What Does Skewed Right Mean? While normal distribution is one of the most common forms of distribution, not all data sets follow this basic curve. In other words,some histograms are skewed to the right or left. With right-skewed distribution (also known as "positively skewed" distribution), ...

A. 44%.B. 56%.C. 95%. 正确答案:B 分享到: 答案解析: Because the distribution is skewed, we must use Chebyshev’s Inequality, which states that the proportion of observations within k standard deviations of the mean is at least 1 – (1 / k2). 1– (1 / 1.52) = 0.5555, or 56%...
What does a zero median mean? Describing Data Sets There are various terms that can be used to describe the numbers contained in a data set. Some of these include the mean (or average) of the values, the mode (the number that occurs most frequently in the data set), and the median ...

What problems does skewed data cause? Skewed data indicates the existence of outliers in a data set, which can negatively affect statistical model performance and reduce model accuracy. Skewed data can also be difficult for some types of models to process, so this limits the amount of models av...
