To compare your red blood cell (RBC) count to the average count of an adult male, you can use a **z-score**. The z-score tells you how many standard deviations your RBC count is from the average (mean) count.
To compute the z-score, you would use the formula:
\[
z = \frac{(X - \mu)}{\sigma}
\]
where:
- \(X\) is your RBC count,
- \(\mu\) is the average RBC count for adult males,
- \(\sigma\) is the standard deviation of the RBC counts for adult males.
This statistical measure allows you to determine whether your RBC count is above or below the average and by how much, in terms of standard deviations. If you just want to see if your count is within a normal range, you may also consider looking at confidence intervals or percentiles based on population data.
If you have access to the average RBC count and the standard deviation for adult males, this approach will give you a clear understanding of where your count stands in relation to the average.
