What is the range of the data set in the box and whisker plot?
The whiskers go from the minimum to the maximum though outliers may be excluded. The box, itself, goes from the lower quartile to the upper quartile.
What is the definition to box and whisker plot?
A data display that organizes data values into four parts using the lower extreme,lower quartile,median,upper quartile,and upper extreme.
A box and whisker plot has 4?
A box and whisker plot has four quartiles in which its data is spread across.
How do you find the mode in a box and whisker?
You cannot. The mode is not part of a box and whisker plot.
What is the type of average on a box and whisker plot?
On a standard box-and-whisker plot, the averages used are medians. Arithmetic means are used in some box-and-whisker plots, but most use medians.
What is the lower quartile on a box and whisker plot?
The lower quartile is the line that represents the left-hand edge of the "box", in the box and whisker plot.
What does the box in a box-and-whisker plot represent?
The inter-quartile range.
Show you an example of a box and whisker plot?
range: 32; first quartile 17; third quartile: 34
How do you find out the width of a box and whisker plot?
The sides of the box are the quartile values: the left is the first quartile and the right is the third quartile. The width, therefore is the interquartile range.
What is a whisker plot?
Not sure about a whisker plot, but a box and whisker plot is a representation of statistical data for one variable (at a time).It consists of a rectangular shape, the "box", plotted against a horizontal value axis. The left side of the box is the lower quartile of the data and the right side is the upper quartile. The median divides the box.Extending out from both sides of the box are lines, the "whiskers", that reach to the minimum and maximum values.So, a box and whisker plot is defined byminumum,lower quartile (Q1),median (Q2),upper quartile (Q3), andmaximum.If there are outliers, they are usually excluded from the box and whiskers plot and are marked up separately as crosses.
In a box-and-whisker plot it shows the what of data?
the box shows you the range of #s from the lower quartile to the upper quartile. the wiskers show you all of the #s outside of the box.
What are the five main parts of box and whisker plot?
lower extreme,upper extreme,upper quartile, lower quartile, and the median
What are the values that make up the box-and-whisker plot?
From smallest to largest, they are the minimum, lower quartile, median, upper quartile and maximum.
How many quartiles does a whisker box plot have?
The vertical edge on the left of the box marks the lower (1st) quartile. The vertical edge on the right of the box marks the upper (3rd) quartile. The median (or 2nd quartile) is indicated by the vertical line in the middle of the box. The box may be drawn vertically in which case the bottom of the box is the lower (1st) quartile, the top of the box is the upper (3rd) quartile and the band in the middle is the 2nd quartile (or median). The whiskers on the end of the box vary.
What are the numbers used in making a box and whisker plot?
The box goes from the lower quartile to the upper quartile and has the median marked across it. The whiskers stretch out, from the box, to the minimum and the maximum.
In a box-and-whisker plot what fraction of the data is greater than the first quartile?
57 is not right
What does the upper quartile and lower quartile show in a box and whisker plot?
It is a measure of the spread of the variable. Also, in conjunction with the median, it gives a measure of the skewness.
