How can we convert 75 percentile into percent?

You cannot. The 75th percentile is the value of a variable such that 75% of the observations are below that value and 25% are higher. The 75th percentile in the heights of adult women will be a measure of height whereas the 75th percentile in the income distribution in a country will be the level of income [in some currency unit] such that 75% of incomes in the country are lower. These examples illustrate that the 75th percentile can be a measurement in any unit and converting to a percentage makes no sense.

You need to look up z-score tables.


What is the percentile rank if the raw score is 34?

It is not possible to convert a raw score into a percentile without knowing the distribution of scores and key parameters of the distribution. Since none of this information is provided, it is not possible to give a sensible answer.


What is the fifth and 9fifth percentiles of a mean temperature of 98.2 and the standard deviation is 0.62?

The 5th percentile of a standard normal distribution is -1.645 (from the normal probability table). z = (x - &mu;) / &sigma; -1.645 = (x-98.2) / .62 (0.62)(-1.645) = x-98.2 -1.0199 = x-98.2 x = 98.2-1.0199 = 97.1801 The 5th percentile is 97.18 The 95th percentile of a standard normal distribution is 1.645 (from the normal probability table). z = (x - &mu;) / &sigma; 1.645 = (x-98.2) / .62 (0.62)(1.645) = x-98.2 1.0199 = x-98.2 x = 98.2+1.0199 = 99.2199 The 95th percentile is 99.22

How do you convert a percentage to a percentile?

You can't convert that directly. To convert percentages - or any kind of numbers, for that matter - to percentile, you need to use the definition of percentile. For example, if you have a grade of 90%, you check how many other grades have less than 90%, and divide that by the total number of grades. Note that for example with a grade of 90%, your percentile can be anywhere between 0 and 100 - depending what grades OTHERS had.

How do you convert 11.27 percentile into percentage?

A percentile is a measure of the relative position of the outcome of an experiment. 11.27 percentile means that 11.27% of the outcomes were lower and 88.73 were higher. However, it does not provide any information on the level of that outcome.

How do you convert percentile 8.6 to percentage?

You would need to know how many questions were on the original test and what number of questions correct would be in the 8.6 percentile. Most tests do not give this data. If you can find it out, then number right / total number on test x 100 gives the percentage. 50 percentile might mean a 70% if it was an average test, or for a hard test 10 percentile might mean a 30%. Without the above information you cannot directly convert one to the other.
