If X is the mean of a score distribution, what is the mean of the mean distribution that comes from sample means taken from the score distribution? 3. If X is the standard deviation of the score distribution, and N is the sample size of the means that produce a mean distribution, then what is the standard error of the mean distribution? 4. How large does a sample size have to be to produce a mean distribution that is normal? ANSWERS 1. What theorem describes how mean distributions relate to the score distributions they are based upon? The central limit theorem 2. If X is the mean of a score distribution, what is the mean of the mean distribution that comes from sample means taken from the score distribution? X. As stated in the central limit theorem, the mean of the mean distribution is the same as the mean of the score distribution 3. If X is the standard deviation of the score distribution, and N is the sample size of the means 3....
