In mathematics, a percentage is a way of expressing a number as a fraction of 100 (per cent meaning "per hundred". It is often denoted using the percent sign, "%". For example, 45% (read as "forty five percent" is equal to 45 / 100, or 0.45.
Percentages are used to express how large one quantity is relative to another quantity. The first quantity usually represents a part of, or a change in, the second quantity. For example, an increase of $ 0.15 on a price of $ 2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is therefore a 6% increase.
Although percentages are usually used to express numbers between zero and one, any dimensionless proportionality can be expressed as a percentage. For instance, 111% is 1.11 and −0.35% is −0.0035.
eg 5 10 15, the mean would be 10 and if we want the mean percentage its the percentage of the total so 10/20x100/1, which is 50%
i want to calculate the percentage of mean value of particular data.
If you mean 0.45 then as a percentage it is 45%
To find the mean percentage score, first add all the individual percentage scores together to get the total score. Then, divide this total by the number of scores to calculate the average percentage. The formula can be expressed as: Mean Percentage Score = (Sum of Percentage Scores) / (Number of Scores). This gives you the average percentage across all the scores.
