John has collected over 2,000 Twitter comments and organized these comments in a spreadsheet. He decides to randomly pull 500 comments for a content analysis. John selects a starting point and selects every 25" comment to be included in this sample of 500 comment. What sampling approach did John implement? O a. Quota sampling O b. Systematic sampling O c. Cluster sampling O d. Stratified samplingA stratied sample in which the number of sampling units drawn from each stratum is in proportion to the population size of that stratum is known as O a. Unequal stratified sample O b. Proportional stratied sample 0 c. Disproportional stratied sample 0 cl. Equal stratified sample During a research project, researchers often utilize two or more probability sampling techniques to test the same research questions. This research sampling approach is called O a. Disproportional stratified sample O b. Multistage area sampling O c. Multi-samplingResearchers must consider a variety of sampling criteria and assess the relative importance of these criteria to decide on the most appropriate sample design. The sampling criterion that researchers should consider include: 0 a. Respondent height 0 b. Respondent intelligence 0 c. Degree ofaccuracy Q d. Researcher personality Research studies focusing on consumer behavior influenced by geographic areas, such as South versus North, should implement what type of sample? O a. Quota O b. Cluster O c. Judgment O d. SystematicMaggi is asking her students to complete her online survey to assess online shopping behavior. To increase her sample size, she asks each of her students to find two more people to complete the online survey. Her total sample size is 546. Maggi used a sampling approach. O a. Convenience O b. Cluster O c. Snowball O d. QuotaEven though it is a nonprobability sampling approach, is the most commonly used sample in marketing research. O a. Convenience O b. Simple random c. Cluster O d. SnowballA researcher pressured to meet a deadline or to complete a project quickly will most likely select sampling due to its quick implementation potential. O a.Convenience O b. Cluster 0 c. Quota Q d. Snowball If degree of accuracy is a major concern for a researcher, a highly generalizable sample is preferred. Therefore, a researcher should administer rather than in the research study. 0 a. Probability; nonprobability O b. Snowball; stratied O c. Nonprobability; probability 0 d. Convenience; probability
