Question

the him director asks an analyst to determine the appropriate sample size to use to estimate the time to code inpatient records in his department. what piece(s) of information must the analyst determine?

Answer 1

To determine the appropriate sample size for estimating the time to code inpatient records, the analyst must consider the desired level of precision and confidence, the variability of the time, and the population size.

Step-by-step explanation:

The analyst must determine several pieces of information to determine the appropriate sample size for estimating the time to code inpatient records. These pieces of information include:

1. The desired level of precision: The analyst needs to determine how precise they want their estimate to be. This can be measured by the margin of error or confidence interval.
2. The desired level of confidence: The analyst needs to decide how confident they want to be in their estimate. This is typically represented as a percentage, such as 95% or 99%.
3. The variability of the time to code inpatient records: The analyst needs to have an understanding of how much variation there is in the time it takes to code inpatient records.
4. The population size: The analyst needs to know the size of the population of inpatient records they are working with. This information is used to calculate the sample size.

By determining these pieces of information, the analyst can use statistical formulas or online calculators to determine the appropriate sample size to estimate the time to code inpatient records in the department.
