It would depend. If my IQ had a z-score of 4 I would be thrilled because it would imply that my IQ was higher than about 99.997% of the population. Of course, on the other hand, I'd be skeptical of that because I've never given any indication of being that smart.
I suppose that's what you're getting at: a z-score this high is darned unusual.
What else can I help you with?
If mean equals 18.6 standard deviation equals 4 what is the z score?
The z score, for a value y, is (y - 18.6)/4
What does a Z-Score of 4 mean?
nobody knows
What does a z score of 4 mean?
zero you dubass
In a standard normal distribution about percent of the scores fall above a z score of 300?
A Z score of 300 is an extremely large number as the z scores very rarely fall above 4 or below -4. About 0 percent of the scores fall above a z score of 300.
What is the difference between Z-Test and The Z-score?
The Z-score is just the score. The Z-test uses the Z-score to compare to the critical value. That is then used to establish if the null hypothesis is refused.
What is z score of area 0.75?
what is the z score for 0.75
Calculate the z-score for a test score of 87 if the mean test score is 81.1 and standrd deviation is 11.06?
z score = (test score - mean score)/SD z score = (87-81.1)/11.06z score = 5.9/11.06z score = .533You can use a z-score chart to calculate the probability from there.
Can z score be possible 5?
Yes a Z score can be 5.
What does it mean if the Z score of a test is equal to 0?
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
What is the z score that correspond to P18?
Find the Z score that correspond to P25
How do you prove a z-score?
A z-score is a linear transformation. There is nothing to "prove".
Can a negative z score be greater than a positive z score?
Assume the z-score is relative to zero score. In simple terms, assume that we have 0 < z < z0, where z0 is the arbitrary value. Then, a negative z-score can be greater than a positive z-score (yes). How? Determine the probability of P(-2 < z < 0) and P(0 < z < 1). Then, by checking the z-value table, you should get: P(-2 < z < 0) ≈ 0.47725 P(0 < z < 1) ≈ 0.341345
