true/ false
1, Sampling is always wrong because it is stupid trying studying 300 million people with a
sample of 1500 2. Probability samples are the same as accidental samples. 3. The most important
feature of probability sampling is thatall members of the population have an equal chance of
representation 4. Snowball samples accumulate subjects through chains of referrals and are most
commoaly used in qualitative research 5. Stratification is the process of grouping the members of
a population into relatively homogencus strata before sampling 6. Sampling distributions are the
same as frequeney distributions in all material respects. 7. Samples generate parameter estimates
while populations generate statistics 8. The most carefully selected sample is almost never a
perfect representation of the population from which it was gathered. Some degree of sampling
error always exists. All naturally or randomly oocurring empirikal phenomena are normally
distributed. 10. In general, non-probability-sampling methods are not regurded as less reliable
than probability 9. samples. 11. Survey research involves the administration of questionnaires to
a sample of respondents selected from some population 12. Questionnaires may be administered
in four different ways: face-to-face interviews, telephone surveys, mail-surveys, and internet
surveys. 13. Face-to-face interviews are the very best method of survey research in all
circumstances 14. In survey research, response rates are the proportion of the sample that
actually completes the -15. An experiment is a method of scientific inquiry in which an
independent variable is deliberately manipulated in order to observe its effect on the dependent
variable
Solution
1) TRUE that is why we have sampling errors that we take into account in the calculation . Still
some sampling errors are unavoidable.
2)False probability sampling is a sampling technique in which probability of getting a sample is
calculated.
while accidental sampling does not meet this criterion.
3) FALSE in probabilistic sampling all members have equal chance of selection
4) TRUE it is right that snow ball sampling accumulates subject through chain of accumulation
but they are biased because they give people with higher social connection higher chance of
selection. This is non probabilistic sampling and used in qualitative research generally for those
groups which are hidden . These are not accessible to researchers through other methods.
