what statistical analysis are possible with interval scale?
152179
An interval scale, from the following reference, is something like the Fahrenheit scale, with no absolute zero point, and a ranking, with the size of the intervals on the scale equal. Addition and subtraction of values on the scale are permitted, but not multiplication or division. \n\nAny statistical technique using addition and subtraction like the average is permitted in this case. From this definition, things like the harmonic mean are not permitted. \n\nHowever, I am less certain as to WHY multiplication and division are not permitted in this case.

The value of textual statistics is now widely acknowledged in many branches of the social sciences, reflecting the fact that there are few fields of research in which the text is not a major element for analysis.\n\nThe statistical processing may be of responses to open questions, interviews, texts and even individual itineraries. The procedures are numerous and can be adapted to different kinds of material. The aim in the present article is to give a broad overview of the various applications of these methods, ranging from the most traditional to the most recent, and focusing on both the methodology used and the results obtained.

It is based on mean and standard deviations (statistical stuff). With just the information you gave, it is impossible to tell.\nWe would need to know the mean, standard devaition, and method of calculating scale...but then again if we had all this stuuf you would be able to asnwer your own question, right?

Probabilty sampling allows you to perform stastistical analysis, such as regression, correlation and so on.  They can also be crafted to be extremely representative of the population.  You can also construct confidence intervals (for example: 54% of Americans support the bill with a margin of error of +/- 2%).  You can also use stastitical methods to prove casality or other relationships.  Non probability sampling cannot be used with stastical analysis, thus we can have no margin or error, correlation, etc.  However, given a sufficiently large sample size, non probability sampling can still be useful for getting a 'pulse' of the total population.

Matlab, Gauss, S+ and probably a lot more.\n\nIn a pinch, you can also use MS-Excel.\nDownload this pdf file from Cliff Ragsdale´s book site:\nhttp://swlearning.com/quant/ragsdale/chapter12.exe\nIt actually works better than you´d think.\n\nOr go to http://swlearning.com/quant/ragsdale/fourth_edition/ragsdale.html\npick previous edition and student resource.

Here you go!\n\nhttp://en.wikipedia.org/wiki/Likert_scale\n\nBasically it's a nice simple approach to questionnaires, giving qualitative answers a quantintative value (excellent for empirical research)\n\nHope that helps!

Do a confidence interval calculation and see if the confidence level for the data you've collected is above that required for 98%.\n\nI can show you how but given your other questions, it's clear you haven't really done any work on this yet and you're just looking to get someone to do your homework for you.\n\nLet me know if you still can't do it after you've tried a while, and I might help you out.

There is no accurate way to do this because too many variables are involved. You can do like I do though and run a series of tests and then average them.\n\nhttp://www.toast.net/

Here's a tip... why use a linear scale?  If the purpose of your plot is that you want to actually LOOK at the data, try using a log plot.\n\nInstead of:  plot(f,<quantity>);\nUse:  semilogx(f,<quantity>);\n\nIf you want better percision readout just do 'format long'.

You would look for a company that does data analysis or data mining. http://metricconsultants.com/ usually it would be some sort of consulting type of firm such as this one.

Try Chi square testing, it starts out complicated but once you understand it, it is way faster than punnett squares! You can find all kinds of stuff about it on the internet, it's a statistical analysis.

What's your problem - your in college - do your own homework (this son of a statistician is unimpressed).  If you don't know how to construct a confidence interval look at http://facweb.bhc.edu/EastCampus/leeb/ma108/06_01w/tsld032.htm\n\nGood Luck!!!

X = sample mean, U = theoretical mean, S = standard deviation, and N = number of data...\n\ni assume u know how to calculate X and S from above. \n\n.95 = P(1.96< (X-U)/(S/sqrt N) < 1.96)...solve for U..U will be in between to values, which means that you are 95% confident that U will lie in that range.

I am not sure that I follow what you are asking. Are you looking for the above items to be charted as variables on your graph?\n\nPerhaps if you post additional details in your question, it would help us.

I doubt that you can.  Use MINTAB or SPSS.
