- 1The most widely used measure of relative position is the _________Z score
- 2The Z score indicates the positive or negative difference between an ___________ and the _________ as measured in standard deviation units.individual score, mean
- 3Defined as the distance of a score from the mean as measured by standard deviation unitsZ-Score
- 4The mean of the z scores is any distribution is ______ and the standard deviation is ____.0, 1
- 5To convert Z scores to T scores, multiply the z scores by _____ and add _____.10, 50
- 6To transform a distribution of scores to a new standardized distribution, multiply the z score by the desired ___________ and add the desired _________.Standard deviation, mean
- 7True or false: Transforming a set of scores to standard scores does not alter the shape of the original distribution.True
- 8A measure of relative position, indicates the percentage of scores in a distribution that are equal to and fall below a given score pointPercentile rank (PR)
- 9To calculate percentile rank, arrange the scores in a frequency distribution. Determine cumulative frequency of scores below the score of interest, add one half of the frequency of scores within the interval containing the score of interest, and divide this sum by the total number of scores and multiply by _____100
- 10Two major advantages of percentile rank are:1. They have universal meaning
2. Familiar concept of 0 to 100 - 11Two major disadvantages of percentile rank are:1. Cannot be added, subtracted, multiplied or divided
2. Equal differences between percentile ranks do not represent equal differences between scores in the original distribution. - 12In a normal distribution, approximately ____ percent of the cases fall between the mean and 1 standard deviation above and below the mean34
- 13In a normal distribution, approximately ____ percent of the cases fall between the 1 and 2 standard deviations from the mean on either side14
- 14If the null is rejected, but is actually true, this is a __________Type 1 Error, probability = alpha
- 15If the null is accepted, but is actually false, this is a ___________Type 2 error, probability = beta
- 16Decision to accept or reject the null hypothesis is based on:1. Sample Size
2. Effect size
3. Interactions - 17How do you calculate a Z score?Raw score minus population mean divided by standard deviation
- 18___% fall with +-1 sd of the mean ___ % fall within +- 2 sd of the mean ___% fall within +- 3 sd of the mean68
