Flashcards in Lesson 7: Categorical Outcomes, Odds Ratio & Risk Assessment Deck (11):

1

## Proportion

### A mathematical comparison between two numbers. The numerator is included in the denominator.

2

## Contingency Table

### Frequency distributions of multiple variables represented in a single table

3

## Odds

### The number of ways an event can occur relative to the number of ways an event cannot occur; does NOT include the numerator in the denominator [ex: 4/6 while the proportion would be 4/10]

4

## Odds Ratio

### The odds of exposure among diseased (cases) vs non-diseased (controls)

5

## Relative Risk

### The likelihood of developing the disease/outcome given that one is exposed divided by the likelihood of developing the disease/outcome given that one is non-exposed

6

## Measure of disease association

### The magnitude of the effect of an exposure on an outcome

7

## The odds ratio is most commonly presented in a ..

### contingency table, which displays the frequency distribution of multiple variables in a single table

8

## Which variable from this unit is a measure of effect size? That is, it determines the strength of the relationship between two variables.

### Odds Ratio

9

## If relative risk = 1..

### there is no association between risk in exposed and risk in non exposed

10

## If RR (relative risk) is greater than 1..

### there is an increased risk for those exposed
