Q1. A research team hope to conduct a quantitative study to examine the social relationship structures among drug users in DTES, which of the following sampling strategies would you suggest them to take? A. Stratified random sampling B. Multi-stage cluster sampling C. Snowball sampling D. Systematic sample E. Quota sampling A X Q2. Which of the following statement about sampling is TRUE A. Sampling error can be eliminated by strictly follow a probability sampling frame B. Snowball sampling, as a form of convenience sampling, enables researchers to achieve completely random samples C. Convenience sampling strategies are only applicable to qualitative studies The advantage of stratified sampling is that the sample is distributed in the same way as the population in terms of the stratifying criterion D. Sampling error generally increase as sample size increases CJ Q3. Monitoring the future is a national representative survey that conducted annually. Each year, the research team first Systematic sample Stratified random sampling Multi-stage cluster sampling Simple random sample Non-probability sample 1 Q4. Which of the following statement is TRUE regarding survey question design A. One advantage of open questions is that the answers do not need to be coded and hence is time-efficient B. The ecological fallacy is a serious limitation of secondary analysis C. Secondary analysis of survey data omitted the possibility for longitudinal research R D. The personal characteristics of interviewers rarely affect the interview Q5. Standardization in interviews and questionnaires aims to reduce/avoid A. Interviewer error in asking questions and recording information B. Interviewee lapses in memory C. Mistakes in entering the data D. Biases related to the personal characteristics of the interviewer E. Poorly designed interview questions A
* Type | Error => Falsefully reject a true null hypothesis Type 2 Error > Fails to reject a null hypothesis that is false Q6. Which of the following types of variable may be used to measure temperature? A. Nominal C. Interval - Does not have true zero B. Ordinal C X D. Ratio I have true zero (In temp, zero degree got meaning, thus sutto is best to measure Q7. When we falsefully rejected a true null hypothesis, this is called A. Type 1 error - B. Type 2 error C. Sampling error D. Statistically insignificant E. We fail to reject the null hypothesis D) X Q8. Among the following p-value, for which one we are most confident that there exist a relationship in the population smaller the P-value the more confident A. P <= 0.0001 B. P <= 0.001 C. P <= 0.01 D. P <= 0.05 E. P <= 0.005 Cx Q9. Researchers found a positive relationship between the numbers of ice cream sold at a beach and the numbers of people drowning during the summer. This is more likely to be A. Type 1 error B. Type 2 error C. Spurious relationship D. There exists an intervening variable C,
