Statistics Tutor - Are you Interested?

I'm feeling downright menopausal. I remember using my slide rule for the linear modeling/analysis of variance course in the late 1960s.

Time flies when you're having fun.

Happy New Year, all.

The dissertation's done. It will go to my committee in a few days for review. Whether or not the results will find their way to other forms of publication will be seen.

 

Rich - that is great. I hope you do publish your work elsewhere. It would seem that the subject would be a popular choice by journal editorial boards. Good luck at the committee level.

All the best,
John

 

You may already own the right software application....

This stuff can be done in Microsoft's Excel application software that you may already own. I can do this in my Excel versions 4 and 5.

Wow, the book just arrived in the mail and it is so easy to read!!! It has already answered my question about the chi square formula!!!

However, I do have one more question for you. My statistics class has long since ended, but the professor told me to use the "correlation statistic (r)" for the following scenario. Can you tell me what section it is in in the book that you recommended to me i.e. section 6.1 or whatever.

Here is the scenario:

• I have obtained the aggregate number of juvenile arrests for my county (to include the municipalities) for the last five years. It is broken down by month. It is around 8800 arrests.
  
• I am currently trying to obtain the aggregate number of "habitual truants" for my county (and the inclusive municipalities) for the last five years and also broken down by month. A habitual truant is a student who has missed at least 15 days in a 90 day period.
  
• I want to see if there is a monthly correlation between the number of juvenile arrests and habitual truancies. For example, as habitual truancies rose or fell, did the juvenile arrest rate rise or fall?
  
• I also want to see if there is an annual correlation between the number of juvenile arrests and habitual truances for the last five years.

Which section of the book would cover this type of forumula? Any input is greatly appreciated.

Pray tell?

These aren't "trade secrets." I'm not worried about giving up a good idea because I have lots more.

 

For example, we might have the following monthly numbers:

• Month 1
  300 habitual truants
  140 arrests
  
• Month 2
  290 habitual truants
  150 arrests
  
• etc...

For the annual talley going back five years, I presume we'll use the same formula.

What section of the book covers it?

 

You are spending too much money and too much time........as was mentioned above, check first on the legality of having outside help. If allowed, call the stats or biostats department of a local university and ask for a student who is willing to do the number crunching for you. The numbers in my dissertation were collected and summarized by me and turned over to a biomed PhD student who processed them and explained the meaning for a sum of $200.00 bucks. All the of the books mentioned above are good, read most of them during my MBA and MA in Counseling, SPSS (student copy) is well worth the money if you have to do the numbers, and Excel may do all you need. So, look at the options before you spend all that time and money. Good Luck. And remember "There are liars, damn liars and statiticians." And a really good styx person can used the same data to prove either point.

 

Remember, there are liars, damn liars & statiticians

Good idea. Thanks.

I purchased a book called "Computational Handbook of Statistics" which is user friendly, so all I need to know now is which statistical formula to use.

If I know which formula to use, then I don't mind sitting down on a Sunday and computing it all out. It shouldn't take more than a few hours.

 

I assume you're attempting to correlate the two. For what? Are you trying to determine if a change in one results in a change in the other? Or that there is a common core action agent causing these to move one way and another?

This is elementary statistics contained in any textbook. Try "Statistics Without Tears" by Derek Rowntree.

 

Yes, that is correct.

I am an elementary fellow.

Very elementary.
