1. Use the website www.shodor.org/interactivate/activities/histogram/index.html to complete this assignment. Look at the dataset for "Gas Mileage for Year 2000 Cars." Set the bin width to six and describe the distribution

I don't understand how to do this, at all. @jim_thompson5910

`bin width` means the width of each histogram bar basically it's another way of saying `interval size`

set "interval size" to 6 and hit the "update interval" button
xxImHisGirlxx
  • xxImHisGirlxx
so, it changed it to 6.000, is that right?
jim_thompson5910
  • jim_thompson5910
yeah I have that too
jim_thompson5910
  • jim_thompson5910
you should see a lot of thin bars

Now what is it asking me to describe?
jim_thompson5910
  • jim_thompson5910
basically they want the overall shape of the distribution
jim_thompson5910
  • jim_thompson5910
is it symmetrical? skewed left? skewed right?
xxImHisGirlxx
  • xxImHisGirlxx
What is the distribution?
jim_thompson5910
  • jim_thompson5910
the distribution is the collection of numbers visually it's shown as a histogram
xxImHisGirlxx
  • xxImHisGirlxx
and is it skewed left?
jim_thompson5910
  • jim_thompson5910
well it turns out that the median is 496 and the mean is 507.1734104046 I pasted the numbers (from that text box) into OpenOffice Calc. It's a free spreadsheet program. I used the AVERAGE and MEDIAN functions to find the mean and median. Anyways, because the mean is larger than the median, we have a distribution that is skewed right. Notice we have outliers on the right side. These values pull the mean to the right skewing it.

What about this one? 2. Use the website www.shodor.org/interactivate/activities/histogram/index.html to complete this assignment. Many statisticians suggest about seven bins for a histogram. Try this method out on the datasets for "NBA Team Payrolls" and "Horsepower of Cars." What bin width did you choose for each?
jim_thompson5910
  • jim_thompson5910
hmm I'm not sure. It seems like any whole number would work as long as it's not too small
jim_thompson5910
  • jim_thompson5910
15 or 20 seems to work

Use the website www.shodor.org/interactivate/activities/histogram/index.html to complete this assignment. Many statisticians suggest about seven bins for a histogram. Try this method out on the datasets for "NBA Team Payrolls" and "Horsepower of Cars." Enter in the dataset {1, 3, 4, 5, 6, 7, 9}. Can you choose a bin width for which the data appears skewed right? If so, what is that bin width? Help me with this one?

alter the "interval size" and try to make the distribution skewed right. Basically try to have the majority of the distribution on the left side with outliers on the right side
xxImHisGirlxx
  • xxImHisGirlxx
I'm so lost, I really don't understand how to do any of this. :(
xxImHisGirlxx
  • xxImHisGirlxx
what does the dataset numbers mean that it gives me?
xxImHisGirlxx
  • xxImHisGirlxx
For "NBA team payrolls" would it be 1? I don't know what I'm doing.
jim_thompson5910
  • jim_thompson5910
they want you to type in 1, 3, 4, 5, 6, 7, 9 but do it in a column of numbers
jim_thompson5910
  • jim_thompson5910
to be honest, these problems are a bit strange and vague. There is no set rule for what a proper bin size is. This is one reason (of many) why statistics is misleading and can be used to alter the truth in a way
xxImHisGirlxx
  • xxImHisGirlxx
So type in the number in the interval box, but separately?
jim_thompson5910
  • jim_thompson5910
no, in the text box below where you see the big column of numbers
jim_thompson5910
  • jim_thompson5910
where it says "enter data, 1# per line"
xxImHisGirlxx
  • xxImHisGirlxx
So like this? 9 7 6 5 4 3 2 1
xxImHisGirlxx
  • xxImHisGirlxx
or, this, 12345679?
jim_thompson5910
  • jim_thompson5910
yes one big column like you had it the first way
xxImHisGirlxx
  • xxImHisGirlxx
then click update data?
jim_thompson5910
  • jim_thompson5910
correct
xxImHisGirlxx
  • xxImHisGirlxx
and then find which one is skewed right?
jim_thompson5910
  • jim_thompson5910
yes
jim_thompson5910
  • jim_thompson5910
by adjusting the interval size
xxImHisGirlxx
  • xxImHisGirlxx
okay so, I put them numbers in the big column and then play with the interval size until its a skewed right?
jim_thompson5910
  • jim_thompson5910
correct
xxImHisGirlxx
  • xxImHisGirlxx
is the 2.773 look right?
xxImHisGirlxx
  • xxImHisGirlxx
on horsepower of cars
jim_thompson5910
  • jim_thompson5910
4 looks like a good value to make it skewed right a bit
xxImHisGirlxx
  • xxImHisGirlxx
what about for the nba team playoffs ?
xxImHisGirlxx
  • xxImHisGirlxx
I say 3
jim_thompson5910
  • jim_thompson5910
3 works
xxImHisGirlxx
  • xxImHisGirlxx
Thank you so much!!!
jim_thompson5910
  • jim_thompson5910
sure thing
