Mean and Standard Deviation of Binomial Distribution Binomial distribution comes from a series of Bernoulli trials (an experiment with two outcomes, "suceess" and "failure", where we translate "success" as the number 1, and "failure" as zero). The basic question: How many successes can we ...
If one measures the fraction of outcomes of one type that occur in a certain number of tosses, then the mean of the distribution equals the probability of that outcome, and its standard deviation varies inversely as the square-root of the number of trials conducted. Thus, the larger the ...
Standard Deviation [mp(1 – p)]12 Additional properties are 1. For p = 0.5, the binomial distribution shape looks normal (bell-shaped). 2. For p < 0.5, the distribution curve is skewed right, and the skewness increases as p decreases. 3. For p > 0.5, the distribution curve is skewe...
当这三个条件都满足时,你就可以用binomial distribution.2. 当题目告诉你population standard deviation时,你用 Z test当题目没有告诉你population standard deviation,只告诉你sample standard deviation,你用T test不知道你什么时候考试,在中国学Ap statitics是有些麻烦,不过还是要加油,题目不要做太多,真题就只有三套...

then the binomial distribution becomes a discrete Poisson distribution. If n is sufficiently large without any constraint on p, then the binomial normal distribution approximation may be used. The binomial mean and standard deviation become the normal distribution’s parameters and a correction for cont...
