What is meant by the mean and standard deviation of a set of results?
Teeali
The mean is the average of the numbers in your results. For example if your results are 7, 3 and 14, then your mean is 8. Numerically, (7+3+14)/3
The standard deviation measures how widely spread the values in a data set are.

If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
Can standard deviation be greater than mean?
Standard deviation can be greater than the mean.
Is the standard deviation dependent on the mean?
Yes. Consider the definition of the standard deviation. It is the square root of the variance from the mean. As a result, it can be said that the standard deviation is dependent on the mean.
What does the standard deviation tell us about the mean?
The standard deviation tells us nothing about the mean.
The mean of A is 14 with a standard deviation of 4.2. The mean of B is 16 with a standard deviation of 4.4 Which is more dispersed?
B because the spread, in this case standard deviation, is larger.
How do you find deviation mean?
There is no such thing. Maybe your professor meant , Standard Deviation, The Mean. (2 different things.)
Which curve is more dispersed a mean 23 with standard 1 or mean 6 and standard 11?
If "standard" is meant to be standard deviation, the answer is the second.
How are Stanford-Binet intelligence scale results measured?
.The test has a mean, or average, standard score of 100 and a standard deviation of 16 (subtests have a mean of 50 and a standard deviation of 8). The standard deviation indicates how far above or below the norm the subject's score is.
What is the significance of standard deviation?
To see how wide spread the results are. If the average (mean) grade for a certain test is 60 percent and the standard deviation is 30, then about half of the students are not studying. But if the mean is 60 and the standard deviation is 5 then the teacher is doing something wrong.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What is meant by the standard deviation of a data set?
It is a measure of the spread of the data around its mean value.
What is meant by a z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
A standard normal distribution has a mean of and standard deviation of?
Mean 0, standard deviation 1.
What is the mean and standard deviation for the standard normal curve?
Mean = 0 Standard Deviation = 1
What is the difference between standard error of mean and standard deviation of means?
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
What does it mean if standard deviation was more than its mean?
It means the results (the information given) are spread out meaning the space in-between the results is quite big
How is the mean related to standard deviation?
Mean and standard deviation are not related in any way.
