Upper And Lower Quartile Formula. 20 21 2 20 5 lower quartile. For example if you have 10 numbers in your data set you would solve q3 10 1 then solve x 11 which would give you 8.
If the size of the data set is odd do not include the median when finding the first and third quartiles. Quartile takes two arguments the array containing numeric data to analyze and quart indicating which quartile value to return the quartile function accepts 5 values for the quart argument as shown the in the table below. 20 21 2 20 5 lower quartile.
Use the quartile function to get the quartile for a given set of data.
First lets arrange of the values in an ascending order. 40 45 50 55 56 69 75 77 88 90. The lower quartile q 1 is the median of the lower half of the data. For example if you have 10 numbers in your data set you would solve q3 10 1 then solve x 11 which would give you 8.
