Sampling Methods
Every member of the population has an equal chance to be selected.
What is a simple random sample?
Unconscious or automatic attitudes/associations towards someone or something
What is hidden bias?
A technique used in experiments to assign participants to groups using randomization methods, ensuring each participant has an equal chance of being place in any condition.
What is random assignment?
A technique used to reduce variability by grouping similar experimental units into blocks before assigning treatments.
What is blocking?
This planet is known for its Great Red Spot.
What is Jupiter?
A sampling method where researchers select members of a population at a regular, fixed interval after a random start.
What is a systematic random sample?
Prompts or encourages an answer
What is a leading question?
A method of using chance-based mechanisms to select samples or assign participants to different groups in an experiment.
What is randomization?
An experimental method that groups similar experimental units into homogeneous sets before randomly assigning treatments within those blocks.
What is a randomized block design?
This Italian dish is made with layers of pasta, cheese, and sauce.
A sampling method where researchers divide a large, geographically dispersed population into smaller, heterogeneous groups called "clusters."
What is a cluster sample?
Respondents underestimate or exaggerate
What is a response bias?
A "dummy" treatment that appears to be the same as the actual treatment but has no effect
What is a placebo?
An experimental method used to compare two treatments or conditions, where participants are paired based on similar characteristics.
What is a matched pairs design?
This 1997 film featured the line, "I'm the king of the world!"
Dividing the population into homogeneous groups called strata
What is a stratified random sampling?
Participants cannot be contacted or refuse to participate
What is a nonresponse bias?
Both researchers and subjects are unaware of which subjects belong to which control group.
What is double-blind?
A sample that remains unchanged or untreated, serving as a baseline for comparing the results of the experimental group.
What is control?
This river flows through Egypt and is the longest river in Africa.
What is the Nile River?
What is multi-stage sampling?
Easy to reach members of a population
What is a convenience sample?
The name for a human experimental unit.
What are subjects?
Using enough experimental units in each group so that any difference in the effects of the treatments can be distinguished from chance differences between groups.
What is replication?
This sport uses the terms "Love", "Deuce", and "Set".
What is Tennis?
