A When a distribution is positively skewed the right side tail is longer than normal due to outliers. The mean will exceed the median, and the median will generally exceed the mode because large outliers falling to the far right side of the distribution can dramatically influence the mean.反馈...
Skewness is caused by the magnitude of positive deviations from the mean being either larger or smaller than the magnitude of negative deviations from the mean. Each side of a skewed distribution is not a mirror image of the other. Peakedness of a distribution is measured by kurtosis. 统计:共...
aConversely, if they are very different, the distribution is probably skewed. The more skewed a distribution is, the more these indicators are likely to diverge. They will diverge in different directions for positive and negative skewing. 相反地,如果他们是非常不同的,发行大概被歪曲。 越被歪曲发行...
SAMPLE ANSWERS: A right skewed distribution means that... the mean is to the right of the median. OR the mean is lower (smaller value) than the median. OR the mean is pulled down because of the larger data outlying to the right of the majority of the data.反馈...

For example, the mode of 2, 3, 3, 5, 7, and 10 is 3. For a symmetrical distribution of a group of numbers, these three measures of central tendency are all the same. For a skewed distribution of a group of numbers, they can be different. Examples Copy the example data in the ...
The sum of relative frequencies in a distribution always equals 1. a) True b) False There is a universally accepted way to interpolate quartiles in datasets. a. True. b. False. True or False: There are four quartiles that divided the data into four ...
