... studies. A random sample of students gave a sample average of $3975, and a 95% confidence interval was found to be $3525 < µ < $4425. This interval is interpreted to mean that (a) if the study were to be repeated many times, there is a 95% probability that the true average summer earnings is not $45 ...

CHAPTER THREE: Measures of Central Tendency
... or not, the sum of the distances from the mean is generally smaller and never larger than the distances from the mode or the median. Interestingly, when a distribution is perfectly symmetrical, all three measures of tendency are equal to each other. Let's consider a CPDF. Notice the sum of X, _X, an ...

PROC DISCRETE-A Procedure for Fitting Discrete Probability Distributions
... The DISCRETE procedure fits discrete probability distributions to count data. The eight distributions available in the procedure are the Poisson, negative binomial, positive binomial, Thomas double poisson, Neyman type A, Poisson-binomial, Poisson with zeroes and the logarithmic distribution with ze ...

... We have seen that a stem-and-leaf display, a frequency distribution, or a histogram gives general impressions about where each data set is centered and how much it spreads out about its center. Now we introduce how to calculate numerical summary measures that describe more precisely both the center ...
