Question

lll e distribution are tree to vary 16) For a population with = 100, which value for the population standard deviation would cause X 120 to have the most EXTREME position in the distribution? b, =5 c.=10 d, = 20 17) Under which data transformation condition would ONLY the mean and NOT the standard deviati be altered? a when all scores are divided or multiplied by a constant b. when all scores are added or subtracted by a constant c. when all scores are divided or multiplied by another variable d. when all scores are added or subtracted by another variable 18.) With respect to notation, population variance is to population standard deviation as ao?is to b. s2 is tos c. both answers a and b d. none of the above Chapter 5: z-scores 19.) All of the following are properties of any z-score distribution EXCEPT: a the mean 0 b. the shape of the z-score distribution is the same as the shape of the raw score distribution c the standard deviation 1 d, the shape of the z-score distribution is different than the shape of the raw score distribution a they standardize a distribution, but do not provide any information about location b. they standardize a distribution and are always equal to raw scores c, they standardize a distribution and allow for comparisons between different distributions d they do not standardize a distribution, but do provide information about location 20.) Which statement best describes the concept of a z-score? 21.) Which of the following z-scores is located furthest ANTD below the mean of a distribution? az=-3.0 of 11 18 of 3825 words

Explanation / Answer

Question 16 Here,

Z = (120 - 100)/ = 20/

so as the will decrease, then Z will increase and if Z will increase than 120 will be the most extreme position of the distribution.

(a) is the correct answer.

Question 17

In addition or subtraction by a constant , mean will change not the standard deviation will change. Option b is correct.

Question 18

Option a is correct. 2 to

Question 19

Here option a and c is correct. Here b is also correct but option d is not correct. So option D is the right answer.

Question 20

z - score is a standardized distribution and allow to comparison between different distribution/.
