    Engineering stats question.



    (ii) Choose one measure of location and one measure of variability to summarize
    the distribution of yield for each process.
    (iii) State why the measures you choose in part (ii) are appropriate.
    (iv) Compare and conclude about the processes A and B from these box plots.

    I still don't understand even after I've read the answer sheet,on the answer sheet is said something about the distribution being skewed,if possible could you elaborate on that too? Thanks.

    The measuers of location on a boxplot are min, max, median, upper and lower quartiles.

    Pick of of these for each plot and compare them

    For this you can pick the interquatile range or the range and compare between plots.

    What do your class notes and textbook say about it? Have you used a search engine like Google to look into it?

    My class notes doesn't say a thing about it.I tried googling it and only found info about how to tell if the box plot was skewed right or left,but i wanna know what it means if it is skewed right/left,does it affect the mean or median?
