Quiz 4.1b Measures of frequency Flashcards
This is used to measure the prevalence of disease in a certain locality

This describes the relationship between two numbers wherein the numerator is part of the denominator and with the added feature of time
-Rate
Can ratio be expressed as fraction?
yes
This tells us the number of people in the population who died due to a certain condition in a given period of time.

-Prevalence
The involvement of time always implies a rate.
-No
This refers to the number of new cases of a certain health condition in a population over a specified period of time.
-Incidence
A low mortality rate always implies that a certain disease is not that deadly.
No
This tells us how deadly a disease is in a given population at a certain period of time.
-Case fatality rate
Can the values for incidence and prevalence be the same?
-Yes
The prevalence is very much similar to this measure of frequency.
-Morbidity
Which of the following can decrease the prevalence of a certain disease in a locality?
- Increasing the population of unaffected individuals
- Increasing the number of people cured from the said disease
- Increasing the mortality of the said disease
This describes the relationship between two unrelated numbers:
