Explanation / Answer
2.Difference between a rate and a proportion
A rate measures the occurence ofparticular event in a population during a given time period.
A proportion is a ratio which
indicates the relation in magnitude of a part of a whole.
A rate comprises of numerator,denominator,time specification and multiplier.
Here Numerator refers to number of times an event has occured, during a specific time period, whereas denominator related to the population or to the total event.
Examples of Rate:
When we say there were 500 deaths from motor vehicle accidents in city A during 1985,It is just nothing more than counting deaths in that city during that particular year.It compares the frequency of accidents in cityA with that in cityB.To allow such comparisions , the frequency must be expressed as a rate:
Death rate= Number of deaths in one year *1000
Mid-year population
The rate of adult obesity in 2016 is 25.5%.
Obesity rate by age is (2016)
65+ =24.6%
45-65 = 31.4%
26-44 =24.9%
18-25 =1.7%
Examples for proportion:
proportion = Total no of death due to heavy smoking at specific age*100
Total no of subjects with heavy smoking at specific age
Applying the observed age -specific proportions of heavy smokers to the same standard population
Proportion of heavy smokers in adults aged18 has decreased from 22% in 2002 to 14% in 2014 in New York City.
RATE PROPORTIONA rate measures the occurence ofparticular event in a population during a given time period.
A proportion is a ratio which
indicates the relation in magnitude of a part of a whole.
The rate is expressed in per 1000 or some other rounded figure A proportion is usually expressed as a percentage.A rate comprises of numerator,denominator,time specification and multiplier.
Here Numerator refers to number of times an event has occured, during a specific time period, whereas denominator related to the population or to the total event.
