How do I calculate percentile?
When you know the percentile of a specific value, you can easily calculate the percentile rank using the percentile rank formula:
- Percentile rank = p / [100 x (n + 1)]
- Percentile rank = (80) / [100 x (n + 1)]
- Percentile rank = 80 / [100 x (25 + 1)]
- Percentile rank = 80 / [100 x (26)]
What does 70% percentile mean?

What is the third percentile?
The higher the percentile, the bigger your child is in comparison to others of his gender and age. The lower the percentile, the smaller your child is. Most children would be closer to the 50th percentile. So if your child is above the 97th or below the 3rd percentile, he is part of a very small group of children.
What percentage is q3?
Q2 (the median) is the 50th percentile and shows that 50% of the scores are less than 75, and 50% of the scores are above 75. Finally, Q3, the 75th percentile, reveals that 25% of the scores are greater and 75% are less than 84.
What does 55th percentile mean?

What is the percentile for 61?
20th percentile
The next rank is 11 with 61 data value, so 61 is the 20th percentile. The ordinal rank for the 30th percentile = (30/100) X 50 = 15. The next rank is 16 with 65 data value, so 65 is the 30th percentile. The ordinal rank for the 40th percentile = (40/100) X 50 = 40.

What is the difference between decile and percentile?
Deciles are similar to Percentiles (sounds like decimal and percentile together), as they split the data into 10% groups: 1 The 1st decile is the 10th percentile (the value that divides the data so 10% is below it) 2 The 2nd decile is the 20th percentile (the value that divides the data so 20% is below it) 3 etc!

What is the 3rd quartile or the 75th percentile?
The 1st quartile or the 25th percentile is equal to 25.5. Since 9 is an integer, then we need to get the average of 9th and 10th values in [TABLE 1] = (35+38)/2 = 36.5. Thus, the 3rd quartile or the 75th percentile is equal to 36.5.
What is the p th percentile?
The p th percentile is the value in a set of data at which it can be split into two parts. The lower part contains p percent of the data, and the upper part consists of the remaining data; i.e., 100-p (the total data equates to 100%). Calculating the p th Percentile
