Both the upper and the lower quartiles are displayed as.
And, there is a vertical line which shows the Median value. Rectangles are drawn for showing the second and the third quartiles. Also makes comparisons quickly and easily. The dialog box for Box-and-Whisker plot is similar to the one for Summary. Box plots are graphical tools that lets you easily visually compare variation between the data sets evaluated. the median is marked by a vertical line inside the box. In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range. For a detailed description of a Box-and-Whisker plot, see Construction of a Box-and-Whisker plot. A box and whisker plot (sometimes called a boxplot) is a graph that presents information from a five-number summary.

With performance-based admissions and no application process, the MS-DS is ideal for individuals with a broad range of undergraduate education and/or professional experience in computer science, information science, mathematics, and statistics. The Box-and-Whisker plot (Tukey, 1977), or boxplot, displays a statistical summary of a variable: median, quartiles, range and possibly extreme values. The MS-DS is an interdisciplinary degree that brings together faculty from CU Boulder’s departments of Applied Mathematics, Computer Science, Information Science, and others. This course can be taken for academic credit as part of CU Boulder’s Master of Science in Data Science (MS-DS) degree offered on the Coursera platform. Finally, you will learn the basics of sampling error, sampling distributions, and errors in decision-making. The centerline of the box marks the median.
You will analyze data sets using the appropriate probability distribution. Boxplot (or Box-and-Whisker Plot) Summarizes data into a 5-numbersummary: median, the first and the third quartiles (Q1 and Q3), minimum, and maximum. You will learn four probability distributions commonly used in the analysis of data. You will describe data both graphically and numerically using descriptive statistics and R software. In this course, you will learn the basics of understanding the data you have and why correctly classifying data is the first step to making correct decisions.
