Best ResponseYou've already chosen the best response.11. 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

Best ResponseYou've already chosen the best response.1I don't understand how to do this, at all. @jim_thompson5910

Best ResponseYou've already chosen the best response.1`bin width` means the width of each histogram bar basically it's another way of saying `interval size`

Best ResponseYou've already chosen the best response.1set "interval size" to 6 and hit the "update interval" button

Best ResponseYou've already chosen the best response.1so, it changed it to 6.000, is that right?

Best ResponseYou've already chosen the best response.1Now what is it asking me to describe?

jim_thompson5910

Best ResponseYou've already chosen the best response.1basically they want the overall shape of the distribution

Best ResponseYou've already chosen the best response.1is it symmetrical? skewed left? skewed right?

Best ResponseYou've already chosen the best response.1What is the distribution?

jim_thompson5910

Best ResponseYou've already chosen the best response.1the distribution is the collection of numbers visually it's shown as a histogram

Best ResponseYou've already chosen the best response.1and is it skewed left?

Best ResponseYou've already chosen the best response.1well 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.

Best ResponseYou've already chosen the best response.1What 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?

Best ResponseYou've already chosen the best response.1hmm I'm not sure. It seems like any whole number would work as long as it's not too small

Best ResponseYou've already chosen the best response.115 or 20 seems to work

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?

Best ResponseYou've already chosen the best response.1alter 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

Best ResponseYou've already chosen the best response.1I'm so lost, I really don't understand how to do any of this. :(

Best ResponseYou've already chosen the best response.1For "NBA team payrolls" would it be 1? I don't know what I'm doing.

Best ResponseYou've already chosen the best response.1they want you to type in 1, 3, 4, 5, 6, 7, 9 but do it in a column of numbers

Best ResponseYou've already chosen the best response.1to 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

Best ResponseYou've already chosen the best response.1So type in the number in the interval box, but separately?

jim_thompson5910

Best ResponseYou've already chosen the best response.1no, in the text box below where you see the big column of numbers

jim_thompson5910

Best ResponseYou've already chosen the best response.1where it says "enter data, 1# per line"

Best ResponseYou've already chosen the best response.1So like this? 9 7 6 5 4 3 2 1

Best ResponseYou've already chosen the best response.1yes one big column like you had it the first way

Best ResponseYou've already chosen the best response.1then click update data?

xxImHisGirlxx

Best ResponseYou've already chosen the best response.1and then find which one is skewed right?

jim_thompson5910

Best ResponseYou've already chosen the best response.1by adjusting the interval size

xxImHisGirlxx

Best ResponseYou've already chosen the best response.1okay so, I put them numbers in the big column and then play with the interval size until its a skewed right?

Best ResponseYou've already chosen the best response.14 looks like a good value to make it skewed right a bit
