What is the z score for a raw score of 70?

There is not enough information to answer your question. To determine a Z-Score, the mean and standard deviation are also required.


How do you find a z-score?

Z Score is (x-mu)/sigma. The Z-Score allows you to go to a standard normal distribution chart and to determine probabilities or numerical values.


How do you use the z-score to determine a normal curve?

If the Z-Score corresponds to the standard deviation, then the distribution is "normal", or Gaussian.


What the z-score of a person with a raw score of 20?

There is not enough information to answer your question. To determine a Z-Score, the mean and standard deviation is also required.


What z-score corresponds to this value?

There is insufficient information in the question to answer it. To determine Z score, you need raw score, mean, and standard deviation. Please restate the question.


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


Is the Z-test the same as Z-scores?

No, the Z-test is not the same as a Z-score. The Z-test is where you take the Z-score and compare it to a critical value to determine if the null hypothesis will be rejected or fail to be rejected.


What is the z score of 6.56 and how do you find it?

There is insufficient information in the question to answer it. To determine Z-Score, you need raw score, which you gave, but you also need mean and standard deviation, which you did not give. Please restate the question.


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.
