Question

true/false please fast I'm taking a test

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 that凶all 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

Answer 1

1). Sampling is always wrong because it is stupid trying studying 300 million people with a sample of 1500 -----> FALSE (the results obtained by the random sampling of a specific number of people from population represent the whole population that are living under same environmental conditions).

2). Probability samples are the same as accidental samples. ------> FALSE (accidental sampling (or convenience sampling) is a type of non-probability sampling).
