What does a negative z value mean?
Negative z value means that the raw dat is below the mean, if z value is positive it means that the raw data is above the mean.
IQ test scores are normally distributed with a mean of 100 and a standard deviation of 15 An individual's IQ score is found to be 110 Find the z-score corresponding to this value?
mean= 100 standard deviation= 15 value or x or n = 110 the formula to find the z-value = (value - mean)/standard deviation so, z = 110-100/15 = .6666666 = .6667
What is the median of 1 number only?
Your single number is your only information of the median value of the population, so the median value is the same as your single number. It is also the mode and mean of your sample.
What is the of z-score -1.0?
A z score is a value that is used to indicate the distance of a certain number from the mean of a normally distributed data set. A z score of -1.0 means that the number is one standard deviation below the mean. A z score of +1.0 means that the number is one standard deviation above the mean. Z scores normally range from -4.0 to +4.0. Hope this helps! =)
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.
The z value corresponding to a number below the mean is always negative?
Yes.
If a data point has a corresponding score of -1.5 then it is one and a half standard deviations above the mean value.?
If you are talking about the z-value of a point on the normal curve, then no, it is 1.5 standard deviations BELOW the mean.
Does a serial number below 900 mean anything as to the value of a 41 byf luger?
no, just means gun made early 1941 (based on serial number)
What does a negative z-score mean?
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
What does the maths term median mean?
It is the value of all numbers in the range in which there are as many values above it as there are below it. For example for the ordered values 1,3,7,9,10,12,15,19,21 the median value is 10. It is not he same as the mean, or average, which is the sum divided by the number of values.
What does it mean to have a sharp slope?
If the slope has a large number, the corresponding line is also said to be STEEP.
What does a negative z value mean?
Negative z value means that the raw dat is below the mean, if z value is positive it means that the raw data is above the mean.
What is the mean value of 2641258900654?
The mean value of any one number is itself. So the answer is 2641258900654.
What does the absolute value of a number mean?
The absolute value of a number is the distance that number is from zero.A more accurate description is to say the absolute value of a number is the value of the number regardless of its "+" or "-" sign, which is also known technically as its "polarity".Further notesThe "value" of any particular number means the quantity or amount of some things which that number represents.Just a few examples of some values are shown in bold below:5 apples for which the absolute value is 5-12 volts for which the absolute value is 121000 houses for which the absolute value is 1000-273 oC for which the absolute value is 2730.1 miles for which the absolute value is 0.1
