What determines how close a measurement is to the true or accepted value?
This value is variable and different for each type of measurement. The error can be absolute or relative. A measurement without any error doesn't exist.
What is the size of error for a measurement ranging from 0 to 3?
The absolute error can be as large as 1.5
Which level of measurement in statistics is used for weight?
Ration- the highest level of measurement in terms of statistics which it is an absolute zero, and It is under the quantitative variable(numerical).
Can absolute value ever be negative?
No. An absolute value will always be positive, as it is a measurement of distance from zero on a number line.* * * * *Pedantically, not quite! It will always be non-negative: it can be 0.
What is a vector measurement?
A measurement that has magnitude and direction. The magnitude is equal to the absolute value of the vector measurement. For example, Velocity is a vector measurement. A velocity of -20 miles per 1 second would suggest moving away from the origin point in a two-dimensional measurement at a rate of 20 miles per 1 second. The absolute value of this would be 20 miles per 1 second, which would also be the speed. Therefore, speed is the magnitude of Velocity. Subsequently, any measurement that has a magnitude, but no direction, is not a Vector measurement, but rather a scalar measurement. Some examples of vector measurements would be Displacement, Velocity, and Acceleration.
