A stem and leaf show (likewise called a stem and leaf plot) is a graphical strategy for showing information. It is especially helpful when the information is discrete. A stem and leaf plot is like a histogram with more accuracy. 

A decent stem and leaf plot demonstrates the primary digits of the number (thousands, hundreds or tens) as the stem and demonstrates the last digit (ones) as the leaf. Typically utilizes entire numbers. Anything that has a decimal point is adjusted to the closest entire number. For instance, statures, loads, and so forth. It would appear that a visual diagram when it is turned on its side. 

What are Stem and leaf plots used for? 

A stem and leaf plot is an approach to plot data, where the information is represented as of stems (the biggest digit) and leaves (the littlest digits). This approach is the most quick and efficient way to portray the information. They are easy to interpret and can be developed in least time possible.  

The stem and leaf plot is utilized like a histogram; it enables you to think about information. While a histogram uses bars to speak to sums, the leaves of the stem plot speak to sums. A long leaf implies that "stem" has a lot of information. The stems with the biggest measure of information in the image above are the 2 and 6 stems. 

The biggest spot esteem digits are put in the stem. Stem plots, in reality, aren't normally marked with the spot esteems that the stem speaks to — it's more often than not dependent upon you to make sense of it dependent on the unique situation and information. 

ADVANTAGES & USAGE OF STEM & LEAF PLOT 

Arranges information so it is simpler to locate the middle, mode, and range. 

It helps to find outliers in the data. 

Arranges and analysis the data in a more accurate manner.

Stem-and-leaf used to display relative density and shape of the data

HOW TO MAKE STEM AND LEAF PLOT 

Put the primary digits of each bit of information in numerical request down the left-hand side

Experience each bit of information thus and put the rest of the digits in the best possible line

Redraw the chart putting the bits of information organized appropriately

Include a key

EXAMPLE: Observations recorded for the freshman basketball team. Develop a stem and leaf plot for the following observations

NOTE:  Here is similar information sorted out into a stem-and-leaf plot.

Here the 2 is in the ten’s place for the first observation.

Here the 7 is in the once’s place for the first observation.

Keep in mind: 

- Always put in Key 

- Use your data in the proper order to get the accurate information

Median: 

- To work out the middle, you should locate the center worth 

- If there are two center qualities, you need the normal 

Range: 

- To calculate the Range, subtract the smallest number from the biggest. 

NOTE: A stem and leaf plot is an amazing way to represent data by the frequency. It provides great visual including the data.
