How do you find the percentile rank example?

Percentile Rank = [(M + (0.5 * R)) / Y] x 100

  1. Percentile Rank = [(9 + (0.5 * 2)) / 20] * 100.
  2. Percentile Rank = [(9+1) / 20] * 100.
  3. Percentile Rank = [10 / 20] * 100.
  4. Percentile Rank = 0.5 * 100.
  5. Percentile Rank = 50%

How do you find the percentile rank in a normal distribution?

If you’re given the probability (percent) greater than x and you need to find x, you translate this as: Find b where p(X > b) = p (and p is given). Rewrite this as a percentile (less-than) problem: Find b where p(X < b) = 1 – p. This means find the (1 – p)th percentile for X.
