Question 1
In a stem-and-leaf diagram, what does the 'leaf' represent in a data point?

- B) The first digit of the value
- C) The total sum of all values
- D) The range of the data set

Question 2
If a stem-and-leaf diagram has a stem of 4 and a leaf of 7, what is the value represented?

- A) A key explaining the notation
- B) A title naming the data set
- C) A grid showing every interval
