Students in SC/SS 115 Ethnobotany gave presentations on the botany and local names of cyanobacteria, lycophytes, and monilophytes.
Vanessa and Julie Ann present plant names in Kosraean and Pingalapese. Julie Ann noted that the Nephrolepis fern called rehdil in Pohnpeian is actually called neiniko in Pingalapese. Her source for this was Mihner Ioanis, her grandmother.
Jasmine and Jayheart covered the life cycle of ferns with a well done diagram.
The life cycle of ferns diagram was one of the better ones I have seen over the years.
And then everything changed. For the first time since the loss of Gnumeric a spreadsheet was displaying a box and whisker plot. To back up to the beginning, MS 150 Statistics was built around spreadsheets. Students in the course were not statistics majors and the overwhelming majority were not in a scientific field. Most would wind up working on office desktops for which they would not be an administrator. Downloading R would not be an option and R would be steep learning curve for some for whom computers are an unfamiliar technology.
Spreadsheet based statistics, for all the faults and potential for error, would be at the center of the course. The use of Ubuntu in the classroom meant using LibreOffice.org or Gnumeric. Gnumeric provided the capability of including box and whisker plots. A change in computer laboratory technology to Microsoft Windows five years later saw the use of Gnumeric on Windows - until Gnumeric stopped supporting Windows. A further change of my work top to OSX f…
My approach to creating histograms for the past sixteen years has been to have the students determine the minimum, the maximum, calculate the range, divide the range by the number of intended classes to find the width, and calculate the class upper limits. The class upper limits then permit the use of the FREQUENCY function in spreadsheets such as Excel, LibreOffice.org, OpenOffice.org, Google Sheets and Gnumeric. While in Excel and LibreOffice.org the existence of a gap width or spacing setting allows the columns to touch, Google Docs did not provide this option, hence the chart seen below.
