Hi Stephanie!

I´m studying at Agricultural Universiti of Iceland at Hvanneyri.

This morning I payed for your book and I´m out of words about it.

How com, it is possible to listen to lectures at an university, without getting the whole picture of a subject and by reading your explanation in few words and then all of a sudden, get the compleate picture?

By using your words introducing your book, “students who use it never fail, and their average grade is one or two letter grades higher than other students”.

That look logical to me, “You must be a good teacher by nature!”

Thanks for your effort!

Benedikt

Benedikt,

Thank you so much for saying this. I’m really glad it helped :)

Good luck with your studies!

Stephanie

Can you help me with missing data?

Emmanuel,

You may have some luck posting on our forums.

Stephanie

Great blog. I had some problems dealing with normal distribution on excel and thanks to your guide I solved it easily.

Thanks

Carlo

I am considering buying your book, but from the pre-view it doesn’t seem to assist with interpreting results from SPSS or to assist with interpreting results from descriptive statistics in general. I am struggling with the basics (as you can see) and need to interpret results for “Business Research” as a subject not so much only statistics. Our curriculum includes quantitative- and qualitative research, although my request to you pertains quantitative interpretation.

Will this book cover interpretation of statistics as well?

Anita,

SPSS interpretation isn’t in the book…it covers the basics for an elementary stats class and most elementary stats classes don’t use SPSS. That said, you can find some SPSS articles here.

Also, if you get stuck on something, feel free to post a comment and I’ll see if I can tackle it for an article.

Regards,

Stephanie

Hi,

Is elementary statistics the same as a basic college Introductory Statistics course? I’m actually using this to help with studying for Finals.

Thanks!

Yes, it’s exactly the same :)

what is a 5 number summary

The five number summary explained

Stephanie, I am not a math-major. 2nd, it has been 35 yrs or so since I have taken and high school or college math/algebra. No Calculus or Trig taken at all in past. My college path now requires a basic introduction to STATS and for some reason I took it online with my instructor being in California and me being in central US. Book is online as well. My problem is the book doesn’t give enough explicit detail on how to complete a statement. I will go as far as to state the book doesn’t even give a bottom line definition for a mean or what the parts are of the statement presenting a normal distribution. Here I am and in chapter 7 and next week is final time. Just by hook or crook I recalled what the “alpha” symbol is/was but did not recall how to compute anything about it. Can you help? Thank you! …..Steve

Does this help? What is an alpha level?

Hello,

I came across your website and I find it interesting and understanding to be able to solve statistical problems. I have a question here on baye’s theorem.

1- A manufacturing company employes three analytical plan for the design and development of a particular product. For cost reason, all three are made at varying time. Intact, plan 1, 2, 3 are used 30%, 20%, & 50% of the product respectively. The perfect rate for the three plans are 0.01, 0.03, 0.02 respectively. If a random product was observed and found to be defective, which plan, was must likely used and thus, responsible.

2-Police plan to enforce speed limit by using radar trap at four different locations within city limit. The radar trap at each of the locations are 40%, 30%, 20%, and 30% of the time respectively. If a person who is speeding on his way to work has probability of 0.2, 0.1, 0.5, and 0.2 respectively, of passing this locations, what is the probability that he will receive a speeding ticket?

Hello, El Farouq,

Unfortunately I don’t have the time to answer stats question in comments, but if you would like to post on our forum, one of our mods will be glad to help!

P.S. Make sure you tell them what you know/have tried :)
