Math Problem Statement
Solution
To answer the question in the image:
The task is to order the three dot plots from the one with the largest standard deviation to the one with the smallest standard deviation. The standard deviation is a measure of how spread out the data points are. The more spread out, the larger the standard deviation; the more concentrated, the smaller the standard deviation.
Analysis of the Dot Plots:
- First Dot Plot (Top): The points are somewhat centered, with a spread covering a range from about 1 to 4. There is a bit of clustering in the center.
- Second Dot Plot (Middle): This plot has most of its points spread out more, especially with a wider gap in the center. The points cover a range from 0 to 5.
- Third Dot Plot (Bottom): The points are at the far left and right ends, with the widest spread possible between the data points, and a clear gap in the middle.
Ordering by Standard Deviation:
- Largest Standard Deviation: The third (bottom) dot plot has the most spread-out points, so it has the largest standard deviation.
- Second Largest: The second (middle) dot plot is spread out but not as much as the third one.
- Smallest Standard Deviation: The first (top) dot plot has the most clustered data points, so it has the smallest standard deviation.
Final Order:
- Top: Third dot plot (bottom of the image).
- Middle: Second dot plot (middle of the image).
- Bottom: First dot plot (top of the image).

Tip: Remember, the standard deviation gives you insight into how much the data varies from the mean. The larger the deviation, the more dispersed the data.
