Question

An illustration shows three rows of data. A vertical line is drawn after the first digit from the left, thereby splitting the rows into a two-column table. The data are as follows: The first row shows digit 4 in the first column and digits 0 0 3 in the second column. The second row shows digit 3 in the first column and digits 7 8 8 8 9 in the second column. The third row shows 2 in the first column and digits 3 6 6 8 in the second column.

Erica makes this stem-and-leaf plot. Which number appears most frequently in the dataset she used?

(1 point)

Answer 1

To determine which number appears most frequently in the dataset Erica used, we can analyze the data presented in the stem-and-leaf plot.

We can decode the data as follows:

• First Row:

  • Stem: 4
  • Leaf: 0 0 3
  • Represents: 40, 40, 43

• Second Row:

  • Stem: 3
  • Leaf: 7 8 8 8 9
  • Represents: 37, 38, 38, 38, 39

• Third Row:

  • Stem: 2
  • Leaf: 3 6 6 8
  • Represents: 23, 26, 26, 28

Now let's list out all the numbers represented:

• From the first row: 40, 40, 43
• From the second row: 37, 38, 38, 38, 39
• From the third row: 23, 26, 26, 28

Now, we can count the frequency of each number:

• 23: 1 time
• 26: 2 times
• 28: 1 time
• 37: 1 time
• 38: 3 times
• 39: 1 time
• 40: 2 times
• 43: 1 time

The number that appears most frequently in the dataset is 38, which appears 3 times.
