Stats help please?
The ages of the Oscarwinners for best actor and actress for the years 1970 through 1990 are given below:
Women:34,34,26,37,42,41,35,31,41,33,30,74,33,49,38,61,21,41,26,80,72
Men:43,40,48,48,56,38,60,32,40,42,37,76,39,55,45,35,61,33,51,32,42
Discuss apparent difference in the ages of Oscarwinning men and women. Use both a numerical and graphical argument.

Best ResponseYou've already chosen the best response.1ok thanks, i think i need to find the mean of the data sets of men and women so i got 41.8571428571 as the mean of women and 45.380952381 as the mean of men but i don't know what to do next

Best ResponseYou've already chosen the best response.1The question asks you to "Discuss apparent difference in the ages", can you see any?

Best ResponseYou've already chosen the best response.1yea it seems like the mean age of men is older (3.5238095239 years older)

Best ResponseYou've already chosen the best response.1Ok, that answers the "numerical argument" What about the graphical?

Best ResponseYou've already chosen the best response.1What does "graphical" mean?

hockeychick23

Best ResponseYou've already chosen the best response.1visualizing quantititive data i believe

Best ResponseYou've already chosen the best response.1Correct. How do you want to visualize this data?

Best ResponseYou've already chosen the best response.1would i show the exponential growth in ages on a graph for both men and women?

skullpatrol

Best ResponseYou've already chosen the best response.1How do you know it is exponential?

hockeychick23

Best ResponseYou've already chosen the best response.1oh your right sorry it isn't always exponential, looking at the data it looks like it fluctuates a lot between 1970 and 1990, I'm not quite sure how i would word that

skullpatrol

Best ResponseYou've already chosen the best response.1Yes, now you are getting the idea. We need to study the "fluctuation" graphically.

Best ResponseYou've already chosen the best response.1Why don't we start by putting the data in increasing numerical order and look for any patterns? Note: we are not told that the data is given in chronological order :(

Best ResponseYou've already chosen the best response.1ok awesome, thanks! so i got: Women:21,26,26,30,31,33,33,34,34,35,37,38,41,41,41,42,49,61,72,74,80 Men:32,32,33,35,37,38,39,40,40,42,42,43,45,48,48,51,55,56,60,61,76

Best ResponseYou've already chosen the best response.1would the next step be to find the median of each set?

Best ResponseYou've already chosen the best response.1Sounds like a good idea :)

hockeychick23

Best ResponseYou've already chosen the best response.1Ok :) so i got Women: 37 Men: 42

Best ResponseYou've already chosen the best response.1You can compare that to the mean you calculated, right? icic = i see, i see

Best ResponseYou've already chosen the best response.1oh sorry haha :) so i get: women:41.857142857137=4.8571428571 men:45.38095238142 =3.380952381

Best ResponseYou've already chosen the best response.1Let's return to the ordered list that you made and group together people of the same age and then make a quick histogram.

Best ResponseYou've already chosen the best response.1ok do i take women:21,26,26,30,31,33,33,34,34,35,37,38,41,41,41,42,49,61,72,74,80 Men:32,32,33,35,37,38,39,40,40,42,42,43,45,48,48,51,55,56,60,61,76 and subtract 8021 for the interval of women and 7632 for the interval of men?

hockeychick23

Best ResponseYou've already chosen the best response.1ok so i got 59 as the interval of women and got 44 for the interval of men. I tried to create a histogram online but i don't think it took the data correctly, it looks like this:

Best ResponseYou've already chosen the best response.1Try doing it by hand first.

hockeychick23

Best ResponseYou've already chosen the best response.1i drew the histogram of the data and it seems like the majority of women are in their 30s and the majority of men are in their 40s

Best ResponseYou've already chosen the best response.1thats where i got the highest percentile

Best ResponseYou've already chosen the best response.1ohh wow thanks! so i can just say "the numerical argument is: the mean of the data sets of men and women so i got 41.8571428571 as the mean of women and 45.380952381 as the mean of men and the mean age of men is older (3.5238095239 years older) graphical argument: this is visualizing quantitative data;the data fluctuates between 1970 and 1990 the median of women is 37 and median of men is 42. Comparing this to the mean I get: women:41.857142857137=4.8571428571 and men:45.38095238142 =3.380952381. 59 is the interval of women and 44 is the interval for men. " Graphically: "The majority of women are in their 30s and the majority of men are in their 40s, this is where i get the highest percentile. "

Best ResponseYou've already chosen the best response.1I would only use two decimal places in your values :)

Best ResponseYou've already chosen the best response.1Also, draw a neatly labeled histogram and show where on the graph the mean and median are located.
