# Can someone help me with percentiles please?

See a solution process below:

First, sort the set of numbers from lowest to highest:

100, 100, 105, 113, 129, 132, 146, 152, 176, 200

There are 10 numbers in the set.

30th Percentile: To find the 30th percentile, multiply the number of items in the set (for this problem 10) by 30% to give:

90th Percentile: To find the 90th percentile, multiply the number of items in the set (for this problem 10) by 90% to give:

Of course! Percentiles are used in statistics to indicate the value below which a given percentage of observations fall in a group of observations. For example, the 75th percentile indicates that 75% of the observations are below that value. To calculate percentiles, you first arrange the data in ascending order, then use the formula:

Percentile = (P/100) * (n + 1)

Where P is the desired percentile (e.g., 25th, 50th, 75th), and n is the number of data points. If the result is a whole number, it corresponds to the observation at that position in the ordered data set. If it is not a whole number, you take the average of the values at the positions indicated by the whole number part and the next higher whole number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
