Statistics Workshop by "Professor" Christina

Last week, when Paulo brought us to his class of third/fourth-year English students, Mackenzie and I learned that students are required to do a quantitative analytical paper and defend it but have never been taught statistics or research methods. Many of the students seemed lost and stressed out about having no experience in data collection and analysis. So, as the resident economics major who just finished a course in Econometrics, I offered to do a "statistics workshop" and help them formulate their analysis plan for their research topics.

The following Monday (this Monday), it went well: students who had no experience with what we, Americans, claim to be "basic" graphs like y=mx+b left the session with an understanding of qualitative versus quantitative data; different types of data; descriptive statistics, regression and ANOVA; and even graph and table options for visualization. I'm really glad I could help them out and it felt great when many came up afterward to thank me. (I got a kick out of one student who continued to call me "Professor.") Even, Paulo and Mackenzie were pleased and took notes. Without going too much into the calculus, I was able to share what I had learned and show each principle conceptually and technically - and helped them set-up Excel's automatic analytics tool. Watch the presentation below!

Hackathon: TechTogether Boston

Image
iOS app Last weekend, I had the wonderful opportunity to participate in Boston's largest all-female and non-binary hackathon! A group of friends and I wanted to digest as much tech and nerd information as possible, and we basically made it our mission to go to nearly every workshop session offered for two days straight. I don't know how we managed this but we did. From 5p on Friday and all day on Saturday, it seemed I bounced from one room to the next with a nap here and there. There was a workshop on rapid prototyping with AdobeXD -- which I am in love with. Then, I was able to create my first phone application during a workshop on iOS app development with Swift  (it's much easier than I had imagined), followed by a workshop at 2am on Android app developmen t. For my very first hackathon-conference, I wanted to focus on skill development and learning, rather than the competition. However, seeing everyone so wrapped up in their individual designs and programming ...

Women of Color in Graduate School

Image
Recently, I've been asked (by a few people) how it feels to go through graduate school as a woman of color. And, to be completely honest, it's incredibly exciting and exhausting all at the same time. Being a woman of color -- specifically a black woman, particularly in STEM -- has a lot of challenges. If you simply search the phrase "black in graduate school," you will get statistics that are very humbling; articles and think-pieces on how different the Black or person-of-color experience is from students who are not minorities; and other outlets detailing how little support many Black and non-Black students of color feel that they have. In fact, the Council on Graduate Schools recently reported that, in 2017, Black students made up just 11.9% of all first-time graduate students in the United States. (That said, 68% of them were women! So, we are making p r o g r e s s.) I'm not sure what the numbers are at Boston University, but it doesn't seem that far o...

Truss Design (Final)

Image
We finally made it to the end! After the preliminary design report, it was time to finalize our actual design (since we were given enough materials to make one truss to test). After doing a few more draft sketches and analysis, I was able to pick up on patterns on which types of designs produced the maximum strength (all within the parameters we were given). Finally, I came up with the sketch at the bottom-right, and the MATLAB analysis produced the highest load we were able to reach. We theorized that: two members would buckle first instead of just one (Members 3 and 4); the maximum load is 11.62 ± 0.063N; and the total cost of the truss is $290 (under the budget limit). From there, we moved to prototyping: we cut the straws as close as possible to the lengths specified in our final design. To create uniform gusset plates, our "joints," we used the circular cap of an individual Tropicana Orange Juice bottle. It met the area requirements and acted as a stamp...
