Understand what a binomial random variable is. Learn how to find the mean or the expected value and the standard deviation of a binomial distribution using examples. Related to this Question What is the expected
The binomial distribution formula is for any random variable X, given by; P(x:n,p) = nCxx px (1-p)n-x Or P(x:n,p) = nCxx px (q)n-x, where, n is the number of experiments, p is probability of success in a single experiment, q is probability of failure in a single ...

Since binomial variable is discrete (numbers), we can use continuous normal distribution to estimate the probability of occurring between 4.5 and 5.5. So, we calculate P(4.5 < X < 5.5) using the normal distribution. After applying the continuity correction, you will then transform the X values...

It is important to know whether you have a discrete or continuous variable when selecting a distribution to model your data. TheBinomialandPoissondistributions are popular choices for discrete data while theGaussianandLognormalare popular choices for continuous data. ...
2. Binomial Distribution When reports of it include only two alternative possible outcomes, it is construed to mean adiscrete probability distribution. This is most often the case with banking, psychology, and genetics The probability mass function of binomial distributions can be defined in terms of...
That is, we conducted binomial tests (for the binary variables) and one one-sample t-test (to compare the mean age between the two samples). This shows that our sample contains more males than the ACS sample (45.8% females versus 67.0%; p = 0.000) and is slightly younger (41.8 years...
When statistics students were taught the formula for binomial probability, the students who were taught the meaning of the variables in the formula were better able to apply their knowledge to new problems than students who were taught to only superficially manipulate the formula (Mayer Citation1975...
