QUESTION 10 Less randomness and more difficulty in obtaining
Solution
Here in this question we have 5 options to the question \"Less randomness and more difficulty in obtaining a sample size are disadvantages of ----\" . The options are :
a. Mail Surveys b. telephone surveys c. personal interview surveys d. social media e. online experimentation
Now when we talk about sample size in surveys , sample size is the number of respondents required for a survey to be effective.
a. Mail surveys : Here questionnaires are sent to a target group of respondents through mails and respondents are expected to respond on those questionnaires . So here there is no randomnous and but not much difficulty in obtaining a sample size.
b.Telephonic surveys : Here again the target group of respondents is contacted through telephone and asked questions against pre set questionnaires . So here there is no randomnous and but not much difficulty in obtaining a sample size.
c. Personal Interview Surveys : Here again the target group of respondents is contacted for personal interviews and asked questions about a preset topic or a preset area of survey. So here there is no randomnous and but not much difficulty in obtaining a sample size.
d. Social Media Surveys : Here surveys are done through sites such as Facebook , Linkedin etc and there is less randomnous but more difficulty in obtaining a sample size as we can not make out how many respondents will respondent will respond as respondents have their own connections in their own network within the sample social media site who may also respond so we really do not know how many respondents will respond.
e. Online experimentation : Here questionnaires are distributed online over the internet and primarily through emails . So here there is more randomnous as we do not know who is responding and whether he or she is the right person . And alsoalthough we can make out to how many respondents the surveys are being sent but how many of these constitute our sample size for our survey or are actually are our respondents we cannot determine . So here there is more randomnous and more difficulty in obtaining the sample size.
Now if we compare all five types of surveys above then may be d. social media should be the right answer.
Now to answer the question let us define each of the above 5 surveys and see what are their disadvantages in terms of determining sample size.
