Box And Whisker Skewness Diagram. Solution for iv Use the stem-and-leaf diagram above to draw a box-and-whisker diagram. Whisker chart displays the spread and skewness in a batch of data through its five-number summary.
Box-and-whisker plots are a really effective way to display lots of information. Another property of a symmetric distribution is that its median second quartile lies in the middle of its first and third quartiles. Two or more data can be compared.
These plots contain the range interquartile range median lower value upper value lower quartile and upper.
Students learn to make a box-and-whisker plot for a given. If the whisker to the right of the box is longer than the one to the left there is more extreme values towards the positive end and so the distribution is positively skewed. It has many advantages. To find out unusual observationserrors in the data set.
