Class 14– Oct 9
Excel as a Modeling Tool + Professional Email
today’s plan
•email•math modeling with Excel (PA 14)•creating graphs in Excel•assignments & announcements
email:
love it? hate it?let’s talk about it.
course competency“utilize effective and professional email communication in the course of a project”
you will submit an upcoming competency assignment as an email attachment
let’s characterize attributes of professional email
professional email • proper salutation • closing (who is it from?)• appropriate/useful subject line• proper grammar/spelling (not
texting grammar)• professional tone
more email etiquette • avoid using all caps• consider your signature• cc when necessary (not more)• find other ways to send large
files
modeling with Excel
get out your laptops and open up Excel
“All models are wrong. Some are useful”
- George Box
remember your own dental hygiene process? we now want to build a math model to estimate the annual cost to implement it.
take a few minutes to write out (by hand) the variables and/or equations you will need for this model. work in teams of 2 or 3.
reporting out • what were your variables?• what was your final equation?• what assumptions did your
model make?
one possible model
Ci = cost of tool i ($)Li = longevity of tool i (in days)x = total number of tools
annual cost =
longevity
ui = single usage amount of tool i si = purchase size of tool ini = # of times/day tool i is usedx = total number of tools
Li =
finally
annual cost ($) =
where Li =
Ci=purchase price; ui=single usage amount; ni = number of uses per day, si = purchase size
let’s model it in Excel
individually, you will build the model to predict the annual cost of your dental hygiene process using Excel
some style tips • store values separately from
equation• name cells that store key
equation variables• use colors to identify model
inputs/fixed values
figures – must haves • title• legend (when necessary)• caption (when included in
communication)
ok, here we go…
using the guidelines on the provided handout, build, execute, and then plot results of your team’s models. I’ll be around to help where you need me.
