A percentile is a value with a certain percentage of the data falling below it. In general terms, k% of the data falls below the kth percentile. The first quartile (Q1, or the lowest quartile) is the 25th percentile, meaning that 25% of the data falls below the first quartile.Quartiles are the 25th, 50th, and 75th percentile marks for your data set. These values are used in calculating outliers for a data set. The second quartile is also referred to as the median, and is the central point in the data set when the data is listed in sorted order (if the data set has an even number of points, there are two middle ...

Ex: Find the third quartile Q3 which is the IQ score separating the top 25% from the others. With a Mean of 100 and a Standard Deviation of 15. 1-.25=.75 in Inv Norm (.75,100,15)=110 My answer is 110Standard deviation (SD) measured the volatility or variability across a set of data. It is the measure of the spread of numbers in a data set from its mean value and can be represented using the sigma symbol (σ). The following algorithmic calculation tool makes it easy to quickly discover the mean, variance & SD of a data set.Solution: In this problem, you want to find the 75th percentile in the data set. At least 75% of the data values will be less than this number. Take note that there are 14 data values in this data set. Therefore, N = 14 N = 14. We need to sort them in ascending order.Step 1: Find the mean for the given set of values. Step 2: Find the distance. (i.e) Subtract the mean value from each given values, and ignore minus symbol if any. Step 3: Finally, find the mean of the obtained distance, which is called the mean deviation.
