Hello hemangi!!!
Goal Orientation:
The sampling design should be based on the study's goals and objectiv
es .
The picture describe the goal of the research which is achived with the help of objectives, the objectives are the way towards goal. The research should be goal oriented for for achiving that goal the proper objectives must be created.
Measurability :
The sampling design provides the data necessary for analysis . It helps in tabulation of data and to measure the variation in the sample statistically to provide a better handle in determining characteristics of the population at large. It is to understand the probability of sample selection; and to reduce unmeasur
able biases through better sample design. According to that picture the person is measuring some thing with the help of tool , it shows that for doing measurment in the research some tool is must, that may be questionair , interview , observation etc. The measurment criteria is used in such way that the result should be access easily.
Practicality :
Practicality is to translating the theoretical selections into instruc
tions for field works.
In other words, "the most theoretically perfect sample selection procedure is worthless if the field instructions are not "simple, clear, practical and complete." means being able to adapt to whatever irregularities occur during the conduct of the survey.The field work is an important part for doing research. The research should be practical in the sense can be easily conducted on human beings.

Economy :
Research objectives are depend on available resources (time, money, etc.).
It refers to the cost- effectiveness of the survey infulfilling th
e research objectives concerning the fulfillment of survey objectives with minimum cost and effort and maximum output. The picture tells us about how much money the research is needed, how much time the research will take and how much the effort the researcher have to do for this research means the effort is worth for that research or not. The research should be done by considering all the expenses such as money , time means the research should not be time taking and also not very difficult for the researcher.

I understand your situation with no internet in the hostel; I appreciate your efforts to respond to the posts.
I like the way you used an analogy of the tool in the picture with the research tools. But I think here the tools aspect will reflect in the Goal orientation (this will reflect in my thoughts about criteria of sampling design in the next post).
Tools help us collect data, they do not have direct effect on sample, but sample may affect data collection through the tools, for eg: a questionnaire will not affect sample of students, rather how the students answering the questionnaire will affect the data collection hence the tools here don’t bring about any change.
What you’re talking about is measuring the data or criteria with a tool say opinionaire, but what measurability means w.r.t sampling design is that the sample should be measured such that the results should be applicable to the population.
You may get doubts over this but I think they may be cleared once I put up a post in response to the criteria of sampling design.
And I did not quite understand the line “It helps in tabulation of data and to measure the variation in the sample statistically to provide a better handle in determining characteristics of the population at large.” From the measurability bullet, could you explain it in simpler words for me to understand? (It is ok even if you write it in the comments itself as a reply to this comment)
I like the statement used in practicality which is as follows:
“Practicality is to translating the theoretical selections into instructions for field works.”
Could you tell me though how you relate the picture you put up with practicality? Because I had a hard time finding a picture that could convey practicality.
You have covered almost all aspects of economy.
I like the way you have used pictures for each of the criteria. Makes your post look more communicative.
