Dependent variable changes based on the independent variable.

Experimental research involves manipulation of variables, unlike non-experimental designs.

Debriefing ensures participants understand the study's purpose and addresses any concerns or distress caused.

Standard deviation measures variability, not central tendency.

Surveys are a quantitative research method that collects numerical data.

Informed consent ensures participants are fully aware of the study's purpose, procedures, and risks before consenting to participate.

Random assignment reduces bias by equally distributing potential confounding variables.

Pearson correlation measures the strength and direction of the linear relationship between two variables.

Double-blind procedure ensures both researchers and participants are unaware of who is receiving treatment to minimize bias.

Confounding variables distort the relationship between the independent and dependent variables.

Quasi-experimental designs lack random assignment, which limits causal inference.

Informed consent ensures participants are aware of the study's objectives, risks, and procedures before participating.

External validity refers to the extent to which findings can be generalized to real-world contexts.

Placebo helps to distinguish between the effect of the treatment and the psychological effect of receiving treatment.
