Research design

The approach to acquiring knowledge through various methods such as correlation, observation, case studies, and surveys.

Correlation

A statistical technique to measure and analyze the strength and direction of the relationship between two variables.

Observation

A research method that involves watching and recording behaviors and events as they occur.

Descriptive statistics

Statistics that summarize and describe the features of a dataset.

Central tendency

Measures that identify the center point or typical value of a dataset, commonly represented as mean, median, or mode.

Variability

A measure of how spread out the values in a dataset are.

Inferential statistics

Techniques used to generalize findings from a sample to a population, allowing predictions or inferences.

Independent variable (IV)

The factor that is manipulated or controlled by an experimenter.

Dependent variable (DV)

The factor that is measured by an experimenter, which may be influenced by the independent variable.

Informed consent

An ethical guideline requiring that participants be fully informed about the research and its risks before agreeing to participate.

Statistical significance (p-value)

A measure of the probability that an observed result would occur by chance; commonly used thresholds are p

Normal curve

A symmetrical bell-shaped distribution that represents the distribution of scores in a dataset.

Standard deviation (s.d.)

A statistic that quantifies the amount of variation or dispersion in a set of values.

Mean

The average of a set of numbers, calculated by dividing the sum of the values by the count of values.

Research ethics

A set of principles that guide researchers to conduct studies responsibly and ethically, ensuring the rights and welfare of participants are protected.

Experimental outcome

The results obtained from an experiment, which can be influenced by various factors including the experimental design.
