Hello, everyone! Today, we’re diving into the fascinating world of averages and what it means to be “average.” You might have heard the term “Average Joe,” which has been around since the 1800s to describe an ordinary person. But in reality, being average is more complex than just a name or a label.
According to demographic studies, the most average person in the world is a right-handed 28-year-old Han Chinese man who speaks Mandarin. He doesn’t own a car or have a bank account, and he earns less than $12,000 a year. However, this doesn’t mean that everyone fits this description. Averages can sometimes be misleading. For example, a study from the 1980s showed that 93% of Americans thought they were better drivers than the average person, which is statistically impossible!
Averages are everywhere, from the design of our homes and shoes to the cars we drive. These designs often rely on average measurements to fit most people. But what exactly do we mean by “average”? The dictionary defines it as a single value that sums up a set of unequal values.
There are several ways to calculate averages, known as measures of central tendency. These include the mean, median, and mode. Each method can give different results based on the data. For instance, when calculating average income, extremely high incomes, like those of billionaires, can skew the results.
To find the most average thing in the universe, we need to look at the smallest and largest measurable entities. The smallest is a quark, about (10^{-18}) meters in size. The largest known star is UY Scuti, with a diameter of roughly (2.4 times 10^{12}) meters. By calculating the geometric mean of these two measurements, we find that the average size is about one millimeter, which is the size of a tardigrade. So, in terms of size, tardigrades are the most average organisms in the universe!
Averages can also vary based on frequency. While there’s only one UY Scuti, there are countless quarks. Therefore, if we consider the mode, or the most frequent value, quarks would be the most common.
Ultimately, averages give us different perspectives depending on how we calculate them. It’s important to remember that being average is subjective and can change based on individual viewpoints and contexts.

Gather a list of your classmates’ heights and calculate the mean, median, and mode. Discuss how each measure of average gives a different perspective on the data. Consider how outliers might affect the mean and how the median might provide a more accurate representation of the “average” height in your class.
Imagine you are designing a new product, like a chair or a shoe, that needs to fit the “average” person. Use average measurements from your class or online data to create a design. Discuss how using averages might help or hinder the product’s usability for different people.
Research the concept of the geometric mean and how it was used to find the “most average” size in the universe. Create a poster or presentation explaining this concept and how it applies to the size of tardigrades. Share your findings with the class.
Hold a class debate on the idea of the “most average person” as described in the article. Discuss the implications of labeling someone as average and how cultural, economic, and social factors can influence this perception. Consider how averages might be misleading in representing individuals.
Create a survey to find out how many of your classmates consider themselves above average in a specific skill, like sports or academics. Analyze the results and discuss how this relates to the concept of averages and the common misconception that most people are above average.

Hello, everyone. Today, we will explore the concept of averages and what it means to be “average.” The term “Average Joe” has been used since the 1800s to describe an ordinary person, but the reality is that names and identities can be more complex.
Demographic studies indicate that the most average person is a right-handed 28-year-old Han Chinese man who speaks Mandarin, does not own a car or bank account, and earns less than $12,000 annually. However, averages can be misleading. For example, a study from the 1980s found that 93% of Americans believed they were safer drivers than the average, which is statistically impossible.
Averages are present in many aspects of our lives, such as in the design of houses, shoes, and cars, which are often based on average measurements. To understand averages better, we need to clarify what we mean by “average.” The dictionary defines average as a single value that summarizes a set of unequal values.
There are different ways to measure averages, known as central tendency, which include mean, median, and mode. Each method can yield different results depending on the data set. For instance, calculating average income can be skewed by extremely high incomes, such as those of billionaires.
To find the most average thing in the universe, we need to determine the smallest and largest measurable entities. The smallest measurable unit is a quark, approximately (10^{-18}) meters in size. The largest known star is UY Scuti, with a diameter of about (2.4 times 10^{12}) meters.
By calculating the geometric mean of these two measurements, we find that the average size is about one millimeter, which corresponds to the size of a tardigrade. Thus, in terms of size, tardigrades can be considered the most average organisms in the universe.
However, averages can vary based on different criteria, such as frequency. For example, while there is only one UY Scuti, there are an immense number of quarks. Therefore, the mode, or most frequent value, would be quarks.
Ultimately, averages provide different perspectives and insights depending on how they are calculated. It is important to recognize that being average is subjective and can vary based on individual perspectives and contexts.

This version focuses on the main ideas and concepts without personal anecdotes or informal language.
Averages – Values that represent the central or typical value in a set of data, often calculated as mean, median, or mode. – In our math class, we learned how to calculate different types of averages to summarize data sets.
Average – A single value representing the sum of a set of values divided by the number of values, also known as the mean. – To find the average score of the test, add all the scores together and divide by the number of students.
Mean – The sum of a set of numbers divided by the number of elements in the set, commonly referred to as the average. – The mean of the numbers 4, 8, and 12 is 8.
Median – The middle value in a list of numbers arranged in ascending or descending order. – When the test scores were arranged in order, the median score was 75.
Mode – The value that appears most frequently in a data set. – In the data set 3, 4, 4, 5, 6, the mode is 4 because it appears most often.
Measurements – Quantitative data obtained by measuring objects or events. – The measurements of the angles in a triangle always add up to 180 degrees.
Frequency – The number of times a particular value appears in a data set. – In the survey, the frequency of students who preferred math over science was higher than expected.
Data – Information collected for analysis or used to reason or make decisions. – The data from the experiment showed a clear trend in temperature changes over time.
Subjective – Based on personal opinions, interpretations, points of view, emotions, and judgment. – Unlike objective measurements, subjective opinions can vary greatly between individuals.
Tendency – An inclination towards a particular characteristic or type of behavior. – The tendency of the data to increase over time suggests a positive trend.
