the risk of developing a condition over a specified time period

the amount of variance account for by a predictor or group of predictors in a regression equation

a reliability estimate that suggests the range of outcomes expected when an analysis is repeated

data with values that fall on a continuum from less to more

the degree to which two or more variables fluctuate together

a table used to illustrate the results of a correlation analysis and depects the strength of the relationships between each pair of variables included in the correlation

data that can take on only two values; often used to distinguish the presence or nonpresence of some construct

the proportion of one data set that accounts for the spread of numbers in a second data set

the chance of a particular event occurring in one group compared with the chance of the event occurring in another group

statistical techniques that use study samples to make generalizations that apply to an entire population

used in Hazard ratios to depict the duration of time for two or more groups to reach an outcome

a statistical method in which several provides information about the likelihood of detecting a difference if it exists.provides information about the likelihood of detecting a difference alues are entered into a regression equation to determine how well they predict a continuous outcome

a statistical method in which several calues are entered into a regression equation to determine how well they predict a categorical outcome

the circumstance in which variables (or, in the case of regression, predictors) are correlated with one another

an estimate of the odds when the presence or absence of one varaible is associated with the presence or absence of another variable

an inferential statistic that examines the strength of the relationship between two continuous variables

a calculation that determines the extent to which two or more variables predict a particular outcome

the probability of an event occurring after an exposure in relation to the probability of an event occurring without an exposure

the probability of an event happenning to one froup of exposed individuals as compared with another froup that is not exposed to a particular condition

a graph of plotted points that shows the relationship between two sets of data

an inferential statistic that examines the strength of the relationship between two variables when one or both variables is rank ordered

a measure of how data points are dispersed around the mean, it can be calculated as the square of the correlation
