A quantitative variable is called a discrete variable if its possible values consist of breaks between successive values. When you are finished viewing curriculum units on this website, please take a few minutes to provide feedback and help us understand how these units, which were created by public school teachers, are useful to others. Otherwise the variable is called an infinite variable. I would have preferred something more rigorously mathematical, but beggars can't be choosers, and the book is as its title proclaims an elementary intro to stats, not an indepth treatment. A Sample is a collection of sampling units selected from the population.
Although the author gets a bit too wordy at points create a frequency based on the midpoints of the blah, blah, blahs We all see on TV how political pundits justify opposing points of view by presenting statistics from respectable sources. Those days are gone, and statistics is not likened to astrology any more! How long will the file be downloaded? How could something be a science when it justifies two opposing points of view? In she ran her first marathon to raise money for the AmericanStroke Association.
So, the variables X, Z, and T above are quantitative variables, while Y is not. He wanted his text to be flexible, allowing instructors to teach in ways that would most benefit their students. Though I had a BS in physics, I had never taken a stats class and really felt the lack, so I decided to work through this book. Mario F. A variable is a rule or a formula or a mechanism that associates a value with each member of the population.

Though I had a BS in physics, I had never taken a stats class and really felt the lack, so I decided to work through this book. A different way to understand a discrete variable is that the possible values of the variable can be written down or can be counted in a finite or infinite list.
The quality of the book is awesome! Many of his texts, such as the tenth edition of his calculus text, are leaders in their markets.
T assumes only integer values and is therefore not a continuous variable. At that time he accepted a position with Penn State University, and he currently holds the rank of professor of mathematics at the university.
I will definitely be ordering from them again. Next, the unit will define and compute measures of central tendency including the mean, median and mode of a set of numbers. Roughly, this means that if he makes the same prediction one hundred times he will be correct 95 times, and it will not rain the other 5 days.
The problem is that sometimes a weatherman will hide the information that there is a 95 percent chance only. My take away is to still hate and distrust statistics and statisticians.
Essentially, parameters are unknown and the main game of statistics is to try to estimate parameters on the basis of small samples collected from the population. Whitney Zimmerman is the author of these course materials and has taught this course for many semesters online.
Out of sight and mind, I do not need reminders. We are mostly concerned with numerical data i. The answer is that statistics has a scientific basis but it can be misrepresented in use. Suppose we are studying the KU student population.
There are several basic objectives for this unit of study. Triola is a Professor Emeritus of Mathematics at Dutchess Community College, where he has taught statistics for over 30 years. Online Notes About Statistics is the art and science of using sample data to make generalizations about populations.
