Third Quartile(Q3) = (3(n + 1)/4)thTerm 1stquartile is also known as the lower quartile. 2ndquartile is the same as the median dividing data into 2 equal parts. 3rdquartile is also called the upper quartile. The interquartilerangeis calculated as Upper Quartile – Lower Quartile. Exampl...
Upper and lower quartiles The upper quartile (sometimes called Q3) is the number dividing the third and fourth quartile. The upper quartile can also be thought of as the median of the upper half of the numbers. The upper quartile is also called the 75th percentile; it splits the lowest ...
The quartiles represent place values in the data. That is, we can divide the data into four equal parts and we will have three values called quartiles. The first represents the 25th percentile. Answer and Explanation: We have: {eq}\text{ From smallest to largest we have:...
The interquartile range (IQR) is the value of the 75th percentile (one of the quartiles) and the 25th percentile (another of the quartiles). Each...Become a member and unlock all Study Answers Start today. Try it now Cr...
Subtract Q1 from Q3 : 16 – 7 = 9. Solution: The IQR is 9. Back to Top Find an interquartile range for an odd set of numbers: Alternate Method As you may already know, nothing is “set in stone” in statistics: when some statisticians find an interquartile range for a set of odd...
This new limit is calculated using the Interquartile Range or IQR. This number is the distance between the Upper and Lower Quartile, or in our example it would be 8. That being said the new upper whisker is the first number that is less than the Upper Quartile (3Q) + 1.5IQR, in our...
Draw a line in the box at the median. Draw lines (whiskers) from the edges of the box that reach to the minimum and maximum values on each side. How to interpret a boxplot graph? In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percen...

In other words, where IQR is the interquartile range (Q3-Q1), the upper whisker will extend to last datum less than Q3 + whis*IQR). Similarly, the lower whisker will extend to the first datum greater than Q1 - whis*IQR. Beyond the whiskers, data are considered outliers and are ...
A quartile is a statistical term that describes a division of observations into four defined intervals based on the values of the data and how they compare to the entire set of observations. Quartiles are organized into lower quartiles, median quartiles, and upper quartiles. When the data poi...
