Non-negative means either zero or positive.
No. The absolute value is non-negative but, to be pedantic, that does not mean positive. The absolute value of 0 is 0 which is NOT positive.
No, an absolute value must be non-negative.
The absolute value of a number measures its distance from zero on the number line, regardless of direction. Since distance cannot be negative, the absolute value is always non-negative. For any real number ( a ), the statement ( a = -a ) only holds true if ( a = 0 ); otherwise, the absolute value is defined as ( |a| = a ) for non-negative ( a ), or ( |a| = -a ) for negative ( a ), ensuring it remains non-negative.
No. That is only true for non-negative numbers. The value of a negative number, such as -3 , is negative 3. But its absolute value is 3.
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
Yes, absolute value is a number that is a whole number and it is non-negative.
No. The absolute value is non-negative but, to be pedantic, that does not mean positive. The absolute value of 0 is 0 which is NOT positive.
No, an absolute value must be non-negative.
NO, absolute value is always non-negative.
No. That is only true for non-negative numbers. The value of a negative number, such as -3 , is negative 3. But its absolute value is 3.
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.
A negative z-score indicates that the observed value (or statistic) was below the mean. In non-directional tests, a negative z-score is just as likely as a positive one.
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.
It means that the number is zero or more, just not less than zero. "Positive" means more than zero. "Non-negative" means either zero or else more than zero.
Absolute value is always positive. * * * * * The pedantic answer is "non-negative".
non-negative would be any number that is greater than or equal to zero.
A positive value is a value that is greater than zero. A negative value is a value that is less than zero.
