Sum of Its Parts
This experimental design type involves separating participants from the beginning based on a potential confounding variable
What is...
A block design?
What is a pro of using a cluster random sample?
What is...
Convenience
Efficiency
When explaining how to do a simple random sample, I must include what parts of the process? (Need @ least 2 of 4)
What is...
1. Number Assignment
2. Randomization
3. Link to response variable
4. Context
This sampling method involves:
1. Assign all participants a number
2. Random number generate an amount of unique numbers and select those numbers to be participants

A Simple Random Sample?
What is a con of a stratified random sample?
What is...
Inefficiency
Mr. Goka wants to find out of if the height of a basketball player correlates with their vertical jumping ability. He decides a stratified random sample would be best.
What should the strata be based on and what would the different strata be? (Need both)
What is...
3 Strata based on height
1. 6'2 and under
2. 6'3 through 6'7
3. 6'8 and above
This experimental design involves putting two participants together and using a method to randomly assign them to a group which will designate which treatment (or treatment order) they receive.

A Matched Pair Design?
A pro of a block design is that it can reduce bias from...
What is...
Confounding or Extraneous variables
Marshall is trying to draw a block design flowchart for his experiment. He will need what steps in the design? (3 of 5)
What is...
1. Defined Blocks
2. Random Assignment
3. Groups
4. Treatment received
5. Comparison
This sampling method involves:
1. Creating groups based on a shared characteristic related to the response variable
2. Assign each member of a group a number
3. Random number generate an equal amount of unique numbers from each group
What is...
A Stratified Random Sample?
A pro of a simple random sample would be...
What is...
High likelihood of representation
Reduced variability
Matthew wants to know what he needs to include when describing his cluster random sample method. He will need what (2 of 4)
What is...
1. Defined clusters
2. Number assignment
3. Randomization
4. Link to response variable with context
This sampling method involves:
1. Creating groups based on convenient organization or perceived representativeness of each group
2. Assign each group a number
3. Random number generate a set of unique numbers and poll all members of the selected group
What is...
A Cluster Random Sample?
A con of a cluster random sample would be...
What is...
Potential lack of representation
Increased variability
The purpose of randomization needs to include...
What is...
Similar groups
Show causal relationship
Reduce extraneous variables
