A
relationship maps out correlating elements from one set to another set. The article found on the Wall Street journal "For Investors in Retail, Shopping Spree is Over," explains how Target recently experienced a sophisticated security breach that stole
vital and personal (credit card) information from over 40 millions customers.
The relationship between season shopping and the security breach
had a positive (direct) relationship. Moreover, retail stores beyond Target, also
experienced a decline in sales. The function isn’t linear because there isn’t
a constant R.O.C between the security breach and the amount of Target (retail)
shoppers. This example is a mathematical model because the outputs (amount of
shoppers) depend on the input (security breach). The article "Working Hard or Hardly Working" found on The Economist, explains how the employment rates weren’t as high as economist projected them to be. This is not a
function because there are multiple possible “inputs” for the output of “unemployment”.
I also chose the economist article "Working Hard or Hardly Working", but I used it as an example of a function. I thought the only input is time as given in months but I might be wrong. Interested to hear your opinion.
ReplyDeletesam, you are correct. the second article is an example of a function.
Deleteyasimine,
ReplyDeleteyour first example is explained in good detail and it sounds like it was an interesting article. next time include the url of the article so that i can better assess whether your explanation matches your example.
for your second example, i know that the relationship is a function because a few other students used this example. it is not the correct example for a non-function.
