Research Methods and Psychological Inquiry Quiz

Qualitative research methods emphasize understanding through in-depth exploration of cases.

Informed consent ensures participants understand the research procedures and can make voluntary decisions about participation.

Descriptive statistics provide a concise summary of data, including measures of central tendency and variability.

Random assignment minimizes bias by distributing participant characteristics evenly across experimental conditions.

Cross-sectional studies only provide a snapshot of a population at one point in time, limiting causal inference.

Quasi-experimental designs lack random assignment, often using pre-existing groups or conditions for comparison.

Non-probability sampling methods involve selecting participants based on convenience or accessibility rather than random selection.

The Hawthorne effect refers to changes in behavior or performance due to participants' awareness of being observed.

Continuous variables can take on any value within a range, such as income level, height, or weight.

Generalizability refers to the applicability of research findings beyond the specific study context.

A correlation coefficient close to -1 indicates a strong negative relationship between variables.

The independent t-test compares means between two independent groups to determine if there's a statistically significant difference.

Statistical power indicates the likelihood of detecting an effect when it truly exists, minimizing Type II error.
