Mixed Bag
100

This type of research method manipulates one variable to determine its effect on another while controlling for other variables.

Controlled Experiment

100

This measure of central tendency is the most frequently occurring score in a distribution.

Mode

100

This is the part of the neuron that receives incoming signals from other neurons.

Dendrite

100

This part of the brain is responsible for basic life functions like breathing and heart rate.

Medulla

100

This is the small gap between neurons where neurotransmitters are released.

synapse

100

In this research design, neither the participants nor the researchers know who is in the control or experimental group.

Double Blind

100

A data set includes the following scores: 7, 3,5,8,5 What is the median of this data set?

5

100

This neurotransmitter is often associated with reward and pleasure, and its imbalance is linked to both Parkinson’s disease and schizophrenia.

Dopamine

100

Damage to this lobe of the brain can impair the ability to plan, reason, and control emotions.

Frontal lobe

100

In an experiment, this variable is the one that researchers manipulate.

Independent Variable

100

A researcher wants to study the effects of caffeine on memory but cannot randomly assign participants to groups. What research design is she using?

Quasi Experiment

100

If a data set has a mean of 50 and a standard deviation of 5, what percentage of scores falls within 1 standard deviation above and below the mean?

68%

100

A runner feels a sense of euphoria after a long run due to the release of this neurotransmitter.

Endorphin

100

This brain structure is crucial for the formation of new memories.

hippocampus

100

This neurotransmitter helps regulate mood, sleep, and appetite, and imbalances are linked to depression.

Serotonin
100

The ethical requirement that participants must be fully informed about the procedures and risks of a study before agreeing to participate.

Informed Consent

100

You conduct a study and find a correlation coefficient of -0.85 between hours spent watching TV and GPA. How would you interpret this finding?

Strong negative correlation

100

This neurotransmitter is involved in muscle contraction and memory, and a deficiency is associated with Alzheimer's disease.

Acetylcholine

100

A patient has difficulty speaking but can understand language perfectly. What part of the brain is likely damaged?

Broca's area

100

This term describes the process in which neurotransmitters are reabsorbed by the sending neuron after they have transmitted a neural impulse.

reuptake

100

A researched predicts a relationship between ice cream sales and drowning rates. Predict the type of Correlation.

Positive Correlation

100

Katie and Jack have 10 kids, all below the age of 15. What is the skew of the age of this family. 

Positive skew. 

100

Botox blocks the receptor sites of Ach and causes paralysis and therefore used for wrinkles. What type of drug is it?

ACh Antagonist
100

This part of the brain helps regulate hunger, thirst, and body temperature, and is part of the limbic system.

hypothalamus

100

A set of test scores has a mean of 60 and a standard deviation of 5. If a student scores 70, what is their z score?
