What is box plot how do you interpret it?
A boxplot is 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”). It can also tell you if your data is symmetrical, how tightly your data is grouped, and if and how your data is skewed.
How do you read a boxplot range?
The middle half of a data set falls within the interquartile range. In a boxplot, the interquartile range is represented by the width of the box (Q3 minus Q1). In the chart above, the interquartile range is equal to about 7 minus 3 or about 4.
How do you interpret two Boxplots?
Start with the boxes. They represent the interquartile range, or the middle half of the values in each group. If two boxes do not overlap with one another, say, box A is completely above or below box B, then there is a difference between the two groups. Non-overlapping boxes, groups are different.
What are whiskers in Boxplot?
A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles. The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles.

How do you describe a Boxplot in a paper?
Box Plots and How to Read Them The box ranges from Q1 (the first quartile) to Q3 (the third quartile) of the distribution and the range represents the IQR (interquartile range). The median is indicated by a line across the box. The “whiskers” on box plots extend from Q1 and Q3 to the most extreme data points.
Do box plots show mean?
You cannot find the mean from the box plot itself. The information that you get from the box plot is the five number summary, which is the minimum, first quartile, median, third quartile, and maximum.
How do you describe a Boxplot distribution?
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).

What is the line in a Boxplot?
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. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.
What are the dots in a Boxplot?
Dots represent those who ate a lot more than normal or a lot less than normal (outliers). If more than one outlier ate the same number of hamburgers, dots are placed side by side.
How do you read a box plot?
How to Read a Box Plot. A boxplot is a way to show a five number summary in a chart. The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range. At the ends of the box, you” find the first quartile (the 25\% mark) and the third quartile (the 75\% mark).
What is a box plot and when to use it?
A boxplot is a graph that gives you a good indication of how the values in the data are spread out . Although boxplots may seem primitive in comparison to a histogram or density plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.
When to use box plots?
Use box and whisker plots when you have multiple data sets from independent sources that are related to each other in some way. Examples include test scores between schools or classrooms, data from before and after a process change, similar features on one part such as cam shaft lobes, or data from duplicate machines manufacturing the same products.
How do you find the median of a box plot?
Steps Gather your data. Organize the data from least to greatest. Find the median of the data set. Find the first and third quartiles. Draw a plot line. Mark your first, second, and third quartiles on the plot line. Make a box by drawing horizontal lines connecting the quartiles. Mark your outliers.
