# How do you interpret boxplot whiskers?

## How do you interpret boxplot whiskers?

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 does a box and whisker chart tell you?**

A box and whisker plotâ€”also called a box plotâ€”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. A vertical line goes through the box at the median.

**How do you interpret a boxplot spread?**

If you are interested in the spread of all the data, it is represented on a boxplot by the horizontal distance between the smallest value and the largest value, including any outliers. In the boxplot above, data values range from about 0 (the smallest non-outlier) to about 16 (the largest outlier), so the range is 16.

### What percent of the sophomores spend more than 60 minutes on homework per night?

25%

25% of the sophomores spend between 48 & 60 minutes per night on homework.

**What are box and whisker plots used for in real life?**

You can use “box and whisker plot” in the real world to when you are trying to compare something with another. For example if you want to compare which phone is worth it, you can do this by getting the average of how many people buy the better phone.

**What is the better measure of spread for comparing the box plots?**

The interquartile range (IQR) is the difference between the upper (Q3) and lower (Q1) quartiles, and describes the middle 50% of values when ordered from lowest to highest. The IQR is often seen as a better measure of spread than the range as it is not affected by outliers.

## What is the purpose in a box and whisker plot?

A Box and Whisker Plot is a graphical method for creating and displaying a specific data set . It is often referred to as a box plat or a box and whisker diagram. The diagram is most often used with historical data to provide an analysis of performance over time (for instance, with individual stocks).

**What is the 5 number summary for 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 . 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.

**How is a box and whisker plot used in real life?**

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.

### What are the advantages of box and whisker plots?

Box and whisker plots offer the following advantages: They take up less space. Box and whisker plots use less space when compared to other types of data graphs and charts. They give you information as a whole. Whereas other graphs show you individual changes among data, you can use box and whisker plots to identify trends as a whole. They show outliers. You can compare data much quicker.
