and Karl Pearson introduced Standard Deviation.

Nightingale Rose Chart

The famous female statistician, Florence Nightingale, created the first pie chart: the Nightingale Rose, showing war casualties. She joined the Royal Statistical Society, the first woman member, and became the first member of the American Statistical Association who did not live in America. The British Science Association established a section focused on statistics that turned into the  Royal Statistical Society, and the American Statistical Association was also formed during this time. 

Statisticians in the 1900s

Bachelier introduced Financial Mathematics, and William Sealy Gosset created the T-Test through the Guinness brewing process. This century also saw companies merge to form what would become the pioneering IBM company, and R.A. Fisher introduces his Design of Experiments. Regarding Germany, Alan Turing used Bayesian statistics to crack Germany’s Enigma Code, and statisticians predicted an accurate number of tanks that Germany would produce in World War II, creating the German Tank problem

Other important statistical advancements within the 1900s include:
