What does a box and whisker plot show about the data?
It is marked by the minimum, and maximum, the median, as well as the lower and upper quartiles. It also shows the skewness of the data.
What is the five-number summary needed for a box plot of this data?
The box plot uses the minimum, lower quartile, median, upper quartile and maximum. The questioner has not provided the data which would enable their values to be calculated.
How can you tell if data is skewed on a box plot?
If the median is exactly in the middle of the box, and the box is exactly in the middle of the whiskers, then skewness = 0. The data are skewed if either the median is off-centre in the box, or if the box is off-centre overall.
What is a biplot?
A biplot is a variety of statistical plot, which is a generalization of the simple two-variable scatter plot, and allows information on both samples and variables of a data matrix to be displayed graphically.
When do you use a box-plot?
A box plot may be used at a preliminary stage to determine the centre and spread of a set of data. The box [and whiskers] plot measures the central point by the median and the range from the maximum and minimum or the quartile points.
What if the data doesnt have a median how do we make a box and whisker plot?
If the data are quantitative they must have a median. If there is no median it is only because the data are qualitative and, in that case, a box and whiskers plot is meaningless.
Can quantitive data be displayed on a scatter plot?

What is the definition of box plot?
a graphic way to display the median, quartiles, and extremes of a data set on a number line to show the distribution of the data.

When is it helpful to sort data by using a stem and leaf plot?
If you have between about 15 and 50 pieces of data, a stem-and-leaf plot is not tedious to make and will illustrate the distribution of the values. Once you have made a stem-and-leaf plot, it is easy to locate the median.
What is the five-number summary needed for a box plot of this data?
The box plot uses the minimum, lower quartile, median, upper quartile and maximum. The questioner has not provided the data which would enable their values to be calculated.
