Calculate all three quartiles (upper, middle, and lower) as well as the interquartile range (iqr) for the given data set using the quartile calculator. Along with the quartile values, this calculator also provides a box graph, ascending descending arrangement of values, and median of the group.
Quartiles are three values that split your dataset into quarters. These values are the following: Q1 First quartile: 25% of the data are below this value. Q2: Second quartile / Median: This value splits the data in half. Q3 Third quartile: 25% of the data are above this value. Quartiles also correspond to percentiles.
3, 4, 4 | 4, 7, 10 | 11, 12, 14 | 16, 17, 18. In this case all the quartiles are between numbers: Quartile 1 (Q1) = (4+4)/2 = 4; Quartile 2 (Q2) = (10+11)/2 = 10.5; Quartile 3 (Q3) = (14+16)/2 = 15; Also: The Lowest Value is 3, The Highest Value is 18; So now we have enough data for the Box and Whisker Plot: And the Interquartile Range is: Q3 ...
