Document Summary
Normal distribution: specified b its mean and standard deviation: area is 1. If points lie close to a straight line = plot indicates that the data are normal. Distribution of a sample: all values of a single sample. Distribution of a population: all values from the population. Sampling distribution: all values the statistic can take on (and the frequency) for all samples of a give size. X bar: average of the observations in the sample: sample mean from a sample is an estimate of the mean, can take on different values if we chose another sample. Infinite # of possible values: describes relative frequency, probability of any particular event is 0 can(cid:495)t assign probability to any single value but can find probability of a range. Normal distribution: n(mu, sigma: continuous variables. Standard normal distribution: n(0,1: for a z distribution, can convert values from other distributions into the z distribution.
