A Randomized Control Trial (RCT) is a type of scientific experiment that randomly assigns participants to an experimental group or a control group to measure the effectiveness of an intervention or treatment.| Simply Psychology
Experimental design refers to how participants are allocated to different groups in an experiment. Types of design include repeated measures, independent groups, and matched pairs designs.| Simply Psychology
Correlation means association - more precisely, it measures the extent to which two variables are related. There are three possible results of a correlational study: a positive correlation, a negative correlation, and no correlation| Simply Psychology
Internal validity refers to whether the design and conduct of a study are able to support that a causal relationship exists between the independent and dependent variables. It ensures that no other variables except the independent variable caused the observed effect on the dependent variable.| Simply Psychology
Demand characteristics refer to clues or signals in an experimental setting that hint to participants about the experimenter's expectations, leading them to behave in a certain way to match these expectations, potentially biasing the results.| Simply Psychology
A controlled experiment aims to demonstrate causation between variables by manipulating an independent variable while controlling all other factors that could influence the results. Its purpose is to show that changes in one variable (the independent variable) directly cause changes in another variable (the dependent variable).| Simply Psychology
Extraneous variables are factors other than the independent and dependent variables that may unintentionally influence the results of an experiment. They need to be controlled, minimized, or accounted for through careful experimental design and statistical analysis to avoid confounding the relationship between the independent and dependent variables.| Simply Psychology
The experimental method involves the manipulation of variables to establish cause-and-effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups.| Simply Psychology
Montessori education is a child-centered approach that encourages self-directed learning through hands-on activities and collaborative play. Developed by Dr. Maria Montessori, it nurtures the whole child - physically, socially, emotionally, and cognitively, emphasizing independence and respect for a child's natural psychological development.| Simply Psychology
