Graphing Curves From Descriptive Statistics |
Graphing Curves From Descriptive Statistics - Excel |
|
For example:
mean: 8.147
standard deviation: 0.142
Assuming a normal curve, I am told that I can graph this, but I don't believe it's possible with Excel.
That is, I can do the following: generate a random number set with a normal distribution, then create a histogram.
What I'd like to do is create a continuous line curve of the kind you see in textbooks, to illustrate rejection regions and critical values, etc. I suspect I'll need to look into some other software package or browser-based statistical application but before I say good bye to Excel on this I thought I'd check here.
Cheers

(note - in anticipation of a statistics class next year where there will be a lot of hypothesis testing for the first section. I sort of blew it in the first half of the course by just drawing all my graphs by hand, much to my prof's "delight").

I'm really hoping someone can help me with this...
I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....
Can someone please offer a suggestion for how to do this? I would really appreciate it.
Also, would it be possible to link data from other sheets in the workbook into one single chart?
I have 3 variables that I'm charting. I have one on the primary axis and it's values are in the billions. I have one on the secondary axis and it's a percentage. I need to display a 3rd who's value is in the millions. If I put it on the primary axis, you cannot see modest changes.
Is there a tricky way to get all three on one graph? I know I could split on two graphs, so that's my backup plan.
Thanks,
Dave
Say I had a line graph for 4 years and I wanted it to be a solid line for the first three and a dashed line for the last one, is that possible?
Many thanks for your help
Firstly i haven't used excel to a great extent since my college days. So i'm having to re-learn 99.9% of everything i once new...
I am volunteering for a non profit organization and trying to create a reservation system for the rooms that they have - kind of like hotel software, but in excel (i did a similiar thing in college but for plane seats)
Please find it attached.
What i need it to do:
Copy all of the info from the main page to the guest lit (a new row each time).
From the guest list to the Gannt chart - i did a few tutorials on dynamic gantt charts using conditional formatting but cannot get them to work when based on data on a different worksheet.
Finaly is there a way to check for availabilty on any given date?
if just someone could point me in the right direction, i would be appreciate it so much words can't express!!!
Best Regards,
Jamie
P.S for the calender drop down on the main page, i'm using 'microsoft time & date picker 6.0)

I'm thinking there has to be a more automated way to discover the best unique key of existing fields and their data. I thought I'd post this as a challenge because I don't know the "right" (or better) answer.
Anyone have any ideas?
Is there a way to have the Min and Max values adjusted dynamically for the Scale of the values being displayed ??
I know that I can use named ranges to display various sections of data -- month by month, or quarter by quarter, for example.
But when the value of these ranges vary greatly from section to section I end of having to manually go and adjust the Min and Max values of the chart scale.
For example, if I was looking at a graph of the S&P 500's prices last November, a Min and Max range of 750 to 1200 would be fine. But if I had a dynamic range established and scrolled over to view the S&P 500's prices for this past February, I would need a Min and Max range of around 650 to 850.
Is there a way to have these Min & Max values adjust automatically depending on the values being displayed ??
Thanks

Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

I have a dillemma here,
I have to create a schedule which incorporates lunches automatically (either half hour or 1-hour lunches, depending on the circumstances).
The schedule only has time in and time out, but I need excel to automatically deduct the lunch break depending on the circumstance:
If you worked less than 6 hours = no lunch
If you worked more than 6 hours, but less than or equal to 8 hours = 0.5 hour lunch
If you worked more than 8 hours = 1 hour lunch
I am assuming the formula for this will be really long, but I have looked online everywhere and have not found ONE formula for it. I can't put lunch breaks seperately, so all I have to work with is Time in/out.
Also, I wouldn't be able to use military time, so I don't know how excel can assume that time in is in the morning, and time out is in teh evening and/or half-day.
If someone can help it would be greatlyyyy appreciated
My question is:
Is there a way to check for duplicates, and then automatically add numbers to the duplicate values to make them unique? If so, how can this be done?
So that you will have this:
JohnSmith
JohnSmith2
JohnSmith3
JaneDoe
JaneDoe2
JohnAdams
JohnAdams2
JohnAdams3
JohnAdams4
I think I have done a good job in illustrating what I would like to be able to do, but if there is still something that is unclear, I will post whatever clarification is needed.
Thank you in advance for your help!!
I am trying to make excel automatically add a leading zero to values which are 5 digits long;
i.e. number input is 15185, then excel automatically changes it to 015185.
If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.
Is there any way of writing a small macro to sort this out.
The numbers would be input into range B16:223.
Many thanks,
Andy
But I did so in a beta file (test file). The real file has become so big (103MB!) that Excel cannot even open it anymore! The file contains archive info that we do not have anywhere else.
Is there anyway then to open the file or to reduce its size without opening it (through magics...)? I just honestly don't know how to retrieve that info before deleting that file.
Thank you very much for your help.
I'd like to do this in Excel, but I can't figure out how to have a randomly generating non-repeating macro with text values in cells.
So right now I have a column of 8 values and need matrix of 7 columns by 8 rows next to it.
I've found this thread that has one for numbers, but I can't figure out how to do it for text values...

Thanks all!
so I thought I would try again.
Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.
Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."
Thanks very much.
I've been having a strange problem lately. I have a fairly lengthy macro that works perfectly most of the time. Occasionally it will run as expected but as soon as the macro ends, excel becomes unresponsive to mouse-clicks. When I click anywhere (trying to select a cell, or an excel menu item...clicking anywhere in excel) I'll get the a 'ding' system sound and nothing will happen. BUT, if I use the keyboard arrow keys, I can see that the active cell selection moves accordingly. Then it gets really strange - when I have a cell highlighted and press any key to input text, it gets duplicated. So if I press "s' it will input "ss" into the cell, and then when I press enter it will auto-move to the next cell down, but nothing ends up getting saved into the previous cell.
I don't understand what's going on at all. I can't think of anything in my macro that would have these kinds of effects. I've made sure that screenupdating is turned back on at the end of every procedure. If I go into the VBE, I can manually run procedures and they all work fine. The only way I've been able to get back to normal is by force closing excel altogether and re-opening. Any ideas?
______________________
Still having trouble, and the same thing is happening with this workbook on two different computers, so I don't think it's a hardware, or OS specific issue. When it gets locked up like this, I can still do anything in the VBE (edits cells, run macros, etc.) with no problems. If I'm in the excel window, I can click alt on the keyboard and the shortcut keys for the menu come up, but I can't go deeper than that by clicking the letter shortcuts, they do nothing. If I use the delete key to delete the contents of a cell, then it gets deleted. But if I type anything else (numbers, letters, or symbols) then it types 2 instances of the key every time, yet when I hit enter, nothing changes in the cell. I also can't really bring focus to the excel window if something else (ie. the VBE) is on top of it, clicking into the excel window just gives the little system 'ding' sound and nothing happens.
If I hit the save button in the VBE (since I can't click anything in the excel window), then it seems to snap out of it and go back to normal. I tried searching for anything simmilar to this and can't find anything...
Any help would be much appreciated. This is driving me nuts!
Random question i have a large Excel Workbook (which is protected) and has over five sheets on it - however one sheet has randomly decided not to scroll... yes i know sounds random! If i use the cursor and down arrows the selection just disappears off the screen.
The page will scroll if i filter by one field, but not if i select (All) for all filters.
All other worksheets scroll fine.
Any suggestions?
Thanks in advance.
Cheers Kaite
Thanks!
the top half of my spreadsheet are assumptions, formatted with the corrects widths needed, but then below I have calculations and such that I do not want the same widths for. how can I lock in the top part so I can decrease the column widths for the bottom half of my spreadsheet?
hope this makes sense.
