weighted mean การใช้

• Alligation medial is merely a matter of finding a weighted mean.
• Another example of a weighted mean is the weighted harmonic mean.
• However, this can be done using the Goldman-Hodgkin-Katz equation or the weighted means equation.
• Scharr operators result from an optimization minimizing weighted mean squared angular error in Fourier domain.
• Statistical analyses involving means, weighted means, and regression coefficients all lead to statistics having this form.
• After having rounded the individual grades, a weighted mean is used to calculate the overall result.
• Probably the best known weighted mean is the weighted arithmetic mean, usually simply called the weighted mean.
• If all the weights are equal, then the weighted mean is the same as the arithmetic mean.
• Probably the best known weighted mean is the weighted arithmetic mean, usually simply called the weighted mean.
• With some values of the parameter, the value of assumes familiar kinds of weighted mean as special cases.
• Therefore data elements with a high weight contribute more to the weighted mean than do elements with a low weight.
• Since only the " relative " weights are relevant, any weighted mean can be expressed using coefficients that sum to one.
• It is common in some markets not to use the actual last traded price but some sort of average / weighted mean.
• It can produce a weighted mean that has less variability than the arithmetic mean of a simple random sample of the population.
• It is calculated as the weighted mean of the frequencies present in the signal, determined using a Fourier transform, with their magnitudes as the weights:
• A measurement of both the dispersion measure and the rotation measure therefore yields the weighted mean of the magnetic field along the line of sight.
• When a weighted mean \ mu ^ * is used, the variance of the weighted sample is different from the variance of the unweighted sample.
• Besides, what that formula is doing is giving you the weighted mean, not the weighted median, so this is kind of all beside the point.
• The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics.
• While weighted means generally behave in a similar fashion to arithmetic means, they do have a few counterintuitive properties, as captured for instance in Simpson's paradox.
