"While it's possible to predict the temperature, say, with a reasonable degree of certainty, precipitation is much chancier. The best forecasters can do is to give the probabilities, which they do by having the computer compare present conditions with historical data. When you hear there's a 10 percent chance of rain, that means that out of the last 100 times the weather conditions were just like they are now, it rained 10 times. (More or less--I'm obliged to oversimplify a bit.)" "As for your last couple of questions: a 100 percent chance of rain means that out of the last xnumber of times things were just like they are now, it rained every time. (It does not, incidentally, mean it's raining right this second.) On the question of how reliable the figures are, the amazing truth is that they are absolutely 100 percent reliable all the time--that is, presuming the raw data were fed in properly and the calculations done correctly. Remember, we're just talking about probabilities here. A probability isn't "wrong" if it tells you there's only a 10 percent chance of rain and it rains anyway; it's only wrong if a series of such predictions doesn't pan out over the long haul. Not much comfort if your dermis gets damp next time you're out on a picnic, but it'll have to do." --CECIL ADAMS answer from: http://www.straightdope.com/classics/a2_115b.html
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%

The term "mean" is another way of saying "average." In order to calculate a mean percentage score, you must add together all the percentages, and divide the total by the amount of percentage scores being used.
The formula for calculating the mean percentage score is to first add up all individual scores, then divide the total by the number of scores. This will give you the mean score. To convert the mean score to a percentage, you would then divide the mean score by the total possible score and multiply by 100. This will give you the mean percentage score.
It is the arithmetic average of a number of percentages.
In weather forecasts, a percentage typically refers to the probability of a specific weather event occurring, such as precipitation. For example, a 40% chance of rain means there is a 40% likelihood that rain will fall in the forecast area during a specified time period. This percentage is based on meteorological data and models, indicating the confidence level of the forecasters in the predicted conditions.
Shizzy Weather
Weather related basically means that it has to do with weather.
what dose the weather mean & what is it about & where and why do we have weather
roughly 76% of the world's population of penguins live in what is considered to be warm weather.

i want to calculate the percentage of mean value of particular data.
like the sun is a weather pattern
it means if the weather goes as it is planned
news and weather travel together
If you mean 0.45 then as a percentage it is 45%
