How do you make a stem and leaf diagram?

Answer 1

Let's say you have this data:

1. 01
2. 02
3. 10
4. 11
5. 20
6. 21
7. 30

Enumerate the stem of the data.

0,1,2, and 3 are stems since it is found first to the left.

*Note that two digits like 234 have a stem of23.

Enumerate the leaf.

0-12 {01 and 02: the leaf are 1 and 2 since they are found first to your right}

1-01 {same applies}

2-01 {same applies}

3-0 {same applies, the leaf is 0 since 0 is found first to the right of 30}

There you have it! A stem and leaf diagram.

Range formula:

highest data-lowest data=range

So, 30-1 is 29. 29 is the range.
