It is a way of presenting data for a set that can be divided into two categories with the aim to make it easier to compare the two subsets. An example could be the weight of boys and girls in a class - where you might want to see if there was an obvious gender difference.
The stem runs down the middle of the diagram, the leaves for one subset (boys) would go on one side of the stem and those for the other subset (girls) would go on the other side.
A stem-and-leaf plot is a convenient way to organize data using numerical order and place value.
It will usually be on a stem, all by itself, a long way from the nearest stem.
It is called a stem-and-leaf diagram or chart.
Yes
It is not. Different people have different preferences for the way in which they can take in data. I'll take a well designed table over a stem and leaf any day.
A stem-and-leaf plot is a convenient way to organize data using numerical order and place value.

The simplest way is to to a back to back comparison. This is where a single stem replaces the two stems, the leaves for one variable are to the left of the stem while those for the other are on the other side.
Usually it would be on a stem all by itself, a long way from the next stem.
A stem and leaf diagram is a visual representation of the distribution of your data, similar to a histogram. The advantage is that a stem and leaf diagram is very quick and easy to put together as it uses only the numbers of your dataset. Let's say you had the following dataset: 32 4 36 4 16 23 30 45 31 6 31 29 which is equivalent to: 32 04 36 04 16 23 30 45 31 06 31 29 or looking at it another way: 3|2 0|4 3|6 0|4 1|6 2|3 3|0 4|5 3|1 0|6 3|1 2|9 I've just placed a "|" as a visual way of separating the tens from the units. The numbers before the "|" (i.e. 0,1,2,3,4) will be our "stems". Each corresponding number after the "|" will form the "leaves" and be placed next to the appropriate stem. When you put it together the stem and leaf diagram looks like this: 0|446 1|6 2|39 3|26011 4|5 The most appropriate stem and leaves depend on the particular dataset. For example, the stem and leaf diagram of the following set of numbers: 100.5 100.4 99.9 100.5 101.4 100.1 100.5 101.9 Would look like this: 099|9 100|54515 101|49
It is called a stem-and-leaf diagram or chart.
Yes
Yes because they organize data in a way that somebody can read it.
It is not. Different people have different preferences for the way in which they can take in data. I'll take a well designed table over a stem and leaf any day.
It is a special way of plotting data in statistics. See link for more.
TallyYou can extend the idea of tally further to what Statisticians refer to as a Stem & Leaf Plot, which is a simple type of histogram. With a Stem & Leaf plot your tallies are placed in 'bins' according to their value, allowing you to observe the distribution of your data.Let's say you have a data set: 0, 7, 10, 13, 18, 19, 21, 29, 55, 57, 59, 59, 60The Stem & Leaf Plot would look like this:0|071|03892|193|4|5|57996|0i.e. '0' becomes '00' and '7' becomes '07' for the purposes of this Stem & Leaf Plot which needs two digits to illustrate its shape in this way.
a stem and leaf plot is so important cause if you turn the plot to the left [counter clockwise] then it will look like an organized graph in order from least to greatest you can find mode, range, and median right a way. glad to help!!!
