Graph 1

An unlabeled dot plot. The dot plot has arrows at both ends and ranges from 0 to 5 in increments of 1. There are 2 dots above 0, 4 dots above 1, 5 dots above 2, 3 dots above 3, 2 dots above 4, and 2 dots above 5.

Graph 2

4 to 12 in increments of 1. There are 0 dots above 4, 1 dots above 5, 2 dots above 6, 3 dots above 7, 5 dots above 8, and 5 dots above 9. 3 dots above 10, 1 dot above 11, 0 dots above 12

To determine which graph has a larger standard deviation, we need to analyze the spread of the data points in each graph.

Graph 1:

  • Data:
    • 0: 2 dots
    • 1: 4 dots
    • 2: 5 dots
    • 3: 3 dots
    • 4: 2 dots
    • 5: 2 dots
  • Distribution is centered around 2, with most data points clustered near this value and fewer at the extremes (0 and 5).

Graph 2:

  • Data:
    • 4: 0 dots
    • 5: 1 dot
    • 6: 2 dots
    • 7: 3 dots
    • 8: 5 dots
    • 9: 5 dots
    • 10: 3 dots
    • 11: 1 dot
    • 12: 0 dots
  • This graph shows a wider spread of data values, with data points ranging from 5 to 11, with a peak around 8 and 9.

Conclusion: The standard deviation is a measure of the spread of a set of values. Graph 2 has a wider range (5 to 11) compared to Graph 1 (0 to 5), indicating that Graph 2 likely has a larger standard deviation due to the greater variance in values.

Therefore, the correct response is:

The second graph has a larger standard deviation.
