i cant draw a graph for my question i have to describe it

I haven't got enough time to help you with all this Remember the median is the middle value mean = sum of all the values divided by 7

and the range = highest value - lowest
Howard-Wolowitz
  • Howard-Wolowitz
so would you suggest I put that all values are the same?
Howard-Wolowitz
  • Howard-Wolowitz
guys, each time i do it i draw graphs but i wouldnt know how to put them into the words for the answer
welshfella
  • welshfella
the median is the same for all three - check out the middle value
Howard-Wolowitz
  • Howard-Wolowitz
i see its 11
welshfella
  • welshfella
right Have have you worked out each of the mean's?
Howard-Wolowitz
  • Howard-Wolowitz
no i was trying to figure out what standard deviation was
Howard-Wolowitz
  • Howard-Wolowitz
i do it now
Howard-Wolowitz
  • Howard-Wolowitz
A: 11 mean B: 11 mean C:11 mean
Howard-Wolowitz
  • Howard-Wolowitz
So, thats something thats similar

  • Howard-Wolowitz
oh, and the median is the same for all three
welshfella
  • welshfella
right the above histogram is for the list C and gives an idea of the distribution of the numbers
welshfella
  • welshfella
yes mean and median are the same
welshfella
  • welshfella
and also the range is the same 17 - 5 = 12 in each case
Howard-Wolowitz
  • Howard-Wolowitz
oh i missed that
welshfella
  • welshfella
you can draw similar histograms for A and B to show the difference in distribution of the values
welshfella
  • welshfella
the standard deviation is a bit more complicated do you know how to work that out? its values gives an idea of the spread of data within the data set.
Howard-Wolowitz
  • Howard-Wolowitz
For the standard deviation of "A" I got 4.3
Howard-Wolowitz
  • Howard-Wolowitz
For the standard deviation for "B" I got 5
Howard-Wolowitz
  • Howard-Wolowitz
For the standard deviation for "C" I got 6
welshfella
  • welshfella
yes that figures the spread is not that much different but because of the 3 5's and 3 17's in C it will be greater that A or B.
Howard-Wolowitz
  • Howard-Wolowitz
So, my final answer answer is gonna be: For all three, mean, median and range are the same but standard deviation is different in all three.
welshfella
  • welshfella
yea
welshfella
  • welshfella
- well say std dev for C is greater than B and B greater than A.
