Complete the table to find the deviation of each data point.(2 points)

Mean 9.25
Data Point 7 9 9.5 12
Deviation

1 answer

To find the deviation of each data point from the mean, you subtract the mean from each data point. The formula for deviation is:

\[ \text{Deviation} = \text{Data Point} - \text{Mean} \]

Given the mean of 9.25, let's calculate the deviations for each data point:

  1. For the data point 7: \[ \text{Deviation} = 7 - 9.25 = -2.25 \]

  2. For the data point 9: \[ \text{Deviation} = 9 - 9.25 = -0.25 \]

  3. For the data point 9.5: \[ \text{Deviation} = 9.5 - 9.25 = 0.25 \]

  4. For the data point 12: \[ \text{Deviation} = 12 - 9.25 = 2.75 \]

Now, we can complete the table with the deviations:

| Data Point | Deviation | |------------|-----------| | 7 | -2.25 | | 9 | -0.25 | | 9.5 | 0.25 | | 12 | 2.75 |
