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 .875.
a. True
b. False

Answer 1

Answer: True

Step-by-step explanation:

Sensitivity in such a scenario is used to measure the accuracy of the screening method. In other words, how effective is the screening method at detecting Colon Cancer.

The sensitivity of the method can be calculated by dividing the amount of people that it showed as positive by the number of people that were actually tested.

The number of people who showed positive were 14 and the amount of people tested were 16.

Sensitivity therefore is,

= 14/16

= 0.875

They should indeed determine the sensitivity of the newly proposed screening method to be .875.
