First of all let me tell you all what a great job you did on Saturday!! It was worth the wait.. :) And I, in particular, was very happy..!
Ask me why, Cause I saw Gauri and Sneha doing sampling!..right there while they were drawing out chits for the 1 minute games!! :)
We were a population of girls from MET CA - 4 and MET CA - 5 (Whose chits were made) and a selected number of girls (the sample in this case) were required for each 1 min game,
so you resorted to the most basic form of sampling giving every girl a chance of being selected for the games!
But here the sample or the selected individuals were easily available, that is we were right in front of you and had no problems with being associated with the games..but what if this was not the case?
This is when we come to the topic of Accessibility of a sample..... on Friday we talked about Concept of population and sample and on Saturday we discussed what is representativeness of the sample.
As we had discussed, representativeness of a sample is important but so is the accessibility issue related to it. Simply it means that after theoretically looking at the sample i.e. deriving the 'number' of participants in the sample is one thing and actually 'meeting or accessing' the sample is another.
Sometimes this issue may be related to permissions that must be sought from authorities. For e.g. while working with young school students, it is important to take permission from their teachers as well as parents.
But just taking permission is not enough. Accessing the participants should be practicable too.
For e.g. if a researcher wants to find out the effect of busy schedules on the academic achievement of child artistes working in popular serials or movies, then the researcher may get permission, but may not be able to meet the participants as they would be too busy!!
This is just one type of problem in access of a sample, Louis Cohen and Lawrence Manion have written about other such problems about accessibility in their book :Research methods in Education (you may also look for the print copy of this book in our Juhu library).
Meanwhile you can take a look at the online version of this book.
Instructions:
- After going to the following url, you will be directed to a page were you will see the cover of the book in the top left corner
- Below the cover, there is a "preview this book" tab, click on it and you will be directed to the contents of the book.
- After this, you put in the search term "access" in the "search this book" option to your right, many pages will be displayed with the Page nos. click on "more" in that list.
- You need to look at page 98 and page 99
- You may need to sign in with your Google account for you to access the contents of these pages,
After going through through this post and Louis Cohen's online reference, I'm sure you all can think of at least 3 examples that a researcher might face in accessing a sample, I request you all to put up your answers (on your respective blogs as posts) before 8 pm. so that we can proceed at a decent pace. See you in the evening~!
