Get Interpreting Box-and-Whisker Plots Worksheet

To determine whether an outlier exists, compare the p-value to the significance level. Usually, a significance level (denoted as α or alpha) of 0.05 works well. A significance level of 0.05 indicates a 5% risk of concluding that an outlier exists when no actual outlier exists.

If outliers are present, the whisker on the appropriate side is drawn to 1.5 * IQR rather than the data minimum or the data maximum. Small circles or unfilled dots are drawn on the chart to indicate where suspected outliers lie. On the other hand, filled circles are used for known outliers.

What is a box and whisker plot? A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.

When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric. When the median is closer to the bottom of the box, and if the whisker is shorter on the lower end of the box, then the distribution is positively skewed (skewed right).

steps: Sort the dataset in ascending order. calculate the 1st and 3rd quartiles(Q1, Q3) compute IQR=Q3-Q1. compute lower bound = (Q1–1.5*IQR), upper bound = (Q3+1.5*IQR) loop through the values of the dataset and check for those who fall below the lower bound and above the upper bound and mark them as outliers.

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.

How to Interpret Box Plot in Excel? If the distribution is symmetric, the median lies exactly in the center of the box. In such a case, the distance between the first and second quartiles and the second and third quartiles is the same. ... If the distribution is skewed, the median is not in the center of the box.

If outliers are present, the whisker on the appropriate side is drawn to 1.5 * IQR rather than the data minimum or the data maximum. Small circles or unfilled dots are drawn on the chart to indicate where suspected outliers lie. On the other hand, filled circles are used for known outliers.

Basically, whenever the median is closer to the lower bound of the box, and the upper whisker is longer than the lower one, it indicates that the distribution is right-skewed (the skewness is positive).

Boxplots are a standardized way of displaying the distribution of data based on a five number summary (“minimum”, first quartile (Q1), median, third quartile (Q3), and “maximum”). This type of plot is used to easily detect outliers.
