# What does a stem and leaf plot show?

A stem and leaf plot is a way to plot data where the data is split into stems (the largest digit) and leaves (the smallest digits). The stem and leaf plot is used like a histogram; it allows you to compare data. While a histogram uses bars to represent amounts, the leaves of the stemplot represent amounts.

## In the same way what can a stem and leaf plot detect?

Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers themselves to show pretty much the same information.## Accordingly, we may wonder what is the use of stem and leaf plot?

A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.## In like manner how do stem and leaf diagrams work?

The "stem" values are listed down, and the "leaf" values go right (or left) from the stem values. The "stem" is used to group the scores and each "leaf" shows the individual scores within each group.## Do you have your own answer or clarification?

#### What is an ordered stem and leaf diagram?

In such a diagram, the "stem" is a column of the unique elements of data after removing the last digit. The final digits ("leaves") of each column are then placed in a row next to the appropriate column and sorted in numerical order. This diagram was invented by John Tukey.

#### How do you find the percentile in a stem plot?

We first need to compute the location for each percentile, then use the sorted data to locate the percentile. k 100 · n = 10 100 · 40 = 4 Since the value of L is a whole number, we use equation (1). P10 = 4th value + 5th value 2 = 54 + 56 2 = 55. 1 Find the median.

#### How do you find the median and mode of a stem-and-leaf plot?

You can use a stem-and-leaf plot to find the mean, median and mode of a set of data. To find the mean, add up all of the numbers in the set and divide by the number of values that you added. Then, divide by the number of values, which is 16. After rounding, the answer is 47.

#### What does a stem plot show that a Boxplot does not?

0 6 6. 1 A stem-and-leaf plot shows the shape and distribution of data. So basically, stem plots allows you to accurately see a distribution of the figures, while a box plot tells you about the median, upper/lower quartiles, theinterquartile range and the data range.

#### How do you find the maximum and minimum of a stem and leaf plot?

The greatest number is the last stem and the last leaf on the chart. In this case, the largest number is 55. To find the range, subtract the smallest number from the largest number. This difference will give you the range.

#### How do you find Q1?

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.

#### What is the z score for the third quartile?

25) and the third quartile is . 67.

#### Do stem and leaf plots have to be in order?

Usually, a stem and leaf plot is ordered, which simply means that the leaves are arranged in ascending order from left to right. Also, there is no need to separate the leaves (digits) with punctuation marks (commas or periods) since each leaf is always a single digit.

#### How is a standard normal distribution defined?

The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. For the standard normal distribution, 68% of the observations lie within 1 standard deviation of the mean; 95% lie within two standard deviation of the mean; and 99.9% lie within 3 standard deviations of the mean.

#### What is the first quartile?

First quartile: the lowest 25% of numbers. Second quartile: between 25.1% and 50% (up to the median) Third quartile: 51% to 75% (above the median) Fourth quartile: the highest 25% of numbers.

#### What is the difference between a histogram and a stem leaf plot?

A stem and leaf plot is a way to plot data where the data is split into stems (the largest digit) and leaves (the smallest digits). The stem and leaf plot is used like a histogram; it allows you to compare data. While a histogram uses bars to represent amounts, the leaves of the stemplot represent amounts.

#### What is third quartile example?

An Example

In other words, the median is: (7 + 8)/2 = 7.5. Here the median is (15 + 15)/2 = 15. Thus the third quartile Q

In other words, the median is: (7 + 8)/2 = 7.5. Here the median is (15 + 15)/2 = 15. Thus the third quartile Q

_{3}= 15.#### What is the lower quartile of a stem-and-leaf plot?

The quartiles separate the data into four equally sized parts. The other two values to remember are the lower quartile (LQ), which divides the lower 50% of the data points into two equally sized parts, and the upper quartile (UQ), that separates the higher 50% of the data points into two equally sized groups.

#### Is the First Quartile the same as the 25th percentile?

The first quartile, Q1 , is the same as the 25 th percentile, and the third quartile, Q3 , is the same as the 75 th percentile. The median, M , is called both the second quartile and the 50 th percentile.

#### How do you read a stem and leaf diagram?

In a stem and leaf plot, the stem is like the first digit and the stem would be the number following it. For example, in number 24, the 2 is the stem and 4 would be the leaf. In the table, in sal's video, you read from left to right. you take the stem and tack the leaf number at the end.

#### How do you find the third quartile?

The third quartile, denoted by Q

_{3}, is the median of the upper half of the data set. This means that about 75% of the numbers in the data set lie below Q_{3}and about 25% lie above Q_{3}.#### How do you find the third quartile of a normal distribution?

Quartiles: The first and third quartiles can be found using the mean µ and the standard deviation σ. Q1 = µ − (. 675)σ and Q3 = µ + (. 675)σ.

#### What is the interquartile range of a normal distribution?

In a standard normal distribution (with mean 0 and standard deviation 1), the first and third quartiles are located at -0.67448 and +0.67448 respectively. Thus the interquartile range (IQR) is 1.34896.

#### What is the formula of quartile?

First Quartile(Q1)=((n+1)/4)

^{t}^{h}Term also known as the lower quartile. The second quartile or the 50th percentile or the Median is given as: Second Quartile(Q2)=((n+1)/2)^{t}^{h}Term. The third Quartile of the 75th Percentile (Q3) is given as: Third Quartile(Q3)=(3(n+1)/4)^{t}^{h}Term also known as the upper quartile.#### How do you know if a stem and leaf plot is skewed?

Skewed: As with the horizontal skewing of a histogram, stem plots with a obvious skew toward one end or the other tend to indicate an increased number of outliers either lesser than the mode (skewed down – correlating to a left-skew in a histogram) or greater than the mode (skewed up – correlating to a right-skewed

#### Can you skip stems in a stem and leaf plot?

Creating a stem and leaf plot

The stem is everything before the final digit, and the leaf is the final digit. Write the stems in a vertical column and don't skip stems just because they don't have any data.
