1.07.2.3 Skewness and the Adjusted Boxplot Tukey’s boxplot is a graphical tool to visualize the distribution of a univariate data set and to pinpoint possible outliers. In this plot, a box is drawn from the 1st quartile Q1 ≈ x(n/4) to the 3rd quartile Q3 ≈ x(3n/4) of the dat...
箱形图能显示出一组数据的 最大值(Maximum)、最小值(Minimum)、中位数(Median)及上下四分位数(1st/3rd Quartile) ,同时还可以显示 逸出值(Outlier) 。那么，这些值是如何被计算出来的呢？什么样的数据会被判定为逸出值呢？第一四分位数（Q1） ，又称 较小四分位数 ，等于该样本中所有数值由...
Use the Box Plot to investigate the skewness (degree of asymmetry) of a set of data or to graphically compare the effect of multiple categorical inputs (e.g., locations) on a continuous output (e.g., sales). The Box Plot displays the following characteristics of the data: 1st Quartile:...
A box plot (or box-and-whisker plot) is useful to show the distribution of quantitative data and to compare variables. It shows the quartiles of the dataset while the whiskers extend to show the rest of the distribution (except for outliers): Explanations: 1st quartile (Q1): the 25th ...
For each box in the plot: The solid box shows the range of the middle 50% of the Cq values for the target or the sample. The horizontal black bar shows the median Cq value. The black circle shows the mean Cq value. The ends of the vertical lines (or "whiskers") show the ...
A boxplot was made from some data. Find the median, the 1st quartile, the 3rd quartile, the minimum, the maximum, and the range of the data. 2. Make a box-and-whisker plot from the following data sets. a. Initial weights (February) of 14 women in a weight loss study (in pounds...
You also have the 1st quartile and 3rd quartile marked out as the left side and right side of the blue box, respectively. If you analyze and evaluate the plot, you can get a sense of how the data are distributed. Again, the boxplot tells us quite a bit: the median, max, min, etc...

The first quartile, Q1 (or the 25th percentile) represents the median between Q2 and the smallest value within the sample, which falls within the 99% confidence interval. It is shown as the lower edge of the box "body" on the diagram. ...
