9.2 Paper aircraft confidence interval indoors

This term rain bands were crossing campus which usually cancels the exercise where the students throw paper aircraft from the balcony. This would be the first term to try the new "physical science facility" across from room A101.   In that exercise the long term average flight distance is 560 cm.


Arthisha throws her paper airplane 

With no pre-existing population mean, three aircraft were thrown ahead of class with an average flight distance of 326 cm.


This was put on the board ahead of class. 

Zero cm was the front edge of the mat. Tiles are 60 cm square.

Maryam viewing a video on how to make a paper aircraft, Lidy-Loreen makes her aircraft, Aliha in the background. This is the cell phone generation: they do not know how to make paper airplanes and rely on YouTube videos for instruction.

Planes in the hallway. Measurements were done as planes were thrown.

LanaSunshine throws her plane. Students were told to remain quiet so as not to disturb classes, and to come in to throw and then to step back out.

Marie-Jane on the launching line. One aircraft can be barely seen in the back left corner, the plane flipped and crashed at -51 cm behind the front of the mat.

The spreadsheet was rebuilt for this exercise. The Smartboard behaves better with smaller file sizes. Single tab spreadsheets put less demand on the limited memory capacity. Multi-tab workbooks are clearly problematic. This will have to be the approach moving forward. Single sheet workbooks for current term data, data transferred post-hoc to multiterm workbooks.

Plotting polar coordinates in Desmos and a vector addition demonstrator

Image
In an earlier post I noted that Desmos did not directly plot polar coordinates. Not only was I incorrect, but Desmos responded to my blog to correct me! Although I had at some point seen that one could define a function f(x)=3x+5 and then have Desmos calculate f(6), I had not absorbed how this might be used to plot polar coordinates. The above works beautifully . Realizing that I could effectively program Desmos, I applied this thinking to demonstrating how to add two vectors when given the magnitudes m and the direction angles theta. The graph calculates the i and j components for the two vectors and then adds the vectors, graphically displaying the result while also providing information on the magnitude and direction of the vector sum. m1 and theta1 are the magnitude and direction angle for one of the two vectors, m2 and theta2 are the magnitude and direction for the other vector. All four are dynamically interactive and can be changed. The diagram purports to illustra...

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, o...

Setting up a boxplot chart in Google Sheets with multiple boxplots on a single chart

Image
The  Google Statistics  add-on for Google Sheets can display multiple boxplots in a single chart. The key is the layout of the data. One column should be the variable by which the data is to be grouped, the other column should be the data to be box plotted. Set up the Statistics add-on with the data to be plotted as the variable, and the grouping column as the "by" variable. In this image I had deselected all but the boxplot option, the result was the appearance of the Moment, Standard errors, and Confidence intervals options. The default is apparently a 95% confidence interval for the mean. The result is multiple boxplots on a single chart with a common scale. The new tab that is created also quotes 95% confidence intervals for the mean. Note that as of 2018 the Google Statistics add-on cannot be found by search in the add-ons. In addition, as of May 2018 the add-on no longer verifies, possibly due to the add-on not having been updated since August 2017. One may ha...
