Studdy Solution
STEP 1
1. The problem involves selecting a specific sampling method for a given scenario.
2. The scenario describes contacting a random sample of registered voters to obtain their opinions.
STEP 2
1. Understand the definitions of each sampling method.
2. Identify the characteristics of the given sampling scenario.
3. Compare the scenario to the definitions to select the appropriate sampling method.
STEP 3
Understand the definition of a Simple Random Sample (SRS).
A Simple Random Sample means each member of the population has an equal chance of being selected, and the selection of one member does not influence the selection of another.
STEP 4
Understand the definition of a Stratified Random Sample.
A Stratified Random Sample involves dividing the population into subgroups (strata) based on a characteristic, then randomly sampling from each subgroup.
STEP 5
Understand the definition of a Cluster Random Sample.
A Cluster Random Sample involves dividing the population into clusters (groups), randomly selecting some clusters, and then sampling all members within those clusters.
STEP 6
Understand the definition of a Systematic Random Sample.
A Systematic Random Sample involves selecting every member of the population after a random start.
STEP 7
Understand the definition of a Convenience Sample.
A Convenience Sample involves selecting members of the population that are easiest to reach.
STEP 8
Identify the characteristics of the given sampling scenario.
The scenario describes obtaining a list of registered voters and randomly selecting 100 names from this list to ask for their opinion.
STEP 9
Compare the scenario to the definitions of each sampling method.
The scenario involves randomly selecting names from a list, without mention of subgroups, clusters, systematic intervals, or convenience.
STEP 10
Determine the appropriate sampling method based on the scenario characteristics.
The method that best matches randomly selecting names from a list of registered voters is the Simple Random Sample.
Solution:
The appropriate answer is Simple Random Sample.
