How do box plots describe data?
Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data. From the smallest to the largest, the statistics plotted are:The minimum valueThe lower quartile (the value of the variable that is greater than a quarter of the observations)The median (the value of the variable that is greater than half the observations)The upper quartile (the value of the variable that is greater than three quarters of the observations)The maximum value.(In slightly refined versions, outliers are separately identified).The median is a measure of central tendency (average value). The difference between the quartiles is a measure of dispersion or spread around the average. The relative values of the five indicate whether or not the data set is skewed.Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data.

A nominal scale variable is?
Descriptive, non-numeric, qualitative. Furthermore, they cannot be ordered (as in small, medium, large)
Difference of descriptive statistics and inferential statistics?
Descriptive statistics label, name, or give information about a variable. Inferential stats are inferred from a smaller data set to be valid for the whole population.

What is the difference between a qualitative and quantitative variable?
in mathematical statistics qualitative means not numbers so it has to be expressed in words e.g. a color quantative: means a number e.g. age.
Is class rank a qualitative or quantitative variable?
A qualitative variable is a variable that has categorized values and the difference cannot be measured. A quantitative variable is a variable that consist of ordinary values and the difference can be measured. Depending on the type of class rank it can be both qualitative as quantitative.
