2. For the following raw data from scores on a test, compute the Z score. The mean for the distribution is 10 and the standard deviation is 4. Xi ZScore 14 100
VI. From T scores of 16,37. & 48 calculate the raw scores and Z scores if the mean of the sample was 25, the correlation was 0.78 and the standard deviation was 15. (5 pts total)
7. z-scores and standardized scores Is a z-score a standardized score? No Yes Consider the following distribution of scores with a mean of 50 and a standard deviation of 10. For the letters A, B, C, and D in the boxes beneath the ine labeled "z" give the z-scores corresponding to each position in the distribution. One z-score is already filled in (-1) Suppose you also want to standardize these scores to a "k" scale where the mean of k...
For a given raw score to be converted into a z score, one must know both the mean and standard deviation of the raw score distribution. True False
Use the given z-score/percentile table to answer the following question: If scores on a test are normally distributed with mean 48 and standard deviation 10, what percentage are above 62? z-score 1.1 1.2 1.3 1.4 1.5 percentile 86.43 88.49 90.32 91.92 93.32
A population of scores has a standard deviation of 5. In this population a raw score of 45 corresponds to a z score of 1.5. What is the population mean?
For each of the following questions: a. Calculate the z-scores (show your work) b. Draw the theoretical normal curve and locate the raw scores on the curve. c. Shade the area under the curve appropriate to the question or probability of interest. d. Write a complete sentence interpretation. If a distribution of scores has a mean of 75 and a standard deviation of 5 then: 1. What is the probability of a score falling between a raw score of 70...
7. z-scores and standardized scores Is a standardized score necessarily a z-score? Yes No Consider the following distribution of scores with a mean of 90 and a standard deviation of 30. For the letters A, B, C, and D in the boxes beneath the line labeled "z" give the z-scores corresponding to each position in the distribution. One z-score is already filled in (-1) Suppose you also want to standardize these scores to a "k" scale where the mean of...
