What is a negative mean?
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
Can mean be negative?
Yes, the mean can be negative if the numbers being averaged are negative. For example, if you are averaging temperatures and all of the temperatures are below zero, your average temperature will be a negative number.
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Can the sample mean in statistics be either positive or negative?
It can have either a negative or positive trend
What does a negative z score mean?
It means that it is less than the mean.
Can the magnitude of a vector have a negative vector?
No because magnitude is like length and you cannot have negative length
What is different between negative vector and null vector?
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
Can the magnitude of a vector has negative value?
No, the magnitude of a vector is always a positive value or zero. It represents the length of the vector and is a scalar quantity. Negative values are not associated with the magnitude of a vector.
What is meant by negative vector?
A negative vector is a vector that has the opposite direction of the original vector but the same magnitude. It is obtained by multiplying the original vector by -1. In other words, if the original vector points in a certain direction, the negative vector points in the exact opposite direction.
When should you express a vector along the x-axis as a negative vector?
You should express a vector along the x-axis as negative when it points in the negative x-direction relative to a chosen positive direction. This convention helps maintain consistency with vector addition and trigonometric methods.
When should you express a vector along the x axis as a negative vector?
When the arrow representing the vector would point toward negative x.
What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
Can the magnitude of a vector be negative?
No, the value can't be negative because magnitude of a vector is just how long it is regardless of its direction. :-)
Can the magnitude of a vector have a negative value?
The magnitude of a vector is always treated as non negative and the minus sign indicates the reversal of that vector through an angle of 180 degree.
What decscribes a vector?
A vector is a quantity described by size and direction. Mathematically, the square of a vector is negative, e.g. i^2 = -1, thus a quantity whose square is negative is a vector, e.g. 5i is a vector because (5i)^2 = -25.
Can a vector have a component greater than the magnitude of vector?
no a vector cannot have a component greater than the magnitude of vector
Can scalar be a negative number?
Yes, a scalar can be a negative number. For instance: c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector. Let c = -1 for instance. Then, we have this vector: <-x₁,-x₂> Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs. In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.
