• Control over variables

• Establish cause-effect relationships

error/ flaw in study

Randomly assigning participants to different groups in an experiment helps ensure that each group is similar at the start, increasing the validity of the results.

A subset of individuals chosen from a larger set in a way that each member has an equal chance of being selected, ensuring representativeness. (Assignment and sampling can be done via names in a hat, computer generation, etc))

A subset of a population that accurately reflects the demographics and characteristics of the entire group, enabling generalizations to be made.

Where the population is divided into subgroups, or strata, and a random sample is taken from each subgroup to ensure representation.

Helps identify relationships between variables, measures the strength and direction of relationships, aids in making predictions based on patterns in data.

It does not imply causation, can be affected by outliers, and may not account for confounding variables."

Causation

variables increase & decrease together

as one variable increases the other decreases

The stronger the relationship REGARDLESS of the pos/neg sign.

= points closer together on graph

Occurs when a third variable influences both the independent and dependent variables, leading to a false association between them.

Perceiving a relationship between variables that doesn't exist or is weaker than assumed.

Research method to collect data from a population to analyze trends or gather information on opinions, behaviors, or characteristics. Often done through questionnaires or interviews.

Tendency to respond in a way that is viewed favorably by others, rather than truthfully, to avoid negative judgment or gain approval.

The impact of phrasing on responses in surveys or questionnaires, influencing how individuals interpret and answer questions.

Real-world behavior, high external validity, allows for studying complex behaviors in natural settings, minimal researcher interference.

Limited control over variables, potential for observer bias, difficulty in replicating findings.

In-depth analysis, unique situations, detailed data collection, and rich insights for rare phenomena or complex issues.

• Limited generalizability

• Potential bias in data collection

• Time-consuming

• Subject to researcher interpretation

Summarize and describe data using measures like mean, median, mode, and standard deviation. It helps to understand patterns and trends in a dataset.

Statistical values used to summarize the center of a data set, including mean, median, and mode. They provide insight into the typical or average value in a distribution.

The Average (use in normal distribution)

Middle number (use in skewed distribution)

Most occurring number

Skews are a measure of the asymmetry of a distribution. Positive skew means a longer right tail, negative skew means a longer left tail.

Techniques used to analyze data and make predictions or inferences about a population based on a sample.

The likelihood that a result or relationship is not due to chance, but rather a real effect in the population.

Principles that ensure research participants are treated with respect, confidentiality, and informed consent, promoting ethical behavior in research.

Identities kept secret

A structured conversation post-experiment to inform participants of the study's purpose, address concerns, and ensure their well-being.

Chemicals that transmit signals across a synapse from one neuron to another, influencing various functions like mood, muscle movement, and memory.

Brief electrical impulse that carries information along a neuron, resulting from the movement of ions across the neuron membrane. Movement of Na and K ions across membrane sends an electrical charge.

Basic unit of the nervous system, responsible for transmitting information through electrical and chemical signals.

Branch-like extensions of a neuron that receive messages from other neurons. They play a crucial role in transmitting electrical signals within the brain.

The body as distinct from the mind; in neuroscience, refers to the cell body of a neuron that contains the nucleus and maintains the cell's functions.

Part of a neuron that transmits electrical impulses away from the cell body to other neurons or muscles. It is covered by the myelin sheath to speed up signal transmission.

• Key site for communication in the nervous system.

• Gap between neurons

Principle stating that once a neuron reaches its threshold, it fires at full strength, not varying in intensity.R
