# How to create a box plot

### How do you make a 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. A vertical line goes through the**box**at the median.### What are the 5 values needed to create 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.### How do I create a Boxplot in Word?

To

**draw a boxplot**, select your range of data (A1:A100), then go to the tab Insert , find the icon Insert Column or Bar Chart and select More Column Charts In the long list of charts in the tab All Charts , click on**Box**& Whisker and OK . The following chart appears.### How do you read box plots?

**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).

### Can Excel make box and whisker plots?

**Excel**doesn’t offer a

**box-and-whisker**chart. Instead, you

**can**cajole a type of

**Excel**chart into

**boxes and whiskers**. Instead of showing the mean and the standard error, the

**box-and-whisker plot**shows the minimum, first quartile, median, third quartile, and maximum of a set of data. The median divides the

**box**.

### Can you make a box plot in Excel?

While

**Excel**2013 doesn’t have a**chart**template for**box plot**,**you can create box plots**by doing the following steps: Calculate quartile values from the source data set.**Create**a stacked column**chart**type from the quartile ranges. Convert the stacked column**chart**to the**box plot**style.### How do you make a box and whisker plot with two sets of data in Excel?

**Create a box and whisker**chart- Select your
**data**—either a single**data**series, or**multiple data**series. (The**data**shown in the following illustration is a portion of the**data**used to**create**the sample chart shown above.) - On the ribbon, click the Insert tab, and then click. (the Statistical chart icon), and select
**Box and Whisker**.

### How do you find Q1 and Q3?

**Q1**is the median (the middle) of the lower half of the data, and

**Q3**is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21).

**Q1**= 7 and

**Q3**= 16. Step 5: Subtract

**Q1**from

**Q3**.

### How do you do box and whisker plots?

**In a**

**box and whisker plot**:- the ends of the
**box**are the upper and lower quartiles, so the**box**spans the interquartile range. - the median is marked by a vertical line inside the
**box**. - the
**whiskers**are the two lines outside the**box**that extend to the highest and lowest observations.

### How do you make a box and whiskers plot?

To

**create**a**box-and-whisker plot**, we start by ordering our data (that is, putting the values) in numerical order, if they aren’t ordered already. Then we find the median of our data. The median divides the data into two halves. To divide the data into quarters, we then find the medians of these two halves.### What does a box plot tell you?

In descriptive statistics, a

**box plot**or**boxplot**(also known as**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 through displaying the data quartiles (or percentiles) and averages.### How do you compare box plots?

**Guidelines for**

**comparing boxplots****Compare**the respective medians, to**compare**location.**Compare**the interquartile ranges (that is, the**box**lengths), to**compare**dispersion.- Look at the overall spread as shown by the adjacent values.
- Look for signs of skewness.
- Look for potential outliers.

### What do whiskers mean in a box plot?

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.### Does a box and whisker plot show standard deviation?

In addition to

**showing**median, first and third quartile and maximum and minimum values, the**Box and Whisker**chart is also used to depict Mean,**Standard Deviation**, Mean**Deviation**and Quartile**Deviation**.### What is a whisker diagram?

Given some data, we can draw a box and

**whisker diagram**(or box**plot**) to show the spread of the data. The**diagram**shows the quartiles of the data, using these as an indication of the spread. The**diagram**is made up of a “box”, which lies between the upper and lower quartiles.### What does it mean when a box plot has no whiskers?

A simpler formulation

**is**this:**no**whisker will be visible if the lower quartile**is**equal to the minimum, or if the upper quartile**is**equal to the maximum.### What does a uniform box plot look like?

**Uniform**– The data is spread equally across the range. There

**are**no clear peaks in these graphs, since each data entry appears the same number of times in the set. Notice in the

**boxplot**how each section is of equal length: min to Q

_{1}, Q

_{1}to median, median to Q

_{3}, and Q

_{3}to max. These graphs

**are**also symmetric.

### What does it mean if a Boxplot is positively skewed?

**Positively Skewed**: For a distribution that is

**positively skewed**, the

**box plot**will show the median closer to the lower or bottom quartile. A distribution is considered “

**Positively Skewed**”

**when mean**> median. It

**means**the data constitute higher frequency of high valued scores.

### What does positively skewed mean?

In statistics, a

**positively skewed**(or right-**skewed**) distribution**is**a type of distribution in which most values are clustered around the left tail of the distribution while the right tail of the distribution**is**longer.### Is left skewed positive or negative?

A

**left**–**skewed**distribution has a long**left**tail.**Left**–**skewed**distributions are also called**negatively**–**skewed**distributions. That’s because there is a long tail in the**negative**direction on the number line.**Right**–**skewed**distributions are also called**positive**–**skew**distributions.### What does a left skewed box plot mean?

longer tail on the

**left means skewed**to the**left means mean**on the**left**of median (smaller) longer tail on the**right means skewed**to the**right means mean**on the**right**of median (larger) tails equally long**means**normal**means mean**about equal to median.
