Chapter 9 Flashcards
What are surveys?
Are instruments used to collect important information from individuals
Companies that specialize in the construction and administration of surveys and analysis of survey data.
Survey research firms
What are survey researchers?
People who design and conduct surveys and analyze their results
Helps us determine cause and effect.
What research technique is this?
2pts
Experimental research technique
- Dependent and independent variables
Helps us describe a situation or phenomenon.
2pts
Descriptive research techniques
- Majority of surveys
A survey that is administered by the U.S. Census Bureau every 10 years.
What survey is this and how often is it done in Canada?
2pts
- Decennial Census Survey
- Canada every 5 years
Are those that individuals complete themselves.
Self-administered surveys
Mailed to respondents with instructions for completing and returning them.
Mail surveys
Administered by a facilitator in person for respondents to complete in the presence of the facilitator.
Individually administered surveys
Are surveys that involve direct contact between the survey researcher and the respondents in person or by phone.
Personal interviews
What are non-sampling measurement errors?
Errors associated with the design and administration of the survey
What is item non-response rate ?
The frequency with which an item or question was not answered
Administering a survey to a representative subset of the population. Refers to the number of people needed to represent the target population accurately.
Sample size
What is probability sampling?
A type of sampling that uses statistics to ensure that a sample is representative of a population
Every member of a population has an equal chance of being chosen as a member of the sample.
Simple random sampling
Is used when it is not feasible to list all of the individuals who belong to a particular population and is a method often used with surveys that have large target populations.
- Cluster sampling
- Heterogeneous within clusters, homogeneous between clusters
- Divide population into clusters/naturally occurring groups (schools, hospital, companies) and then randomly select from each of these clusters to create the sample.
Is a type of sampling in which not everyone has an equal chance of being selected from the population.
Non-probability sampling
The survey researcher uses any available group of participants to represent the population.
Convenience sampling
Members of the population are classified into strata or categories (gender, age, region etc), and then a random sampling technique is used to select participants from within the strata in the same proportion as they exist in the population being studied.
Stratified random sampling
- Homogenous sub groups/within (strata), heterogeneous between strata
What type of sampling is this a weakness of?
- Participants are likely not representative of the entire population
- The results likely cannot be generalized to the population
Convenience sampling
What type of sampling is this a weakness of?
Subjects in the naturally occurring groupings may not be equivalent, making it hard to interpret study results.
Cluster sampling
What type of sampling is this a weakness of?
It is not always practical to randomly select individuals from the population.
Stratified sampling
What type of sampling is this a weakness of?
- It can be time - consuming
- It is not always practical or feasible to randomly select individuals from the population
Simple random
What is homogeneity of the population?
How similar people in your population are to one another.
