Scientific Method
What is the first step of the scientific method
Observation
This type of variable is what the experimenter changes or manipulates.
Independent Variable
Psychologists must make sure participants understand what they’re agreeing to before a study.
Informed Consent
This is the entire group a researcher wants to study.
Population
This fruit holds the record for being the most thrown at people during Spain’s La Tomatina festival.
Tomato
A testable prediction based on prior knowledge or theory is called this.
Hypothesis
This type of variable is what is measured in an experiment.
Dependent Variable
If participants might feel embarrassed or stressed, researchers must warn them about this.
Potential risks
A smaller group taken from the population for a study is called this.
Sample
The longest fingernails ever recorded belonged to Shridhar Chillal of India, and together they measured more than this many feet.
29 feet
This step involves collecting information through controlled procedures to test the hypothesis.
conducting an experiment
In a study testing whether sleep affects memory, the number of hours of sleep is this kind of variable.
Independent Variable
After a study, psychologists must explain the purpose, results, and any deception used to participants.
Debrief
This type of sampling gives everyone in the population an equal chance of being chosen
Random Sampling
This fast-food chain once made the world’s largest hamburger, weighing over 2,000 pounds.
McDonald's
After running an experiment, researchers look for patterns and relationships in their data during this step.
analyzing results
In that same sleep and memory study, the number of words recalled on a memory test would be this kind of variable.
Dependent Variable
Psychologists must protect this, meaning they cannot share personal details about participants without permission.
Confidentiality
When a sample doesn’t reflect the population accurately, we call it this.
Sampling Bias
he record for the most T-shirts worn at once is 260. The man who set it was from this U.S. state known for Mickey Mouse.
Florida
When researchers repeat a study to see if the findings hold true, they are doing this.
Replication
This type of variable is kept the same for all groups in an experiment to make sure the test is fair.
Controlled variable/ constant
If a psychologist discovers that continuing a study could cause serious harm to participants, what are they ethically required to do?
Stop/terminate the study
Dividing a population into groups (like age or gender) and selecting some from each group is this type of sampling.
Stratified sampling
Ashrita Furman holds the world record for holding the most world records — over this many, proving he’s a true champion of records.
