# What can not be determined from a box plot?

## What can not be determined from a box plot?

In fact, you can’t tell the sample size by looking at a boxplot; it’s based on percentages of the sample size, not the sample size itself. Although a boxplot can tell you whether a data set is symmetric (when the median is in the center of the box), it can’t tell you the shape of the symmetry the way a histogram can.

## What does a box plot reveal?

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.

Can a boxplot have no whiskers?

For a box-and-whisker plot you order the data numerically from smallest to largest and find the lower quartile, median and upper quartile. The median is 2, the lower quartile (the median of the values less than the median) is 1 and the upper quartile is 3. Thus the box extends from 1 to 3 are there are no whiskers.

### Which of the following can be determined from a box and whisker plot?

Answer: Median. Step-by-step explanation: Using a box and whisker plot you can find the Minimum, Maximum, and Median of your equation.

### Which of the following is not included in a five number summary?

2 Answers. Actually its the mean. The 25th percentile is Q1 which is used to calcualte inter-quartile range i.e. The mean has nothing to do with the five number summary or box and whisker plot.

Which of the following statistics Cannot be determined from a Boxplot?

The interquartile is the difference between the third quartile and first quartile. From the box plot we can determine median, Q1, Q3 and interquartile range. We cannot determine the Mean.

## What is the box and whiskers plot used to show quizlet?

box and whisker plot. Charts that shows upper quartile, lower quartile and the interquartile range, it uses a box and lines. median. Middle number of a data set when the data is listed from least to greatest.

## What are the dots on a box and whisker plot?

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.

What does a box plot without whiskers mean?

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. (There are other cases in which no whisker is visible.)

### Which of the following is not considered a measure of spread?

Hence, Quartile is not the measure of dispersion. A quartile is a measure of the spread of values above or below the mean by dividing the distribution into four groups.

Which of the following is not one of the five numbers needed to make a Boxplot?

Which of the following is NOT one of the five numbers needed to make a​ boxplot? The mean is not shown in a​ boxplot, so it is not used to construct boxplots.

## What do you need to know about box plots?

Box plots are a type of graph that can help visually organize data. To graph a box plot the following data points must be calculated: the minimum value, the first quartile, the median, the third quartile, and the maximum value.

## What are the five numbers in a box plot?

A Box Plot is the visual representation of the statistical five number summary of a given data set. A Five Number Summary includes: Minimum. First Quartile. Median (Second Quartile) Third Quartile. Maximum.

How is a box plot used in chartio?

The Chartio version of the Box Plot is close to the original definition and presentation, and is used to take a subset of data and quickly and visually show the five number summary of that data set. Also, in Chartio’s version, a tool tip is provided that shows all of the data points summarized in the visualization.

### Which is an example of a positively skewed box plot?

Boxplot Distribution The box plot distribution will explain how tightly the data is grouped, how the data is skewed, and also about the symmetry of data. Positively Skewed: If the distance from the median to the maximum is greater than the distance from the median to the minimum, then the box plot is positively skewed.
