The thatching exercise this term started off under cloudy and cool skies. Shortly after class began, a curtain of water approached rapidly from the east. The photos were as much a form of attendance taking as documentation of the activity. Lavonna, Lefreeancy, Leeron Henry and Rayden Nemely sorts out her thread Keona Rodrigo Nette, Rosalyn, Tedrick Yoma Rodman Conditions were ideal in the parking lot: cloudy and not hot Then the rain arrived. Note that the razorback ridge to the east is completely gone Initially the class attempted to shelter under the overhang of the top roof The wind, rain, and amount of water coming down forced the class around the corner Rayden, Jayme at a more sheltered location Myra sets up to make doakoahs en ruhk while Lefreeancy works with a rau from lirau   Rayden assisting Jayme Keona and Ian Rosalyn at the edge of a flood from a roof pipe on the right Melissa, Keo...

An attempt to use favorite numbers to generate samples and populations to demonstrate 95% confidence intervals led, inevitably, to failure to capture the population mean. In the 8:00 class I attempted to generate the data wholly internal to the section. I distributed thirteen pieces of paper, three of which were pink. I attempted to use the pink sheets to capture the population mean for all 13 favorite numbers. This worked, but only because at a sample size of 3 the t-critical for a two-tailed 95% confidence interval is 4.3. This only really proved that with a small enough sample size anything can be proven to be true. The confidence interval ran from -4 to 31, a range that will certainly capture the mean favorite number unless a clever student drops a statistical bomb such as a favorite number of a few million and change. And that is the difficulty with favorite numbers - they include high outliers. At 9:00, to end run the problem of sample sizes less than five I used the...

The use of the Google Drive Assignments app in Schoology Enterprise provides a far more interactive student-instructor experience to assignments. Although the following example is from Google Sheets being used in a statistics class, this same capability is available in Google Docs and Google Slides. Using the Google Drive Assignments app allows the instructor to make comments directly in the submitted document. In this instance the comment reflects the use of an incorrect formula. When a student either responds to a comment or clicks on "Resolve" to indicate the the comment has been acted upon, the instructor immediately receives a note in their Updates section of Gmail. This also provides a silent notification on an Android smartphone. Updates do not cause the phone to "chime" as would mail arriving in the inbox. In this regard the Google ecosystem is intelligently designed. With the Google Sheets app preloaded on the smartphone, selecting the ...

Although weather fall 2016 moved the paper aircraft exercise to the Monday after probability wrapped up, weather spring 2018 including passing rain showers and wind inveighed against repeating this sequence. This will return the beads to the schedule and push paper aircraft back to be used either to demonstrate that the distribution of the sample means is narrower than the distribution of the data or used as a vehicle to demonstrate how a sample can be used to construct an interval for which a 95% probability exists that the population mean is captured by the interval. The data currently includes 28 samples from 28 sections of MS 150 Statistics dating back to spring 2012. The result is that the data can be effectively used to show the narrower "taller" distribution of sample means or whether a sample can capture the population mean. There are issues with the data, the most significant being that wind can have a significant effect on the sample mean. The planes perform r...
