Study Notes
Quantitative Research
- Utilizes systematic investigation through quantifiable data to uncover patterns.
- Employs methods like clinical trials, epidemiological studies, and in vitro studies.
Interpreting Quantitative Data
- Mean: Represents the average value within a dataset.
- Median: Identifies the middle value when data is arranged in ascending order.
- Standard Deviation: Measures the spread or variability of data points around the mean.
- Standard Error of the Mean (SEM): Estimates how far the sample mean is likely to deviate from the true population mean.
- Confidence Interval: Defines a range of values that likely contains the true population parameter with a specific level of confidence.
- Replicates: Refers to the number of independent data points or subjects included in an experiment.
-
P-value: Assesses the strength of evidence against the null hypothesis. Indicates the probability of obtaining observed results if the null hypothesis is true.
- P < 0.05: Indicates statistical significance, suggesting less than a 5% chance that the observed results are due to random chance.
- P > 0.05: Indicates a lack of statistical significance, implying that the results are likely due to random variation.
- Null Hypothesis: A statement that assumes no effect or difference between groups or variables.
Advanced Developments in Dental Research
- Digital Dentistry: Leverages CAD/CAM technology for creating dental impressions.
- Regenerative Medicine: Employs bioactive materials to promote tissue regeneration.
- Nanotechnology: Incorporates nanoparticles for enhanced material durability in dental applications.
- Personalized Dentistry: Utilizes genetic data for tailored dental care.
