How do I find the percentile of a set of data?

Medal and fan!

Answer 1

Also, how do I find a z-score?

Answer 2

\[z=\frac{x-\mu}{\sigma}\]

Answer 3

That's the formula to find the z-score, I assume? What do the variables represent?

Answer 4

x = variable
\(\mu\) = mean
\(\sigma\) = standard deviation
z = z-score

"A percentile is a value such that for the pth percentile, 0 < p < 100, p% of the data is less than the percentile value."
