@iGreen could you help me please?
Begin with what the question is asking for.
ok 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
That's a good start :-)
thanks :) I'm not sure what to do next though :/
The question asks you to "Discuss apparent difference in the ages", can you see any?
yea it seems like the mean age of men is older (3.5238095239 years older)
Ok, that answers the "numerical argument" What about the graphical?
What does "graphical" mean?
visualizing quantititive data i believe
Correct. How do you want to visualize this data?
would i show the exponential growth in ages on a graph for both men and women?
How do you know it is exponential?
oh 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
Yes, now you are getting the idea. We need to study the "fluctuation" graphically.
Why 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 :(
ok 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
Ok, now what?
would the next step be to find the median of each set?
Sounds like a good idea :-)
Ok :) so i got Women: 37 Men: 42
You can compare that to the mean you calculated, right? icic = i see, i see
oh sorry haha :) so i get: women:41.8571428571-37=4.8571428571 men:45.380952381-42 =3.380952381
Let's return to the ordered list that you made and group together people of the same age and then make a quick histogram.
ok 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 80-21 for the interval of women and 76-32 for the interval of men?
ok 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:
Try doing it by hand first.
i 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
thats where i got the highest percentile
Good job, summarize your work and hand it in :D
ohh 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:41.8571428571-37=4.8571428571 and men:45.380952381-42 =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. "
I would only use two decimal places in your values :-)
Also, draw a neatly labeled histogram and show where on the graph the mean and median are located.
ok thank you so much!!
It is important for you to state that as we said "Note: we are not told that the data is given in chronological order"
Thanks for trying to learn :)
