Week 4 Forum: Continuous Random Variables /
Continuous Random Variables in Real Life
Continuous Random
Variables in Real Life
Last week we focused on
discrete random variables, and this week we will do the same thing for
continuous random variables. The difference is simple. A discrete random
variable can take on only discrete values (if numeric these would be whole
numbers; if alphanumeric they can be words, names, etc.). On the other hand, a
continuous random variable can take on any numeric value with no restrictions.
Continuous random variables are found in such real world applications as
figuring out the expected lifetimes of manufactured parts, evaluating
standardized college and graduate school entrance exams like SAT, PSAT, GMAT,
etc., and predicting the behavior of populations which are normally distributed
for some variable (e.g., travel times, grades, genetic anomalies, etc.).
This week let’s talk
about continuous random variables and how they are used in business, science
and/or the military. What are some typical real world situations where you find
continuous random variables being used? Pick one such situation and describe it
in some detail. What was the most interesting thing you learned about how
continuous random variables are being used?
Please try, if
possible, to pick a situation to discuss that nobody else has explored in depth
yet. Put the application you chose to explore in the subject line heading of
your initial post (for example, “Continuous random variables used to predict
airport wait times”).
Our textbook does not
have any separate section devoted to real world applications, but you can
peruse the chapter – and especially the problems at the end of the chapter –
for ideas of how continuous random variables are utilized. Another excellent
source of information is the internet. When you search online, some good
websites to try are (but don’t limit yourself to these, there are many other
websites you can use):
and
Be sure to include the source(s)
you use in your post.
Instructions: Your
initial post should be at least 250 words. In addition, please respond to at
least 2 other students. Your responses should help develop discussion around
the topic/feedback that your classmate presented. Responses to students should
be a minimum of 100 words each.
