What Is Negative Z Score Mean Negative z score The individual value is less than the mean A z score of 0 The individual value is equal to the mean The larger the absolute value of the z score the further away an individual value lies from the mean The following example shows how to calculate and interpret z scores
A z score is a statistical measure that describes the position of a raw score in terms of its distance from the mean measured in standard deviation units A positive z score indicates that the value lies above the mean while a negative When the z score is negative the raw score is lower than the mean average For example a z score of 3 means that the information is three standard deviations below the average What does a z score mean A z score means the number of standard deviations a value is from the mean

Yes a z score can be negative In a case in which the z score comes out as a negative value it means that the data point in question is below the average for the given dataset mean This is part of life for the z score and is to be expected based on how data points are distributed around the mean in a normal distribution Negative Z Score A negative Z score indicates that the data point is below the mean For example a Z score of 2 means the data point is 2 standard deviations below the mean
A negative z score indicates that the raw score is lower than the mean average For example if the z score is equal to 3 it means that it is three standard deviations below the mean What is a Z Score The z score describes how many standard deviations a raw score is above the mean Negative z scores indicate a position below the mean For example a z score of 2 means two standard deviations above the mean and a z score of 1 means one standard deviation below the mean

What is a Negative Z Score Table A negative z score has a value that is below or to the left of the mean of the standard normal distribution Thus a negative Z table displays Z values less than zero What is a Positive Z Score Table A positive z score has a value that is above or to the right of the mean of the standard normal distribution A negative Z score indicates that the value is below left of the mean A Z score of 0 indicates that the value is equal to the mean There are a few different formulas for calculating a Z score Given that the population mean and standard deviation are known a Z score can be calculated using the following formula
A negative z score means the data value is smaller than the mean If a data value has a z score of 3 1 then this data value is 3 1 standard deviations smaller than the mean A negative z score is an indicator of a raw score that is lower than the mean As explained below a z score that is neither positive nor negative but equal to zero is an indicator that the particular raw score happens to be equal to the value of the mean
