100 zero What is the mean of the z-score distribution	100 Inferential Statistics What type of statistics uses sample data to answer questions about the populations?	100 False. Standard error is the amount of error between a sample statistic and its corresponding parameter. True or False. Standard error implicates that a mistake was made in the study.	100 Z = (X-μ) / σ What is the equation to find the z-score from an X-value?
200 Same What shape is the z-score distribution in relation to the x-value distribution it was taken from?	200 Probability What is the fraction or proportion of all possible outcomes?	200 The larger the sample size, the more probable the sample mean will be closer to the population mean. n ≥ 30 What is the law of large numbers, and what sample size should you try to obtain to meet this?	200 Xnew = μ + z(old score)σ What is the equation to find the new X-value from and old one?
300 Yes YesAre all z-scores comparable to each other?	300 Normal Distribution A distribution that is symmetrical, the bulk of scores are in the middle, and there is a low frequency in the tails is called what?	300 Central Limit Theorem What theory is used to specify the shape, central tendency, and variability of the distribution of sample means?	300 σM = (σ) /√ n What is the equation to find standard error of means
400 Standard Deviation Units In what units are Z score expressed in?	400 Sampling with replacement A sample process where each individuals has an equal chance of being selected, and the probability remains constants from one selection to the next, is called what?	400 Standard error of M σM Variability of a distribution of sample means is measured by the standard deviation of the sample means and is called...?	400 z = (M - μ) / σM What is the equation to find the z-score for standard error means.
500 X - μ or X - Mean The deviation score is expressed as what algebraically?	500 -0.67 & +0.67 What z-score represents the 1st and 3rd quartiles in a normal distribution? (25th percentile and 75 percentile)	500 Expected value of M What is the mean of the distribution of sample means	500 SS = ΣX^2 - ((ΣX)^2) / N What is the computational formula for finding the SS
