Estimating relationship among variables
"related to" "associated with" "linked" - ANS ✓Regression Analysis
Combination of age, sex, wt., family hx is linked to DM
Values of observed data are expressed as functions of a number of possible
causes in order to find which are most important - ANS ✓Factor Analysis
Quantitative test that compares mean score of a sample to known mean - ANS
✓ T test
Quantitative, group of similar subjects divided into 2 groups- intervention x
and y - ANS ✓Two-Sample T test
Looks for differences withing same group at different points in time - ANS
✓ Paired T Test
Used when comparing apples to apples but not sure
alternative to two sample t test looks for ranked
differences or equality - ANS ✓U test

tests if 2 population variances are equal - ANS ✓F test
Similar to T test but used when there are 2 or more means
can compare multiple groups - ANS ✓ANOVA
Qualitative, values is in the category. Compares values of what you expect vs
what you observe. Often used to assess competency or knowledge - ANS ✓Chi
Square test
Tests relationship between 2 quantitative variables- used with interval and
ordinal. Type of regression analysis done frequently. As person ages, height
increases - ANS ✓Pearson's Correlation Coefficient
Used to study linear relationship between depended variable (risk of skin
cancer) and independent variable (sun exposure) - ANS ✓Linear Regression
Processes large amount of data quickly. Need it now - ANS ✓Multidimensional
database
Participants identified through a number key system - ANS ✓Research
Identified
national practitioner data base - ANS ✓used when onboarding physicians
