Question

A newly proposed endoscopy method used to screen for colon cancer is tested among a random sample of the population. Given that 16 individuals from a test population of 100,000 individuals has colon cancer and 14 individuals test positive for colon cancer, the researchers should determine the sensitivity of the newly proposed screening method is 0.875.

Please explain why this is true

Answer 1

The value of sensitivity obtained is equal to the one given in statement.

Explanation:

Sensitivity is the ratio of number of positive test results to the number of individuals having disease. It is the ability of the test to detect all those with disease in the screened population.

Its formula is written as:

Sensitivity =
`(number of true positives)/(total with disease)`

So, in this case we have values

sensitivity = 14/16 = 0.875 So, the given statement is true.
