Box And Whisker Plot Upper And Lower Quartile
Box And Whisker Plot Upper And Lower Quartile. A box and whiskers diagram is also known as box plot, it displays a summary of a set of data. 5, 6, 18, and 20.
The size of each segment represents the difference between one value to another. Minimum, maximum, median, first quartile and third quartile, interquartile, upper limit and lower limit. The horizontal line extends from the minimum to the maximum value, excluding outside and far out values which are displayed as separate points.
The Whiskers (The Lines Extending From The Box On Both Sides) Typically Extend To 1.5* The Interquartile Range (The Box) To Set A Boundary Beyond Which Would Be Considered Outliers.
5, 6, 18, and 20. Two or more data can be compared. If you have an odd amount of numbers, don't include.
Try The Given Examples, Or Type In Your Own Problem And Check.
The box and whisker plot of excel shows the minimum, first quartile, median, third quartile, and maximum set of a data. Draw a rectangle from the q 1 value at 6 to the q 3 value at 20. Minimum, maximum, median, first quartile and third quartile, interquartile, upper limit and lower limit.
Next, Construct The Box Portion Of The Box And Whisker Plot.
The middle line represents the median. On a number line, draw small vertical lines above each of these numbers: Note that the plot divides the data into 4 equal parts.
In Order To Calculate This Value We Must First Understand What The Lower Quartile, Median And Upper Quartile Are:
The first step in constructing a box and whisker plot is to find the median, the lower quartile(q1) then the upper quartile (q2) of a given set of data.then you need to find the interquartile range or the (iqr). Upper quartile ( q 3) = 20. The size of each segment represents the difference between one value to another.
Uw = 6 Values Greater Than Upper Bound Or Less Than Lower Bound Are Considered To Be Outliers.
The left whisker represents the bottom 25 % of the data, the left half of the box represents the second 25 % , the right half of the box. The lower quartile is the 25th percentile, while the upper quartile is the 75th percentile. The (iqr) is the difference between the lower and the upper quartile.
