Given the following stem and leaf for temperatures recorded in October:

a. How many temperatures are recorded?

b. What was the highest temperature recorded?

c. What is the coldest (lowest) temperature recorded?

(I apologize for the lack of bars in the graph)

Solution

We need to read this stem and leaf plot to answer the questions.

Step 1: How many temperatures are recorded?

Count up how many numbers are on the right side of the plot. The \"leaves\". In this case there are 15 temperatures recorded.

Step 2: What was the highest temperature recorded?
Go to the last \"stem\" in this case 7, and find the highest \"leaf\". The highest temp recorded is 74.

Step 3: What is the lowest temperature recorded?
Go to the first stem, in this case 4, and find the lowest leaf. The lowest temp recorded is 42.

Hope this helps! :) Let me know if you have any other questions.
