mean < median < mode 解释: B is correct. For the positively skewed unimodal distribution, the mode is less than the median, which is less than the mean.A is incorrect because, for the positively skewed unimodal distribution, the mode is less than the median (not less than or equal to)...

The paper presents the parametric and nonparametric results of the least squares (mean), quantile (including median) and mode estimations. The examined data are found to be positively skewed for low probabilities and negatively skewed for high probabilities. This observation leads to the striking ...
Explanation: If the mean, median and the mode of a set of numbers are equal, it means,the distribution is symmetric. The more skewed is the distribution, greater is the difference between the median and mean, and we should lay greater emphasis on using the median as opposed to the mean....
Mean, Median, and Mode:The mean is an average of all given data values. It is computed by dividing the sum of values by their count. The median tries to capture the central value in a data set, and does this by determining the middle point when the data is set in ascending order. ...
What is the order of the measures of central tendency from smallest to largest for a positively skewed distribution? i) mode, median, mean ii) median, mode, mean iii) mean, median, mode iv) They are identical. Each measure of the "middle" (the mean, the ...
In a positively skewed distribution, there’s a cluster of lower scores and a spread-out tail on the right. Income distribution is a common example of a skewed dataset.While most values tend to be low, the arithmetic mean is often pulled upward (or rightward) by high values or outliers ...
If the density of x is unimodal and positively skewed, then counterexamples are provided which ... KM Abadir - 《Econometric Theory》 被引量: 30发表: 2008年 Image distortions produced by mean, median and mode filters The paper reviews earlier continuum models of image distortions produced by ...
On a right-skewed histogram, the mean, median, and mode are all different.In this case, the mode is the highest point of the histogram, whereas the median and mean fall to the right of it (or, visually, the right of the peak). Note thatthe mean willalwaysbe to the right of the ...
The Italian distribution is positively skewed while in Germany the distribution is bimodal. In Germany, the mean, marked by an x in the pictures, is smaller than the median, marked by an o, which is smaller than the upper quartile, marked by an asterisk. The plus mark signals the ...
