Descriptive Statistics (Lesson 2/5)

Measuring Center

1 / 11

When given the set ​[1,2,2,5,7], if you are asked for the "typical" value of numbers, what would you say?


Often, people will take the average, or mean, of the numbers:

​
51+2+2+5+7​=517​=3.4.
​

Therefore, you might argue that the numbers are clustered around ​3.4.
