Part 5 - box plot 两端是最大最小值,箱子两端1st 和 3rd,中间是median 栗子1: 对称 栗子2: 有outlier的情况 栗子3: 缺点为看不清gap和cluster 栗子4: 当有很多组数据是,箱型图就能非常直观的告诉我们数据组之间的差别 。 总而言之,箱线图为我们提供了 非常漂亮的图形化图片。 当我们有两组或更多组观察...
所谓统计学中的箱线图(box plot)就是对四分位数的绘图。 所谓正态分布(Normal distribution),也称“常态分布”,又名高斯分布(Gaussian distribution)。若随机变量X服从一个数学期望为μ、方差为σ2的正态分布,则记为N(μ,σ2)。正态分布的期望值μ决定了其概率密度图的位置,标准差σ决定了分布的幅度。当μ ...

Figure 5: Box plot indicating statistical meanFor the cereal data, the mean is higher than the median. The difference between the mean and median tells you that these data are skewed and not likely to be from a normal distribution. With JMP, you can also add features to graphs. The box...

boxPlot3D(x) creates a three dimensional box plot of the data in x. If x is 3D a matrix, boxPlot3D creates one box for each column. Example, create a 3D matrix with normal distributions with different means:xx=randn(50,2,4)+repmat((permute([0 1 2 -2;1 2 3 4],[3 1 2]))...

On the downside, a box plot’s simplicity also sets limitations on the density of data that it can show. With a box plot, we miss out on the ability to observe the detailed shape of distribution, such as if there are oddities in a distribution’smodality(number of ‘humps’ or peaks)...
