## About Melissa

Melissa Gardenghi, Chair of the Mathematical Sciences Division, completed a B.S. in Engineering and an M.Ed. in Math Education from Bob Jones University. She then continued on to earn an M.S. and Ph.D. in Mathematical Sciences from Clemson University. In addition to her graduate work, she has passed the Society of Actuaries Exams P and FM and completed the VEE credentials in Applied Statistics and Corporate Finance (see full bio).

### Professional Interests

- helping students improve the effectiveness and efficiency of their learning
- teaching students to apply statistical tools to solve relevant problems

#### Improving Math Study

We will be offering a weekly seminar for math and actuarial students to discuss practical ways to improve mathematical learning (Fridays, 8am). Contact Dr. Gardenghi for more information. I've also given a couple of seminars related to studying mathematics. Resources from those are available on our departmental website.

#### Learning the statistical software R

R is an open-source statistical software package that can be downloaded from https://www.r-project.org/. A more user-friendly interface, RStudio, is available from https://www.rstudio.com/ (be sure to install R first, otherwise RStudio won't run).

Things to remember: R is powerful (and free), but a little hard to learn to use (you have to pay big money for the easier to use interfaces, which are actually less flexible to the advanced user). Persevere, learn to use google effectively, and don't be afraid to try things.

A selection of user manuals is avaliable at https://cran.r-project.org/manuals.html. However, unless you want to work through the manual, I find google to be more efficient in answering my questions. A selection of pdf cheat sheets can be handy and is available at https://www.rstudio.com/resources/cheatsheets/.
