Pulling a sample

November 9, 2010

I am a few weeks behind on my research, waiting for my methods book ordered from Amazon a month ago to show up. I am doing an Interpretative Phenomenological Analysis, and need to begin work on developing my own experiences in order to bracket them during the research.

271693. That is how many tweets are in the #edchat archive. I am using Research Randomizer to randomly choose 4 of the 52 weeks between September 1, 2009 and september 1, 2010 that I can use to extract my sample. By asking for four random numbers between 1 and 52, I can randomly select 4 weeks of archives.

1 = Tuesday, Sept 1, 2009 to Monday,  September 7, 2009

2= Tuesday, September 8, 2009 to Monday, September 14, 2009

and so on until week 52, which is Tuesday, Aug 24, 2010 to Monday, August 30, 2010.

I chose this period because I wanted a way to somehow acknolwedge the flow of an academic year, and account for things like the traditional summer break of July/August in msot educational settings, or for the intense exam periods in many academic environments. These academic timetable factors may influcen how active or non-active educators are on Twitter. Since there is no way to fully account for these types of flows within all the possibl academic settings these educators are coming from, I decided the best strategy would be to randomly pull 4 weeks from the year and pull a sample from those four weeks.

The random weeks drawn from the randomizer are 47, 43, 28, 33 (screenshot), meanign the 4 weeks I will be pulling my sample from are:

  • Week 28: February 2-8, 2010
  • Week 33: March 9-15, 2010
  • Week 43; May 18 – 24, 2010
  • Week 47: June 15-21, 2010

I am off.
