Can coefficient of variation be greater than 100?
Yes, the coefficient of variation (CV) can be greater than 100%. The CV is calculated as the ratio of the standard deviation to the mean, expressed as a percentage. If the standard deviation is greater than the mean, which can occur in certain datasets, the CV will exceed 100%, indicating high relative variability compared to the average value.
What is the relative dispersion with the mean of 45000 and a standard deviation of 9000?
Relative dispersion = coefficient of variation = (9000/45000)(100) = 20.
What is the percentage increase from 90 to 125?
% increase = 38.89% % increase =|original value - new value|/original value * 100% = |90 - 125|/90 * 100% = 35/90 * 100% = 3.8889 * 10% = 38.89%
How do you calculate a weighted index?
If you mean a standard index where each value is weighted by a reference value, then you just divide each value by the reference and multiply by 100. For instance, if you want to index x, y, and z based on z: (x/z)*100, (y/z)*100, (z/z)*100 Obviously, your reference value should come out to 100.
What does it mean when positive predictive value of diagnostic test is 100 percent?
100%
Assume that you have a binomial experiment with p 0.5 and a sample size of 100. The expected value of this distribution is?
In a binomial distribution, the expected value (mean) is calculated using the formula ( E(X) = n \times p ), where ( n ) is the sample size and ( p ) is the probability of success. For your experiment, with ( n = 100 ) and ( p = 0.5 ), the expected value is ( E(X) = 100 \times 0.5 = 50 ). Thus, the expected value of this binomial distribution is 50.

What is the zero-lift drag coefficient of Airbus a319-100?
The zero-lift drag coefficient (CD0) of the Airbus A319-100 is typically around 0.022 to 0.025. This coefficient represents the drag experienced by the aircraft when it is not generating any lift, primarily due to factors like skin friction and pressure drag. Variations in this value can occur based on specific configurations and modifications of the aircraft.
What is the temperature coefficient of resistance?
The temperature coefficient of resistance is a number used to predict how the resistance of a material changes with changes in temperature. Typically the units are either resistance per temperature or 1/temperature depending on which equation is used for the calculations. For example, in copper the temperature coefficient of resistance is about 0.0039 per change in degrees Celsius. A positive temperature coefficient of resistance means that the resistance of the material will increase as temperature increases. As per the equation or say unit of resistance temperature coefficient, its definition can be given as below: " Rise in temperature per unit initial resistance, when temperature is raised by one degree Celsius is called the resistance temperature coefficient."
What is the possible range of values for the coefficient of variation?
0% to 100%
What is the ohmic value of two wire rtd?
The ohmic value of a two-wire RTD (Resistance Temperature Detector) typically ranges from 100 ohms to 1000 ohms at 0°C. This value increases with temperature due to the positive temperature coefficient of the RTD material.
What is the absolute value of -100?
The absolute value of -100 (|-100|) is 100.
What is Coefficient of cubical expansion of heavy water?
The coefficient of thermal expansion depends on the temperature and pressure. It a pressure of 1 atmosphere the coefficient of thermal expansion are:at 4 deg C : –0.1321 at 20 deg C : 0.1212 at 50 deg C : 0.4280 at 100 deg C: 0.7454.
What is the highest modulation coefficient and percent modulation possible with a conventional AM system without causing excessive distortion?
the highest modulation coefficient is one (1) and percent modulation is 100
What is 3x plus 1?
It is a binomial algebraic expression. Its value can be evaluated if x is known.
An ordinary glass is filled to the brim with 350 mL of water at 100 C If the temperature decreased to 20C how much water could be added to the glass?
Difference in volume = (initial volume) (coefficient of volume expansion of water) (difference in temperature) coefficient of volume expansion of water=0.0002ml/degree celsius (not sure about the value. Better get help from a teacher.)
What is the binomial factor in the factorization of m15 minus 1000?
(m^5 - 10)(m^10 + 10m^5 + 100)
