Descriptive statistics box plot

How do you describe a box plot in statistics?
Boxplots are drawn as a box with a vertical line down the middle, and has horizontal lines attached to each side (known as “whiskers”).
The box is used to represent the interquartile range (IQR) — or the 50 percent of data points lying above the first quartile and below the third quartile — in the given data set..
How do you statistically compare box plots?
Guidelines for comparing boxplots
1. Compare the respective medians, to compare location
2. Compare the interquartile ranges (that is, the box lengths), to compare dispersion
3. Look at the overall spread as shown by the adjacent values
4. Look for signs of skewness
5. Look for potential outliers
What are descriptive statistics of boxplot?
In descriptive statistics, a box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles..
What statistical measure is box 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.
In a box plot, we draw a box from the first quartile to the third quartile..
What statistical properties are shown in a box plot?
In its simplest form, the boxplot presents five sample statistics - the minimum, the lower quartile, the median, the upper quartile and the maximum - in a visual display.
The box of the plot is a rectangle which encloses the middle half of the sample, with an end at each quartile..
What statistics are needed to draw a box plot?
A box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value.
We use these values to compare how close other data values are to them..

Box plots provide a quick visual summary of the variability of values in a dataset.
They show the median, upper and lower quartiles, minimum and maximum values, and any outliers in the dataset.
Outliers can reveal mistakes or unusual occurrences in data.

How to Read A Box Plot

A boxplot is a way to show a five number summary in a chart

How to Read A Box Plot: Steps

Step 1: Find the minimum. The minimum is the far left hand side of the graph, at the tip of the left whisker. For this graph

Example 2

You can easily read a boxplot to find the five number summary. For example

Note on Outliers

Data sets can sometimes contain outliers that are suspected to be anomalies (perhaps because of data collection errors or just plain old flukes)

How do you show a median in a box plot?

The two whiskers extend from the first quartile to the smallest value and from the third quartile to the largest value

The median is shown with a dashed line

It is important to start a box plot with a scaled number line

Otherwise the box plot may not be useful

The following data are the heights of 40 40 students in a statistics class

What are the 5 numbers in a box plot?

The five-number summary is the minimum, first quartile, median, third quartile, and maximum

In a box plot, we draw a box from the first quartile to the third quartile

A vertical line goes through the box at the median

The whiskers go from each quartile to the minimum or maximum

What is a box plot in statistics?

In descriptive statistics, a box plot or boxplot (also known as a box and whisker plot) is a type of chart often used in explanatory data analysis

Box plots visually show the distribution of numerical data and skewness by displaying the data quartiles (or percentiles) and averages
