Best ResponseYou've already chosen the best response.0No. i don't but the z score is 1.33 so I am guessing that the z score is negative but i am not sure

Best ResponseYou've already chosen the best response.0I always thought you could tell the if the zscore was positive or negative based on whether or not it had a negative sign in front of it...

Best ResponseYou've already chosen the best response.0I think that Since Z = (scoremean)/standard deviation, scores below the mean will have a negative value, and those above the mean will have a positive value.

Best ResponseYou've already chosen the best response.0weren't you told that the zscore is 1.33 > 0 (??)

Best ResponseYou've already chosen the best response.0I was told that the z score was 1.33 which is 1.33 sd from the mean

Best ResponseYou've already chosen the best response.0Thanks. I am still not sure if I am correct or not that my z score is negative value.

Best ResponseYou've already chosen the best response.0I think it's negative. But I don't know what the mean is. I think that the 1.33 is below the mean in this case thought. REally, I just don't know...

Best ResponseYou've already chosen the best response.0Thanks Tim. I agree. I believe that the 1.33 is below the mean of 17 thus making it a negative z score value, but I am not positive.

Best ResponseYou've already chosen the best response.0? I'm not sure I agree. If you're told that the z value is 1.33, then the z value is 1.33 > 0. If the z value was negative then the z value would have been 1.33.

Best ResponseYou've already chosen the best response.0That's what I thought at first. I was just getting confused though.

Best ResponseYou've already chosen the best response.0What I was thinking Broken Fixer was. Since Z = (scoremean)/standard deviation, scores below the mean will have a negative value, and those above the mean will have a positive value. The mean is 17 and the z score is 1.33 the z value would be negative. The score was 21 and the mean was 17 standard deviation would be 3

Best ResponseYou've already chosen the best response.0when z = +1.33, you have a raw score that is 1.33 standard devs above the mean of the data

Best ResponseYou've already chosen the best response.0x = 21, sigma = 3, mu = 17 will give you z = +1.33 > 0 yes

Best ResponseYou've already chosen the best response.0The raw score is 21 you would subtract the mean of 17 from 21 and divide theat result (4) by the standard deviation of 3. The zscore of 1.33 tell

Best ResponseYou've already chosen the best response.0"z value" is a synonym for "z" is a synonym for "z score" and in this case it is 1.33 >0, because x is above the mean.

Best ResponseYou've already chosen the best response.0so are you saying that the z score in this case is positive?

IsTim

Best ResponseYou've already chosen the best response.0I agree. I don't remember why I said negative. I know you disagree with this, and probably feel unsatisfied. Try looking through your textbook, or ask another source.

Best ResponseYou've already chosen the best response.0No I aactually get it now and agree. Aftere reading the book again and reading what you and Broken Fixer said, I agree that it is infact a positive value. Thanks for helping me through this!
