What are the characteristics of probability?
Probability is a numerical value defined for a set of outcomes. It is non-negative and such that the sum or integral over all possible outcomes is 1.
What is the meaning of a negative z score?
A negative z score is a value that is less than the mean value.
If sensitivity and specificity remain constant what is the relationship of prevalence to predictive value positive and predictive value negative?
positive predictive value and negative predictive value wil not be affected.
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 re the three criteria needed for something to be a probability distribution?
A probability distribution must have a well defined domain - that is, the set of possible outcomes.For each possible outcome, there must be a non-negative value associated - the probability of that outcome.The sum of the probabilities, over all possible outcomes, must be 1.
Is it possible for the specific heat of a substance to have a negative value?
No, it is not possible for the specific heat of a substance to have a negative value.
Is it possible for flux to have a negative value?
Yes, it is possible for flux to have a negative value. This occurs when the magnetic field and the area vector are in opposite directions, leading to a negative flux value.
Is it possible for the tension force in a system to have a negative value?
Yes, it is possible for the tension force in a system to have a negative value. This can occur when the direction of the force is opposite to the direction assumed in the calculation, resulting in a negative value.
Is it possible for power to have a negative value?
Yes, power can have a negative value when it represents a decrease in energy or influence.
Is it possible for torque to have a negative value?
Yes, torque can have a negative value when it causes a rotational force in the opposite direction.
What is it called when the absolute value of a number is negative?
An absolute value can never be a negative. An absolute value is just the distance the # is from the zero...so again for it to be negative thats not possible
Is it possible for the percent difference to be negative?
Yes, it is possible for the percent difference to be negative when comparing two values. This occurs when the second value is greater than the first value, resulting in a negative percentage difference.
Is it possible for the coefficient of friction to have a negative value?
Yes, it is possible for the coefficient of friction to have a negative value in certain situations, such as when dealing with lubricated surfaces or materials with unique properties.
Is it possible for displacement to have a negative value?
Yes, displacement can have a negative value if an object moves in the opposite direction of its initial position.
Is it possible for electric flux to have a negative value?
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
Is it possible for the moment of inertia to have a negative value?
No, the moment of inertia cannot have a negative value. It is always a non-negative quantity that represents an object's resistance to changes in its rotational motion.
Is it possible for the change in enthalpy, represented as H, to have a negative value in a chemical reaction?
Yes, it is possible for the change in enthalpy (H) to have a negative value in a chemical reaction, indicating that the reaction releases heat energy.
