If the error margin of a study is 20%, what would the accuracy level be?
100%

The error margin of a study refers to the amount of uncertainty in the study's results. It is typically represented as a percentage. In this case, if the error margin of the study is 20%, the accuracy level would be 80%.
To calculate the accuracy level, you subtract the error margin from 100%. Therefore, 100% - 20% = 80%.
To determine the accuracy level of a study given an error margin of 20%, you need to subtract the error margin from 100%, as the error margin represents the portion of potential error or inaccuracy.
So, to calculate the accuracy level, subtract the error margin (20%) from 100%:
Accuracy level = 100% - 20% = 80%
Therefore, the accuracy level would be 80%.
