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.
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.
How do you work out outliers on a box plot?
the number in your piece of data = n lower quartile, n+1 divided by 4 upper quartile, n+1 divded by 4 and times by three interquartile range(IQR) = upper quartile - lower quartile outliers(O) = interquartile range x 1.5 lower than IQR-O is an outlier (h) above IQR+O is an outlier (h) the outliers on your box plot are any numbers that are the value i have named (h) ^
What are the five main parts of box and whisker plot?
lower extreme,upper extreme,upper quartile, lower quartile, and the median
How do you find the limit of outliers in box and whisker plot?
To find the limits of outliers in box and whisker plots, you first must determine the Interquartile Range. The Interquartile Range is the difference between the Upper Quartile and the Lower Quartile. For instance, if my Upper Quartile = 87 and my Lower Quartile is 52, then 87 - 52= 35. 35 is the Interquartile Range (IQR).Next, you use the formula 1.5 x IQR to determine if you have any outliers.Example:1.5 x 35 = 52.5Now determine the limit for the Upper Quartile by adding 52.5 to the Upper Quartile.Example:52.5 + 87 = 139.5139.5 is the limit for the Upper Quartile.Next, determine the limit for the Lower Quartile by subtracting the Lower Quartile from 52.5Example52 - 52.5 = -0.5-0.5 is the limit for the Lower QuartileThus, the LIMITS are -0.5 and 139.5. In order for a number to be considered an outlier, it must either be less than -0.5 or greater than 139.5
Does a box plot represent an interquartile range?
If presents you with the upper and lower quartile range, although you have to do calculations in order to find the interquartile range, so no, it does not,
What is the range of a box and whisker plot?
the range is also known as the IQR or inner quartile range's. The inter quartile range is the difference between the upper quartile and the lower quartile.heresy a good example.Example:18 27 34 52 54 59 61 68 78 82 85 87 91 93 100~First find the median -----> 68~then the lower quartile --> 52~next the upper quartile --> 87after you find these you may subtract the lower quartile (aka UQ) from the upper quartile (aka the UQ)In our case the IQR = 87 - 52 = 35.
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.
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.
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.
How do you make a box and whiskers plot?
I personally hated these. So say you have a set of numbers. 78, 80, 81, 83 ,and 85. You need to find the lower quartile, upper quartile, and of course median. the highest and lowest points will be on the end. draw a box around the upper, and lower quartile and lines coming out from it connecting to 78 and 85.
What can easily be seen on a box-and-whisker plot?
From left to right, Minimum, Lower Quartile, Median, Upper Quartile and Maximum. You can also see the inter-quartile range, and whether the distribution is symmetrical or has a positive or negative skew.
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.
How do you work out outliers on a box plot?
the number in your piece of data = n lower quartile, n+1 divided by 4 upper quartile, n+1 divded by 4 and times by three interquartile range(IQR) = upper quartile - lower quartile outliers(O) = interquartile range x 1.5 lower than IQR-O is an outlier (h) above IQR+O is an outlier (h) the outliers on your box plot are any numbers that are the value i have named (h) ^

What is this type of number plot displays data organized into four groups using the lower extreme lower quartile median upper quartile and upper extreme?
It is probably a box and whiskers plot.
