## Question

Step 1/3

Here are definitions and examples of ratio, proportion, and rate:

- Ratio: A ratio is a comparison of two quantities. In the context of disease occurrence, a ratio compares the number of individuals with a certain characteristic or condition to the number of individuals without that characteristic or condition.

Example: Suppose we want to compare the number of males to females in a population. If there are 500 males and 1000 females in the population, the male to female ratio would be 500:1000 or 1:2.

Step 2/3

2. Proportion: A proportion is a type of ratio where the numerator is a subset of the denominator. In the context of disease occurrence, a proportion compares the number of individuals with a certain condition to the total number of individuals in the population.

Example: Suppose we want to calculate the proportion of individuals with diabetes in a population of 10,000 individuals. If 500 individuals in the population have diabetes, the proportion of individuals with diabetes would be 500/10,000 or 0.05.

Step 3/3

3. Rate : A rate is a type of proportion that takes into account the amount of time during which the condition or event of interest occurred.

Example: Suppose we want to calculate the incidence rate of lung cancer in a population of 100,000 individuals over a one-year period. If 100 individuals in the population were diagnosed with lung cancer during that time, the incidence rate of lung cancer would be 100/(100,000 x 1) or 0.001 (or 1 per 1,000).

It is worth noting that rates are usually expressed in a standardized form, such as per 1,000 or 100,000 individuals, in order to make comparisons between populations easier.

Final answer
