Why parameter should not change?
In statistics the parameters of the distributions of populations are the fundamental values of interest. In a way the randomness just gets in the way of learning about the parameters. They are considered constant because they define or characterise the distributions of populations.
What does probalility distribution mean?
In parametric statistical analysis we always have some probability distributions such as Normal, Binomial, Poisson uniform etc.In statistics we always work with data. So Probability distribution means "from which distribution the data are?
Why normal distribution is better than other distributions?
It may not be better, but there is a lot of information on the normal distribution. It is one of the most widely used in statistics.
Why you prefer normal distribution over other distributions in statistics?
we prefer normal distribution over other distribution in statistics because most of the data around us is continuous. So, for continuous data normal distribution is used.
What do the variance and the standard deviation measure?
They are measures of the spread of distributions about their mean.
Why you prefer normal distribution over other distribution in statistics?
Why we prefer Normal Distribution over the other distributions in Statistics
Can you get Linux XP for free?
There is no such thing as "Linux XP". If you're referring to Windows XP, then the answer is no. As far as Linux distributions, for the majority of distributions, they are free (as in freedom) and free-of-charge.
What has the author Osama Abdelaziz Hussein written?
Osama Abdelaziz Hussein has written: 'Robust estimation for the mean of skewed distributions' -- subject(s): Robust statistics, Estimation theory
Is Linux a free operating system?
Most Linux distributions are free
Who are responsible for development of statistics?
While statistics have been around since 1749, Johnson and Kotz are credited with the development of statistics. In the 1970s, they published a four-volume compendium on statistical distributions which has proven to be invaluable even today.
Is the sum of deviations from the mean equal to zero in symmetrical distributions?
It is equal to zero in ALL distributions.
Why some Linux distributions not free?
blah blah blah
What are advantages of inferential statistics?
They give estimates of unknown parameters which can then be used to make predictions based on distributions which are better known.

What are sampling distributions used for?
Sampling distribution are used to: a) Estimate the number of samples or surveys to make to obtain a specified confidence in a particular statistic. b) Determine the confidence interval and the margin of error of a particular statistic. c) Conduct a hypothesis test on a particular statistic. I note that common statistics are mean and variance. However, there are sampling distributions for many statistics, including proportion and coeficient of correlation. Hypothesis testing can be one tail or two tail, and there are different approaches.
What are examples of statistics?
Examples of statistics include averages (such as mean, median, mode), dispersion (such as range, variance, standard deviation), probability distributions, correlation coefficients, and hypothesis testing.
