Best ResponseYou've already chosen the best response.4well then I believe that answer will be given by this then \[(55+150+325+510+780+990)(40+150+300+500+800+1000)\]

Best ResponseYou've already chosen the best response.4the median is the number in the middle of the data we have an even amount amount of data points so we will need to look at the two middle numbers and find the average of two middle numbers to find the median

Best ResponseYou've already chosen the best response.4the average of n numbers is the sum of those n numbers divided by the number of numbers n

freckles

Best ResponseYou've already chosen the best response.4that is to find the average of two numbers, 86 and 87 you add them and divide by the number of numbers, 2

freckles

Best ResponseYou've already chosen the best response.4are you good with the median?

freckles

Best ResponseYou've already chosen the best response.4do you need help adding 86 and 87 and dividing that result by 2?

freckles

Best ResponseYou've already chosen the best response.4I will give you a hint what number is midway between 86 and 87

freckles

Best ResponseYou've already chosen the best response.4if you don't know then just do (86+87)/2

Best ResponseYou've already chosen the best response.4anyways after we find the median we will find the "median" of the upper data and find the "median" of the lower data I put median in quotation marks since we are actually finding the upper quartile and lower quartile number respectively

freckles

Best ResponseYou've already chosen the best response.4right this is correctly shown as the median on the graph

freckles

Best ResponseYou've already chosen the best response.4so moving on to upper quartile number

Best ResponseYou've already chosen the best response.490,92,93,93,94 what number is the middle number here

freckles

Best ResponseYou've already chosen the best response.4right that number is the upper quartile number and yes 93 is in the middle there because you have exactly two entries to the right and left of it and we can end the discussion here since that is not shown in the graph correctly we need to spot the middle number in the lower data points 74,74,83,83,83 83 is the lower quartile number since it is the middle number of the lower points you have exactly two entries to right and left of it that is shown correctly in the graph
