16/01/2009Â Â· when I used QUARTILE to calculate the first quarter "25%" it gave me 12.5 also, I have used the same function to calculate the third quarter "75%", the output was 19.5 what I am asking about is how I can calculate the first quarter and the third manually, without using QUARTILE function... In First Quartile calculator, it calculates only the 1st quartile for the corresponding data set values. First quartile is denoted as Q1, which is the median of the lower half of the data set. To calculate the 1st quartile, enter the data set in the Q1 calculator.

We take this step first because the most widely-used definition of an outlier is a data point that is more than 1.5 interquartile ranges (IQRs) below the 1st quartile, and 1.5 interquartile ranges above the 3rd quartile. To determine those values, we first have to figure out what the quartiles are.... In First Quartile calculator, it calculates only the 1st quartile for the corresponding data set values. First quartile is denoted as Q1, which is the median of the lower half of the data set. To calculate the 1st quartile, enter the data set in the Q1 calculator.

Quartile Quartiles partition - as the name suggests - the corresponding distribution into four quarters each containing 25% of the data. A particular quartile is therefore the border between two neighboring quarters of the distribution.... It is the difference between the third quartile and the first quartile and is used to find outliers in a given data set. Through inter quartile range, we can see how the data will be spread about the median. This range helps us to find the measure of dispersion in the set of observation.
