PICO

a mnemonic for framing clinical research questions, standing for Patient, Intervention, Comparison, Outcome.

ex. older adults (65+), stress, no stress, developing type 2 diabetes

theorectical framework

a structure that supports the theory behind research by guiding the study's design and methods. GIVES BASIS

conceptual framework

a system of ideas and beliefs that supports the theoretical underpinnings of a study, providing direction for research.

study significane, why is it needed?

justifies its relevance and potential impact on the field. highlighting what problem it addresses, what knowledge gaps it fills, and who benefits from its findings.

found in introduction

statistical significance

refers to the likelihood that a relationship or effect observed in data did not occur by chance. It is commonly assessed using p-values in hypothesis testing. found with bell curve

p<0.001 less = ?

indicates statistical significance

p>0.001 more = ?

indicates no statistical significance

conclusion, logical reasoning

trustworthiness involves CCDTA?

credibility,

triangulation

multiple data sources to draw conclusions

bias

distortion that affects objective judgment and leads to skewed results.

research control

used in QUANTITATIVE STUDIES to eliminate variables that may influence the outcome.

confoudning variables aka

extraneous factors (ex. age, gender) that can impact the results of a study.

randomness (BIAS REDUCTION METHOD)

the lack of any predictable pattern or order in the selection process, ensuring that each participant has an equal chance of being chosen. QUANTITATIVE

blinding/masking (BIAS REDUCTION METHOD)

a technique used in experiments where participants or researchers do not know which group (control or experimental) participants are assigned to, reducing bias in QUANTITATIVE studies.

qualitative vs quantitive studies

Qualitative studies focus on understanding phenomena through subjective data, while quantitative studies emphasize numerical analysis and statistical methods.
