What is the key to a stem and leaf plot?

What is the key to a stem and leaf plot?

The Stem and Leaf Plot is an interesting way to showcase data. When reading a stem and leaf plot, you will want to start with the key. It will guide you on how to read the other values. The key on this plot shows that the stem is the tens place and the leaf is the ones place.

Is it necessary for every stem and leaf plot to have a key?

The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem). The ones digits will be the stem values, and the tenths will be the leaves. Properly, every stem-and-leaf plot should have a key.

How does a stem leaf plot work?

A plot where each data value is split into a “leaf” (usually the last digit) and a “stem” (the other digits). For example “32” is split into “3” (stem) and “2” (leaf). The “stem” values are listed down, and the “leaf” values are listed next to them.

How do you do a stem plot?

Steps for Making Stem-and-Leaf Plots

  1. Step 1: Determine the smallest and largest number in the data. The game stats are as follows:
  2. Step 2: Identify the stems.
  3. Step 3: Draw a vertical line and list the stems to the left of the line.
  4. Step 4: Fill in the leaves.
  5. Step 5: Sort the leaf data.

What are split stems in statistics?

It is called a split stemplot because each category is split into two. For example, if you look at the stem (in the center), the number “5” appears twice. The numbers 0-5 in the leaf are in the first, or upper, row and the numbers 8 to 9 are in the second, or lower, row. An example of a split stem-and-leaf plot.

What is the median in a stem and leaf diagram?

Median = middle value Cross off the data in the Stem and Leaf diagram until you get to the middle values (crossing off from each end as you go along): You cannot have two medians, so the median will be half-way between 1 and 3. The highest value is 31.

How do you find the range in a stem and leaf diagram?

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 the mean and mode?

Mean: Add up all the numbers of the set. Divide by how many numbers there are. Mode: The number that occurs the most.
