What does denominator of z-score measure?
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
What is the most frequently occurring value of a data is a measure of?
It is the mode, which is sometimes introduced, along with the mean and median as a measure of "central tendency".
Does the value of the standard deviation depend on the value of the mean?
The standard deviation is a measure of the spread of data about the mean. Although it is essentially a measure of the spread, the fact that it is the spread ABOUT THE MEAN that is being measured means that it does depend on the value of the mean. However, the SD is not affected by a translation of the data. What that means is that if I add any fixed number to each data point, the mean will increase by that number, but the SD will be unchanged.
What is a numerical value used as a summary measure for a sample called such as a sample mean?
sampl statistics
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 does accuracy mean in math terms?
It is a measure of how close the calculated value is to the true value.
What does the standard error mean?
For a sample of data it is a measure of the spread of the observations about their mean value.
What does unequal mean?
poorly balanced or matched in quantity or value or measure
What does denominator of z-score measure?
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
What mean money as ameasure of value?

What is mean and standard deviation?
They are statistical measures. For a set of observations of some random variable the mean is a measure of central tendency: a kind of measure which tells you around what value the observations are. The standard deviation is a measure of the spread around the mean.
Is Cathode ray oscilloscopes measure peak to peak value or average or root mean square value?
