The box plots below show the lifespan, in months, of laptop batteries manufactured by four companies: box plot labeled Company A shows minimum at 19, first quartile at 19.5, median at 23, third quartile at 23.5, and maximum at 24. Company B shows minimum at 21, first quartile at 22, median at 24, third quartile at 25, and maximum at 26. Company C shows minimum at 20, first quartile at 21, median at 22, third quartile at 24, and maximum at 28. Company D shows minimum at 19, first quartile at 20, median at 22.5, third quartile at 23.5, and maximum at 27. Based on the data, which company's batteries have the highest median lifespan? Company A Company B Company C Company D
Recap on median= when ranked in ordinal manner the number in middle is called median
Mode=most frequently occurring number. Be careful for the confusion
Your attachment is comprised of "box and whisker" diagrams .
Notice that the line separating the quartiles is the "median" and no other.
Ok I see
For, if the box and whisker represented mean, it would not show intern quartile range nor anything that has to do with percentile.
Note that in most cases mean is slightly below the 50th percentile because mean represents the overall aggregate of all samples
on the other hand, median represents exactly the 50th percentile
Therefore according to your question the Company B manufactures laptops with batteries that last longer than those manufactured by any other companies.
