2.2 Quartiles using 116 rows of Vitz data

In the past student heights were used to introduce quartiles. Last term a set of spherical objects were used - which were too few to make the concepts clear. This term 116 Dolihner - Palikir commute times were used. 


The concepts were first illustrated on the board. And then demonstrated in the spreadsheet. Boxplots were produced in Statisty, BoxPlotR, and Desmos on the Smartboard.

Towards the end of class I worked homework 2.1 on a cell phone, mirroring my work to the Smartboard. The Smartboard does not drop the connection as in the past. 

A new behavior was observed this term. As in the past the Google Sheets copy on link did not work on a cell phone. A View only version of the spreadsheet opened. As in the past, the Make a Copy option was attempted. This term Make a Copy failed. The end run was to copy the data in the View only spreadsheet and then paste the data into a new spreadsheet. 

With mirroring functional, a demonstration of how to make a box plot of the 2.1 data was demonstrated.

On a cell phone, with Statisty running a Chrome browser on Android, Statisty will not paste spreadsheet data in as a column. Although the settings allow the setting of a data separator, there does not appear to be an obvious way to paste in a tab character.

Desmos will not permit any paste into the Desmos app on a cell phone.

Even if one attempts to paste from the clipboard, Desmos balks.

The only option that worked on an Android cell phone was BoxPlotR running in Chrome. This reinforced the importance of running live demonstrations in class. That is where what will go wrong, will go wrong.

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...

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...
