## Example Questions

### Example Question #1 : Stem And Leaf Plots

Above is a stem-and-leaf representation of the scores on a test administered to a group of students. What was the mode of the scores?

**Possible Answers:**

The set of scores has more than one mode.

**Correct answer:**

The mode of the data set is the score that occurs the most frequently.

Each "stem" in the left column represents the tens digits of the scores; each of the numbers in its row, or "leaf" represents the units digits. The entry that occurs the most frequently is represented by the "6" in the "7" row, so 76 is the one and only mode.

### Example Question #2 : Representing Data

Above is a stem-and-leaf plot for the test scores administered to a group of students.

What was the median score?

**Possible Answers:**

**Correct answer:**

Each of the numbers in the leftmost column, or "stems" represents the tens digits of one or more scores; each digit in one of the rows, or "leaf", represents the units digit of a score.

The median score is the score that occurs in the middle when the scores are arranged from least to greatest, which there are, so we count up until we get to the middle score. There are 53, so we look for the

highest (or lowest) score. Counting up 27 scores, we get to the "4" in the "7" row, which represents a score of 74. This is the median.

### Example Question #73 : Algebra Ii

List the data values for the given Stem and Leaf plot.

**Possible Answers:**

24, 25, 40, 45, 52

3, 7, 8, 24, 25, 45, 52

2, 5, 25, 30, 42, 52, 70, 80

3, 7, 8, 24, 25, 40, 45, 52

**Correct answer:**

3, 7, 8, 24, 25, 40, 45, 52

The tens-digits are in the Stem column (left-side) while the ones-digits are in the Leaf column (right-side). Therefore, the data in the Stem and Leaf plot can be written as:

### Example Question #74 : Algebra Ii

**Possible Answers:**

32, 35, 36, 63, 65, 667, 68, 83, 89

32, 35, 36, 63, 67, 68, 83, 89, 90

32, 35, 36, 63, 65, 67, 68, 83, 89, 90

23, 53, 63, 36, 56, 76, 86, 38, 98, 9

**Correct answer:**

32, 35, 36, 63, 65, 67, 68, 83, 89, 90

The tens-digits are placed in the Stem column (left-side) and the ones-digits are placed in the Leaf column. Therefore, the data in the Stem and Leaf plot can be written as:

### Example Question #75 : Algebra Ii

**Possible Answers:**

13, 15, 42, 49, 71, 73

13, 15, 17, 42, 49, 71, 73

13, 15, 17, 42, 71, 73

31, 51, 71, 24, 94, 17, 37

**Correct answer:**

13, 15, 17, 42, 49, 71, 73

The tens-digits are placed in the Stem column (left-side) and the ones-digits are placed in the Leaf column. Therefore, the data in the Stem and Leaf plot can be written as:

### Example Question #76 : Algebra Ii

List the data values for the given Stem and Leaf plot.

**Possible Answers:**

38, 41, 62, 63, 65, 67

07, 38, 62, 63, 65, 67

70, 83, 14, 26, 23, 25, 27

7, 38, 41, 62, 63, 65, 67

**Correct answer:**

7, 38, 41, 62, 63, 65, 67

The tens-digits are placed in the Stem column (left-side) and the ones-digits are placed in the Leaf column. Therefore, the data in the Stem and Leaf plot can be written as:

### Example Question #2 : Stem And Leaf Plots

Create the Stem and Leaf plot for the given data values.

**Possible Answers:**

**Correct answer:**

The tens-digits are placed in the Stem column (left-side) and the ones-digits are placed in the Leaf column.

The list of values is:

**34, 54, 6, 95, 22, 4**

This data can also be written as *04, 06, 22, 34, 54, 95*

### Example Question #3 : Stem And Leaf Plots

Create the Stem and Leaf plot for the given data values:

6, 8, 10, 23, 35, 43, 44, 45, 48

**Possible Answers:**

**Correct answer:**

The tens-digits are placed in the Stem column (left-side) and the ones-digits are placed in the Leaf column.

The data values are:

**6, 8, 10, 23, 35, 43, 44, 45, 48**

We can rewrite it as follow

06, 08, 10, 23, 35, 43, 44, 45, 48

### Example Question #4 : Stem And Leaf Plots

Which of the following represents the correct median value of the above Stem and Leaf Plot?

**Possible Answers:**

Impossible to determine based on the data provided.

**Correct answer:**

There are 18 data points in this set, so the median lies halfway between the 9^{th} and 10^{th }sequential data point:

9^{th} Point:

10^{th} Point:

And:

The correct median value of the data set is **74**
