When there are many numbers in a prepare of data, we can construct a stalk-and-leaf plot to evidence the data and make information technology easier to read.

The post-obit diagram shows how to construct a stem-and-foliage plot or stemplot. Scroll downward the page for more than examples and solutions on how to construct and use stalk-and-leafage plots.

Stem-and-Leaf Plot

Drawing A Stalk-And-Leafage Plot

Instance:
Construct a stalk-and-leaf plot for the following fix of data.
28 13 26 12 twenty 14 21 xvi 17 22
17 25 13 30 13 22 fifteen 21 eighteen 18
16 21 18 31 15 19

Solution:
Step ane: Observe the least number and the greatest number in the data set.
The greatest number is 31 (3 in the tens place)
The smallest number is 12 (1 in the tens place)

Step ii: Depict a vertical line and write the digits in the tens places from 1 to 3 on the left of the line. The tens digit form the stems.

Step three: Write the units digit to the right of the line. The units digits class the leaves.

Step 4: Rewrite the units digits in each row from the least to the greatest.

Step 5: Include an explanation (or key).

Interpret A Stem-And-Leaf Plot

Example:
The following stem-and-foliage plot shows the ages of a grouping of people in a room.

a) How many people were in that location in the room?
b) Two people have the same age. What is that historic period?
c) What is the manner, median and hateful of the ages?

Solution:
a) We count the number of digits on the correct of the line (leaves). There were 12 people in the room.

b) The two people were 22 years sometime.

c) The fashion is 22.
The median tin be obtained from the boilerplate 6th and seventh information.
The average of 22 and 24 is 23.
The median age is 23
To go the hateful, we accept to first get the total ages.
17 + eighteen + 19 + 20 + 22 + 22 + 24 + 25 + 26 + 41 + 42 + 44 = 320
The mean = = 26.67
