# Research Flashcards

What is an independent variable?

a constant variable that can be manipulated by the researcher

What is a dependent variable?

a variable that is dependent on results which are measured by the researcher

What is a covariate?

a phenomenon that affects the dependent that is not of interest to the researcher, but the researcher is unable to control

What is a extranenous or confounding variable?

a phenomenon that are not of interest but may have an effect on the value of the dependent variable

What is intra and inter rater reliability

how consistent one person is at measuring something vs how consistently a group of individuals can consistently measure something

What is ANOVA (analysis of variance) used for?

statistical procedure to estimate reliability

What is randomized, repeated measures, and factorial research designs

randomized: everything is randomized; repeated: all subjects measured against the same variables; factorial has multiple independent variables and measures all subjects against all variations

What is used to calculate the association between two variables?

correlation coefficient

What statiscal test is used to predict?

regression analysis

What statiscal test is used to see if a Tx has an effect?

chi square, ANOVA, or T-test

Study types in a hierarchial manner?

RCT, cohort study, case-control study, case series, descriptive study

What is a meta anaylsis?

a variety of systematic reviews (a thorough review and summary of the research)

How to remember specificity and sensitivity

Sp In Sn out

Reliability

Stability, repeatability, and dependability of a test or measure

Intra-rater Reliability

Consistency of a measure made by the same person
