When is a census better than a sample?
When is a census study appropriate?
WHat makes a good sample?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What does the representitiveness of a sample depend on?
Accuraccy = the degree to which bias is absent from the sample, no systematic variance.
Precision = precision of estimate, (small sampling error, sampling error reflects the influences of change; it is what is left after all known sources of systematic variance have been accounted for).
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
