In applications such as reciprocal authentication and session key generation the requirement is not so much that the sequence of numbers be statistically random but that
the successive numbers of the sequence are unpredictable.
With true random sequences each number is statistically independent of other numbers in the sequence and therefore unpredictable.

Is there a statistical test to assess the difference between two ratios. I have numbers which are ratios and want to test whether there is a statistical difference between them?
You can use the z test for two proportions. The link below will do this test for you.
What is the difference between stratified and random sampling?
In a stratified sample, the sampling proportion is the same for each stratum. In a random sample it should be but, due to randomness, need not be.
What is the difference between a statistical and a non- statistical question?
a statistical is a question that has a variety of answers, but a non-statistical question has only one answer. like if i say "how old am i?" that is a non-statistical question because there is only one answer. But if I say "How old are the 6th and 7th grade students in school?" that is a statistical question because there will be various answers.
What is t Test?
t-test is the statistical test used to find the difference of mean between two groups
What statistical concept is used to explain the natural difference that exists between a sample mean and corresponding population mean?
Random error.
Statistical process control?
Explain the difference between capability and control.

What difference between Statistical Sampling and non statistical sampling?
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
What is the difference between clinical significance and statistical significance?
look for a paper being published in "The Oncologist" later this year (2008)
Is there a difference in selection of statistical tools for evaluation for non-profit organizations?
No. The primary difference between for profit and not-for-profit organizations is simply their income tax treatment by the IRS.
What statistical concept is used to explain the natural difference that exists between a sample mean and corresponding population mean?
Random error.
What is the difference between practical generalizability and statistical generalizability?
Statistical: must have random sampling, allows you to generalize to the population from which you randomly selected. Practical: do the results hold for similar individuals? allows you to generalize to similar individuals
What is the difference between SQC and SPC?
SQC or statistical quality control is concerned with using the 7-QC and 7-SUPP tools to monitor process outputs. Statistical process control, or SPC is concerned with monitoring the inputs of the process.
