Procedure for calculating quartile deviation for raw data?
procedure: step 1: arrange your raw data in increasing order. step 2: find the Q1 is the size of the (n+1)/4th value. step 3: find the Q3 is the size of the 3(n+1)/4th value. Quartile Deviation(QD)= (Q3-Q1)/2 for example: 87 ,64,74,13,19,27,60,51,53,29,47 is the given data step 1: 13,19,27,29,47,51,53,60,64,74,87 step 2: (n+1)/4=3 therefore Q1=27 step 3: 3(n+1)/4=9 therefore Q3=6 implies QD=18.5
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.
A raw score of 6 has a z score of what?
A z-score requires the mean and standard deviation (or standard error). There is, therefore, not enough information to answer the question.
What is the z value for an IQ score of 100?
IQ is distributed normally, with a mean of 100 and a standard deviation of 15. The z-score of 100 is therefore:(value-mean)*standard deviation= (100-100)*15= 0More generally, a raw score that is equivalent to the mean of a normal distribution will always have a z-score of 0.
What is the z-score for 45.00?
There is insufficient information in the question to properly answer it. In order to compute a Z score from a raw score, you need the mean and the the standard deviation, neither of which was given. Please restate the question.

If the mean is 3 and the standard deviation is 1 the z-score associated with a raw score of 4.5?
1.50
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 standardized raw data?
Standardization of raw data is the process of making its variables proportionate to each other. In statistics, it is often achieved by subtracting the mean from values and then dividing them by their Standard Deviation.
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.
What is the ratio of raw materials to product called?
The ratio of raw materials to product is called the material yield ratio. It measures the efficiency of converting raw materials into finished products.
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.

A z-score requires the mean and standard deviation (or standard error). There is, therefore, not enough information to answer the question.
What is the z value for an IQ score of 100?
IQ is distributed normally, with a mean of 100 and a standard deviation of 15. The z-score of 100 is therefore:(value-mean)*standard deviation= (100-100)*15= 0More generally, a raw score that is equivalent to the mean of a normal distribution will always have a z-score of 0.
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.
What is the z score for 0.71?
This question cannot be answered. You need the mean and standard deviation in order to compute a Z score for a Raw score. Please restate the question.
What is the z score for a given raw score?
Let your raw score be x and M the mean and S the standard deviation. The Z score for your specific x is Z=(x-M)/S So say your score is 80 (out of 100) and the mean is 70 and the standard deviation is 10. Then the z score for your 80 is: (80-70)/10=1 If on the other hand you got a 60, then the z score would be -1.
