May 22, 2017 -- SienaSemanticsSurvey -- Code Breakdown -- Cell #6 & #7


Cell #6:
Some of the questions asked students to rank from 1-7, where 1 would be least positive, and 7 the most positive. Therefore, the code sets up that if a particular question is known to be in the reverse order where 1 corresponded to the most positive, the python code will automatically switch a 1 to a 7, switching a 2 to a 6, 3 to a 5, a 4 will remain a 4, and so on, just replacing the values with their opposites in the bounds of 1-7. The questions that were in the correct order from the first sentence, are left untouched, only the flipped ones are adjusted.

iloc --> works on positions in the data (integer locations only)

Cell #7

Going through each year's survey to find the specific questions that have flipped ranking from 1-7, then finding the corresponding column in the excel data for the survey to identify the columns that need to undergo the python code that will reverse the values to become 1 to 7, 2 to 6, etc. The columns that correspond to these specific flipped questions are listed under the corresponding vectorS14/15/16/17 depending on what year the data was gathered from.

SemanticsS17.iloc[0:9,4:19] --> creates a chart using a sample of data from '17 for the first ten rows (the first being the titles of the columns) and 9 students responses, and the 4th-16th columns and responses.

6/14/17 Notes

I want to write a code so that I can search the name of a class, and everyone who took that class will appear. Originally I assumed I could use the same command I did to search for a specific name, and then edit that so the code would search for a specific person. However, looking at the format of the file, there are four different columns that contain class information, while there’s only one column with name information. I am going to see if I can search for a specific class in the “Am S1” column first to see if everything runs smoothly, and if that works, I will look for ways to search for an ID word in multiple columns. I tried this command. Only the column headings are appearing and nothing else Studentinfo14[Studentinfo14['Am S1'].str.contains('Discovery', na=False)] I changed “Studentinfo14” to attendance so that the code would look for this information in the attendance file instead of the master file. This worked, but using this file means that I ca...

6/06/17 Notes (formatting code and searching for a specific person)

Working on fixing the format of the code, deleting cells, and making sure everything in an organized order to make it easier to use Earlier I was having a problem displaying the Confidence survey chart so I renamed all the columns and then it displayed. I now found that the command “ConfidenceS#.lock[:,:] also works, and is much more efficient because now I don’t have to go through each survey and copy and past the column names for every year of every survey. This works for all of them except Semantics, not sure why. I finished adding all the survey information I needed to merge all the surveys for 2014. I keep getting errors in the cells that deal with inverting numbered responses because certain column headers “don’t exist.” This means I actually will have to rename all the columns. However, for some reason this does not affect the cells that merge all the data. I successfully uploaded all the files onto the code and merged all the surveys and the attendance spreadsheet to...
